Intranasally inoculated Mycoplasma hyorhinis causes eustachitis in pigs. (1/84)

Specific-pathogen-free pigs were experimentally inoculated with Mycoplasma hyorhinis, Pasteurella multocida, or both bacterial isolates to evaluate the role of these bacteria in the pathogenesis of otitis media. Six pigs were inoculated intranasally with 4.4 X 10(8) colony-forming units (CFU) of M. hyorhinis. Twenty-one days later, three of these six pigs were inoculated intranasally with 5.0 X 10(8) CFU of P. multocida. Three additional pigs were also inoculated intranasally at the time with P. multocida alone. Two pigs served as uninoculated controls. Seven days later, all pigs were euthanatized. Histologically, subacute inflammation was found in 10 auditory tubes of six pigs and two tympanic cavities of two pigs inoculated with M. hyorhinis. Immunohistochemically, M. hyorhinis antigens were detected on the luminal surface of eight of 10 inflamed auditory tubes, and ultrastructural examination confirmed mycoplasmal organisms in two pigs. M. hyorhinis was isolated from the inflamed tympanic cavities of two pigs. None of the pigs inoculated only with P. multocida had otitis, and P. multocida was not isolated from the tympanic cavity. These findings indicate that M. hyorhinis can cause eustachitis but rarely otitis media in specific-pathogen-free pigs.  (+info)

Occlusion of the internal carotid artery by means of microcoils for preventing epistaxis caused by guttural pouch mycosis in horses. (2/84)

Occlusion of the internal carotid artery by insertion of intravascular platinum microcoils for guttural pouch mycosis was experimentally evaluated in 9 healthy adult Thoroughbred horses. The internal carotid artery was ligated to its origin, and an arteriotomy was made distal to the ligature, which was then occluded by insertion of the microcoil approximately 13 cm distal to its origin. Cessation of blood flow was determined visually and by angiography at the arteriotomy site. Six horses were evaluated for complication clinically and by endoscopy after surgery. One horse was necropsied after 30 days of surgery for histological evaluation of artery thrombus formation. In the other 3 horses, the blood flow of the right internal carotid artery was monitored, before and after microcoil occlusion of the left internal carotid artery. One or 2 microcoils stopped blood flow within a few minutes. No other abnormal findings were observed clinically. Thrombus was observed in the occluded segment of 1 horse 30 days after insertion; but no abnormalities were detected. The blood flow in the right internal carotid artery increased by approximately 28-58% after occlusion of the left internal carotid artery. This microcoil vascular occlusion technique causes an effective thrombosis, and based on experimental studies and clinical application in 2 horses with epistaxis due to guttural pouch mycosis, this technique would appear to be safe and efficacious.  (+info)

Surfactant protein A and D expression in the porcine Eustachian tube. (3/84)

Surfactant proteins A and D are collectins which are considered to play an important role in the innate immunity of lungs. Our aim was to investigate whether surfactant protein A or D is expressed in the porcine Eustachian tube originating from the upper airways. Both surfactant proteins A and D were present in the epithelial cells of the Eustachian tube, as shown by strong immunostaining. Using RT-PCR and Northern hybridization, these collectins were detected in the Eustachian tube. The present study is the first report demonstrating surfactant protein gene expression in the Eustachian tube. Surfactant proteins A and D may be important in the antibody-independent protection of the middle ear.  (+info)

CT examination of the guttural pouch (auditory tube diverticulum) in Przewalski's Horse (Equus przewalskii). (4/84)

The domestic horse (Equus caballus) have the large symmetrical guttural pouches (the auditory tube diverticulum) formed by saccate bulge of the auditory tube. In this study, CT examination was carried out in the head of Przewalski's horse (Equus przewalskii), the only true wild horse living at present. As results of the examination, Przewalski's horse possessed the large symmetrical guttural pouches divided into medial and lateral compartments by the stylohyoid bone. Moreover, the right and left guttural pouches meet each other at the median part to form a thin septum. As CT sections get close to the part of the occipital condyle, the lateral compartment disappeared, and the medial compartment gradually became small toward the base of the skull. These results indicate that the nuchal-basal part of the medial compartment is not well-developed as compared with the domestic horse.  (+info)

Primary distension of the guttural pouch lateral compartment secondary to empyema. (5/84)

A 6-year-old, 420-kg quarter horse gelding was presented with a 2-month history of difficulty swallowing and dyspnea. The horse was diagnosed with a right guttural pouch empyema with many large chondroids. Two surgeries were required to completely remove all the chondroids from what proved to be a primary distension of the guttural pouch lateral compartment.  (+info)

Distribution of immunoglobulin isotypes and subisotypes in equine guttural pouch (auditory tube diverticulum). (6/84)

To clarify the functions of the equine guttural pouch, the distribution of various immunoglobulin isotypes and subisotypes in the guttural pouch mucosa were examined in healthy horses. IgGa was present in the mucosa of guttural pouch, mucosal lymph nodules and submucosal lymph nodules. IgM was scattered in the mucosal lymph nodules and in the germinal centers of the submucosal lymph nodules. IgGc was recognized only in the submucosal lymph nodules. These immunoglobulin isotypes and subisotypes were found in lymphocytes and plasma cells. On the other hand, IgA was detected in glandular epithelial cells and the surface layer of the mucosal epithelium, as well as in free cells. This finding suggests that IgA is secreted through the glandular epithelium. Based on the above findings, we conclude that the guttural pouch has phylactic ability.  (+info)

Galbreath technique: a manipulative treatment for otitis media revisited. (7/84)

Otitis media is a common disorder that results in numerous visits to the physician each year. Antimicrobials, antihistamines, steroids, and surgery have all been used to treat otitis media; however, the literature makes little mention of osteopathic manipulative treatment in this regard. This article describes a technique that was first described in 1929 by William Otis Galbreath, DO. By simple mandibular manipulation, the eustachian tube is made to open and close in a "pumping action" that allows the ear to drain accumulated fluid more effectively. Physicians can easily teach this procedure to parents for use at home.  (+info)

Expression and localization of lung surfactant protein B in Eustachian tube epithelium. (8/84)

Surfactant protein (SP) B is an essential component of the pulmonary surfactant complex, which participates in reducing the surface tension across the alveolar air-liquid interface. The Eustachian tube (ET) connects the upper respiratory tract to the middle ear, serving as an intermittent airway between the pharynx and the middle ear. Recently, we described the expression of SP-A and SP-D in the ET, suggesting their role in middle ear host defense. Our present aim was to detect whether the expression of SP-B is evident in the porcine ET. With Northern blot analysis, RT-PCR, and in situ hybridizations, SP-B mRNA was identified and localized in the ET epithelium. The cellular localization of SP-B was revealed with immunohistochemistry, electron microscopy, and immunoelectron microscopy. The protein was found in the secretory granules of epithelial cells and also attached to the microvilli at the luminal side of these cells. The SP-B immunoreactivity of aggregates isolated from ET lavage fluid was similar to that isolated from bronchoalveolar lavage fluid. We conclude that there are specialized cells in the ET epithelium expressing and secreting SP-B and propose that SP-B may facilitate normal opening of the tube and mucociliary transport.  (+info)

TY - JOUR. T1 - Effect of the radioprotector WR2721 on irradiation-induced injury to ciliated cells of eustachian tube. AU - Jung, Timothy T.K.. AU - Park, Young Min. AU - Panossian, David. AU - Weeks, Douglas. AU - Miller, Stanley K.. AU - Sandefur, Jere. AU - Krohn, Kenneth A.. PY - 1992/5. Y1 - 1992/5. N2 - Our previous studies revealed that injury to the ciliated cells of the eustachian tube may be the primary cause of irradiation-induced serous otitis media. The purpose of this study was to investigate the effects of the radioprotector WR2721 on irradiation-induced injury to ciliated cells of the eustachian tube (ET) in chinchillas. Twelve chinchillas were divided into two groups: the control group and the experimental group, which was pretreated with a single intraperitoneal dose of the radioprotector S-2-[3-aminopropylamino]ethylphosphorothioic acid (WR2721) 400 mg/kg. The two groups were exposed to 30 Gy of 13-MeV electrons in a single fraction to the area of the bullae and nasopharynx. ...
The middle ear is connected to the other air spaces of the upper respiratory tract via the eustachian tube. The eustachian tube opens periodically during swallowing, yawning, and possibly at times during normal respiration, causing frequent alterations in middle ear pressure. If the eustachian tube remains closed for too long, gas in the middle ear cavity is absorbed slowly and middle ear pressure falls. If middle ear pressure is substantially below nasopharyngeal pressure, mucus in the nasopharynx can be aspirated into the middle ear once the eustachian tube opens. However, negative pressures in the middle ear also may impair the ability of the eustachian tube to open. Upper respiratory infections can cause swelling and edema in the walls of the eustachian tube and hamper the normal function of the eustachian tube. Consequently, in a wide variety of species including the rat, rabbit, guineapig, cattle, and human being, upper respiratory infections often extend to cause otitis media. Eustachian ...
Middle ear and eustachian tube inflammation are common denominators in various clinical conditions, namely, acute otitis media (AOM), chronic otitis media with effusion (COME), and eustachian tube dysfunction (ETD).
This post was originally marked private by mistake. So some of this has changed.. I suffer from a Patulous Eustachian tube. Its an ear disorder where my Eustachian tubes pop open and so when I speak, it sounds as though I am shouting into my own ears (its called autophony). Ive had this problem since 6th or 7th grade, but I never knew what it was called until today. Ive seen a number of doctors about it, even to the point of surgery, but it was never properly diagnosed.. I used to sing and act.. Yes, thats past tense. In high school I was in 4 choirs, and I was always in rehearsal for a play at the local theatre. Its part of why I went to college for film and theatre. I wanted to perform and I wanted to direct performers.. But toward the end of high school, the problems with my ears started to get worse. Projecting my voice became difficult because even speaking at a normal volume is the equivalent of shouting when the tubes are open. So I started seeing doctors and specialists about it. ...

What causes it: The eustachian tube is the tube connecting the middle ear and the upper part of the nasal passages. Eustachian tube dysfunction is a significant factor in the development of otitis media. The purpose of the Eustachian tube is to equalize the pressure on both sides of the ear drum and provide ventilation to the middle ear space. When it does not work properly, the air is trapped in the middle ear space. This air is absorbed and fluid results. Age plays a factor in the development of otitis media. At birth, the eustachian tube is in a horizontal position and it is wider and shorter. During the first few years of life it begins to extend downward allowing for easier drainage. Therefore, otitis media is most common during the first 2 years of life. Inflammation of the nasal end of the eustachian tube may produce swelling, thus impairing its function. Such inflammation may result from viral or bacterial infection (a cold) or chemical irritation (tobacco smoke, chlorinated pool water). ...
Individuals with a eustachian tube problem may experience difficulty equalizing middle ear pressure when flying. When an aircraft ascends, the atmospheric pressure decreases, resulting in a relative increase in the middle ear air pressure. When the aircraft descends, just the opposite occurs; atmospheric pressure increases in the cabin of the aircraft and there is a relative decrease in the middle ear pressure. Either situation may result in discomfort in the ear due to abnormal middle ear pressure compared to the cabin pressure, if the eustachian tube is not functioning properly. Usually, this discomfort is experienced upon descent of the aircraft ...
Swollen or enlarged adenoids can also lead to problems with the ears and hearing. This is because the adenoids can press on the entrance of the Eustachian tubes. Bacteria on the adenoids can also spread up the Eustachian tubes, causing middle ear problems.. The Eustachian tubes connect the middle ear to the back of the nose and help drain away any fluid that builds up in the middle ear, as well as maintaining air pressure within the ear.. When the Eustachian tubes are blocked, fluid can build up in the middle ear, leading to glue ear or a middle ear infection.. If your child cannot hear clearly, it may affect learning, development and social interaction so it is important that ear conditions are diagnosed and treated.. If your childs ear condition is still causing hearing loss after three months, an adenoidectomy may be considered to help the Eustachian tube function normally.. ...

This article describes a relatively little known otologic condition called Patulous Eustachian Tube. The symptoms often go unrecognized since the complaints may, and often do, mimic other ear conditions. This article discusses the assessment, differential diagnosis, and types of treatment currently being utilized for this often challenging condition.
The cause of an ear infection is a virus or bacteria within the middle ear. The infection often comes as a result of another illness, such as allergies, flu, or a common cold. These illnesses cause congestion and swelling of the throat, Eustachian tubes, and nasal passages. The Eustachian tubes are two narrow tubes that goes from the middle ear on each side to the high point in the back of the throat, just behind the nasal passages. The Eustachian tubes at the back of the throat will open and close in order to bring fresh air into the middle ear, regulate the pressure of the air in the middle ear, and drain secretions that are normally in the middle ear. If someone has an illness or allergies, the Eustachian tubes can become inflamed or clogged with mucus. This blockage can allow fluid to build up in the middle ear, leading to the infection of the ear. Children are more susceptible to ear infections partially because their Eustachian tubes are more horizontal and are more narrow. Both of these ...
Air-fluid space is what the middle ear represents. This means there is always some amount of fluid there. But when fluid increases in the ear it generally causes pulsing in ear no matter what was the reason of actual increase. It can be infection, or inflammation, or Eustachian tube dysfunction.. When it comes to chronic inflammation, the blood flow in the middle ear increases especially to the part of the ear that is inflamed and therefore the heartbeat is heard so well - the sensitivity of ear increases.. In a normal healthy state the tubes open and close when a person makes chewing, swallowing, or yawning movements, or while speaking. However in such illnesses as cold and sinusitis, also allergies or excessive earwax the tube gets blocked. This is called Eustachian tube dysfunction and it causes pulsing in ear. All the above mentioned cases of pulsing in ear can be alleviated with antibiotics, decongestants and nasal steroid sprays treatment.. ...

In children the Eustachian tube dysfunction evaluated by impedance audiometer is important to document neutralization of recurrent respiratory papillomatosis definition and negative middle ear pressures. Snoring and obstructive sleep apnea are frequent problems not only in adults, but also in children and adolescents, as can be seen from current epidemiological data. The epidemiological studies illustrated that poor Eustachian tube function plays a major role in the pathogenesis of otits media, so it is very important to have a good function of the tube before and after a surgical procedures.
Our hearing doctors at Audiology by Accent in Gainesville, FL provide hearing care services that are designed to improve your quality of life.
Obstruction or blockage of the eustachian tube results in a negative middle ear pressure, with restraction (sucking in) of the eardrum (tympanic membrane). In an adult this is usually accompanied by some discomfort, such as a fullness or pressure feeling, and may result in a mild hearing impairment and head noise (tinnitus). In children there may be no symptoms. If the obstruction is prolonged, the fluid may be sucked in from the mucous membrane in the middle ear creating a condition called serous otitis media (fluid in the middle ear). This occurs frequently in children in connection with an upper respiratory infection or allergies and accounts for the hearing impairment associated with this condition ...
The majority of ear infections are caused by Eustachian tube. Human inner ear is connected to nasal passages by the Eustachian tube. Its main aim is to stabilize pressure between body and outside environment and also its responsible for draining fluids from ears. As the Eustachian tube is open to adverse bacteria, fluid and mucous, theres no wonder why it can be easily infected.. You dont have to catch cold to get ear infection. Quite often adults have infections simply because of mucous collected in the Eustachian tube. Rhinitis increases the risk of having ear infection. Finally, rare ear cleaning with cotton swab can also cause ear infection. As you can see, ear infections on adults are usually caused by bacteria, not viruses that are more common for children.. The most frequent symptoms for ear infection are pain, pressure or fluid in the infected ear. Sometimes patients notice decrease in hearing that has a timely basis. Usually people become nervous because of hearing loss, but in vast ...

A fairly quite rare case of osseous tumor arising from the Eustachian tube (ET) is described. A 56-year-old man presented with a smooth bulky mass in the nasopharynx and secretory otitis media in the right ear. Computed tomography and magnetic resonance imaging indicated a solid tumor-like region occupying the nasopharynx with apparent extension to the right ET. Transnasal endoscopic surgery demonstrated that the tumor had originated from the ET, and the tumor was partially removed in the area where it had expanded into the nasopharynx. The pathological diagnosis was an osseous hamartoma consisting of bony tissue, fat cells and fibroblasts. To our knowledge, this is the first reported case of osseous hamartoma arising from the ET in the world literature. The patient presented symptoms of nasal obstruction and unilateral aural fullness. Reduction surgery and tympanostomy tube insertion were useful for accurate diagnosis and resolution of the symptoms ...

Q: A day after flying, I start feeling inner-ear pressure and become very ill. My head hurts, and I feel dizzy and so nauseated that I vomit. Some symptoms last six months. My doctor put pressure equalization tubes in my ears, which helped but kept falling out. Now he wants to try larger tubes, but they require general anesthesia. Any advice? - Linda, via email. A: If you fly twice a year, youre spending most of the year feeling sick, so put on your big-girl pants and get a second opinion - as you should with any surgery. When you do, ask about other options, including whether the procedure can be done under a local anesthetic. But lets clarify the problem so everyone knows why youre having this trouble.. When you fly, your ears are subject to wild air-pressure swings. During takeoff, as cabin pressure plummets, pressure builds in your middle ear, where the eardrum is. A little air bubble is released through your eustachian tubes (tiny canals that connect the middle ear to your nose and ...
During ascent, air in the middle-ear space expands, relative pressure increases, the Eustachian tubes open passively, and gas escapes through the Eustachian tubes into the nasopharynx. Occasionally the Eustachian tube may obstruct this flow of air, with subsequent air distension and increased pressure sensation in the middle-ear cavity during ascent. If the obstruction is one-sided and the pressure difference is greater than 60 centimeters of water, vertigo may occur as the pressure increase stimulates the vestibular apparatus. Usually it is relieved by further ascent, because the increasing differential pressure in the middle-ear space forces open the Eustachian tube and vents the excess air. Contributing factors include middle-ear barotrauma during descent, allergies, upper respiratory infections (congestion) and smoking ...

Sep 22, 2018· Assuming you thoroughly understand what eustachian tube dysfunction is, the question now becomes how does one use nasal sprays to correctly treat this disorder. Of note, fluid in the middle ears is treated the same way. Obviously, ear drops will not work because the eardrum prevents anything administered through the ear canal from getting to the eustachian tube which is located BEHIND the ...
There are two theories for the development of a cholesterol granuloma. In the obstruction-vacuum theory, Eustachian tube dysfunction is thought to cause mucosal edema, which can result in repeated episodes of bleeding and subsequent formation of cysts surrounding the blood. The cysts gradually expand.. In the exposed marrow theory, on the other hand, hyperplastic mucosa is thought to invade underlying bone and expose the bone marrow, which, in turn, bleeds.. Either way, a combination of trapped blood and a surrounding chronic inflammatory response lead to the formation of a cholesterol granuloma. In our patient, the etiology is most likely related to Eustachian tube obstruction caused by previous surgery and radiation for a trigeminal schwannoma.. Histologically, cholesterol granulomas contain yellow-brown fluid consisting of cholesterol crystals, red blood cells, and blood break-down products.. Cholesterol granulomas are surrounded by a fibrous tissue capsule and can be located in any part of ...
Adverse reactions of HBO2 therapy are rare and largely unique to the hyperbaric environment. Pressure affects gas-filled spaces: Specifically, as the pressure around a gas-filled space increases, its volume will decrease, and vice versa. This inverse relationship between pressure and volume is known as Boyles Law.2 The human body has several gas-filled spaces, all of which are vulnerable to barotrauma, or pressure-related injury, if these spaces fail to equalize with the changing ambient pressure in the hyperbaric chamber.. The middle ear, the area most commonly affected by barotrauma, is connected to the nasopharynx via the eustachian tube.2 The eustachian tube helps modulate pressure in the middle ear by allowing air to pass into and out of the middle ear during changes in ambient pressure. Patients may have difficulty equalizing the middle ear pressure during hyperbaric therapy if they have anatomic variations or a eustachian tube thats been narrowed by radiation-induced stenosis or ...
When rapid ambient pressure increase occurs as in diving or aircraft descent, this pressure tends to hold the Eustachian tubes closed, preventing pressure equalization across the ear drum, with painful results.[4][5][6] To avoid this painful situation, divers, caisson workers and aircrew attempt to open the Eustachian tubes by swallowing, which tends to open the tubes, allowing the ear to equalize itself. If this fails, then the Valsalva maneuver may be used. This maneuver, when used as a tool to equalize middle ear pressure, carries with it the risk of auditory damage from over pressurization of the middle ear.[1][5][7][8] It is safer, if time permits, to attempt to open the Eustachian tubes by swallowing a few times, or yawning, or by using the Valsalva technique of breathing a very small amount of air gently into nostrils held closed by the fingers as soon as mild pressure is felt, before it increases to the point that its release would be painful. The effectiveness of the yawning method ...
The endoscopic images in Figure 1 and 2 are that of a normal guttural pouch in a horse. There are 2 guttural pouches in the horse and their role is not clearly defined. However, there are several very important structures which course through the guttural pouches. These include large veins and arteries plus critical cranial nerves (Figure 2) . Each guttural pouch is divided into a medial and lateral compartment by a unique bone named the stylohyoid bone. This bone articulates with the base of the skull, just below the ear drum and is part of the support structure for the tongue and larynx! As such, when the horse moves its tongue the articulation between the stylohyoid bone and the base of the skull moves as well. The large blood vessels located within the guttural pouch are important for bringing oxygenated blood to the brain and draining deoxygenated blood from the brain. Equally important are the cranial nerves that course through the guttural pouches. These nerves are essential for a proper ...
Acute otitis media is an infection of the middle ear and Eustachian tubes. It can occur at any age, but primarily affects children between the ages of six months and two years. The condition is very common: Thirty percent of all antibiotics given to children are prescribed for otitis media, and the incidence has been rising over the last 25 to 30 years.. The most common cause is an upper respiratory infection. As the Eustachian tubes of the middle ear become congested and obstructed, infection begins. Another cause is allergies, which can cause dysfunction of the Eustachian tubes ...
The middle ear is normally an air-filled space deep to the ear drum. The pressure in the middle ear is equalized to the atmospheric pressure through the Eustachian tube. The Eustachian tube would open and close when we swallow or yawn. When there is poor function of the Eustachian tube, negative pressure will develop in the middle ear which leads to fluid accumulation ...
The Eustachian tube is a narrow structure running between the air-filled middle ear space and the back of the nose. It is designed to allow ventilation of the middle ear, but in around 5% of the adult population, the tube fails to open adequately, causing many different types of ear disease. Balloon Eustachian Tuboplasty (BET) is a new minimally-invasive technique using a narrow balloon to stretch the Eustachian tube and has recently been used in patients. The aim of this project is to study the biomechanics of balloon inflation within human Eustachian tube tissue. In parallel, physical and 3D computer-based models will be created to add to our clinical observations, and provide methods of testing innovative adaptations to the procedure, and new equipment modifications. The project is a collaboration with Matt Smith and James Tysome in the ENT Department at Addenbrookes Hospital, with the help of a Engineering for Clinical Practice grant undertaken by MEng students Daisy Prior and Anna Weir ...
A clogged ear is a telltale sign of blocked Eustachian tubes. Eustachian tubes are located in the middle ear; they regulate air pressure and protect your ear drum from foreign objects. When the air pressure is significantly changed, your Eustachian tubes expand to prevent damage, which creates a muffled effect. According to the Mayo Clinic, swollen nasal passages also contribute to a clogged ear, as fluid becomes trapped in the middle ear. Medications may be required to reduce inflammation and provide relief. However, there are also home remedies that aid the healing process.. ...

Earlier I wrote about Sir Astley Cooper and his procedure of tympanic membrane perforation as a remedy for deafness. While in Britain there wasnt tremendous grounds being made in aural surgery, the situation was quite different in France, as surgeons made more advancements in Eustachian tube catheterization as a remedy than their British counterparts. By the…
The levator veli palatini is a muscle of the human body. During swallowing, it contracts, elevating the soft palate to help prevent food from entering the nasopharynx. It is innervated via the pharyngeal plexus, primarily by the vagus nerve (CN X). The Levator veli palatini (Levator palati) is a thick, rounded muscle situated lateral to the choanæ. It arises from the under surface of the apex of the petrous part of the temporal bone and from the medial lamina of the cartilage of the auditory tube. After passing above the upper concave margin of the Constrictor pharyngis superior it spreads out in the palatine velum, its fibers extending obliquely downward and medialward to the middle line, where they blend with those of the opposite side. ...
There are many potential causes of conductive hearing loss, with some problems being easier to treat than others. This type of hearing loss may be indicative of something more serious, such as a tumor on the hearing nerve, or something relatively easy to remedy, such as an earwax blockage in the ear canal. Malformation of the outer or middle ear structures, a middle ear infection in which fluid accumulates behind the eardrum, abnormal bone growth in the middle ear, a hole in the eardrum, or poor Eustachian tube function may be responsible for conductive hearing loss.. ...
Typically, otosclerosis progresses to the stapes, the ultimate transducer of the middle ear chain. The stapes are held in place by a small groove known as the oval window, directly touching the inner ear fluids. Conductive hearing loss happens when an object impairs the movement of the ear. The medical word for this condition, which is typically treatable surgically, is stapedius otosclerosis.. This study aimed to ascertain the chorda tympani nerves function before and following various forms of middle ear surgery. The hypothesis was that iatrogenic nerve injury would result in a milder postoperative taste disturbance than myringoplasty or stapedectomy in cholesteatoma patients. This study employed a prospective questionnaire method. The setting is set in the emergency room of a district general hospital in the United Kingdom. Patients aged 18 years and older receiving surgery to raise the middle ears annulus.. Often, the procedure is performed as an outpatient. Certain patients may require a ...

The palatopharyngeus (palatopharyngeal or pharyngopalatinus) muscle is a small muscle in the roof of the mouth. It is a long, fleshy fasciculus, narrower in the middle than at either end, forming, with the mucous membrane covering its surface, the palatopharyngeal arch. It is separated from the palatoglossus muscle by an angular interval, in which the palatine tonsil is lodged. It arises from the soft palate, where it is divided into two fasciculi by the levator veli palatini and musculus uvulae. The posterior fasciculus lies in contact with the mucous membrane, and joins with that of the opposite muscle in the middle line. The anterior fasciculus, the thicker, lies in the soft palate between the levator and tensor veli palatini muscles, and joins in the middle line the corresponding part of the opposite muscle. Passing laterally and downward behind the palatine tonsil, the palatopharyngeus joins the stylopharyngeus and is inserted with that muscle into the posterior border of the thyroid ...

Ear infections (acute otitis media) occur in the space behind the eardrum, which is called the middle ear. Ear infections are more likely to occur after a cold or other upper respiratory infection has been present for a few days.During a cold, throat infection, or allergy attack, the tube that connects the throat and the middle ear (eustachian tube) swells and prevents air from entering the ...
One of the most common childhood infections, Otitis media is the leading cause of visits to the doctor by children. It is also the most frequent reason children receive antibiotic prescriptions or undergo surgery. In order to fully understand otitis media, it is helpful to have a basic knowledge of ear anatomy. Deep within the outer ear canal is the eardrum, which is a thin, transparent membrane that vibrates in response to sound. Behind the eardrum is the space called the middle ear. When the eardrum vibrates, three tiny bones within the middle ear, called ossicles, transmit these sounds to the inner ear. Nerves are stimulated in the inner ear, which then relay the sound signals to the brain. The eustachian tube, which connects the middle ear to the nose, normally equalizes pressure in the middle ear, allowing the eardrum and ossicles to vibrate correctly, so that hearing is normal. There are certain factors particular to children that make them more at risk for otitis media. In children, the ...
The tympanic membrane or eardrum is a thin membrane that separates the outer ear canal from the middle and inner ear. The middle ear contains the three tiniest bones in the body, the malleus, incus and stapes, more commonly referred to as the hammer, anvil and stirrup. The Eustachian tubes are also located in the middle ear. If the eardrum is perforated or tears, bacteria and fungi from the outer ear canal may enter the sensitive middle ear resulting in otitis media or middle ear infection. ...
Upper respiratory tract infection. Illustration of a human head with cutaway areas showing the processes involved in an upper respiratory tract infection (URTI). Examples include rhinitis (inflamed nasal membranes). The conditions shown here are inflammation of the paranasal sinuses (sinusitis), and a middle ear infection (otitis media). Mucus (yellow) is seen accumulating and flowing within the sinuses, and in the middle ear and the Eustachian tube (connecting the ear to the throat). The cochlea (pink) is shown in the ear. The frontal sinus is at top (in the forehead), the ethmoidal sinuses are between the eyes, and the maxillary sinuses are in the cheekbones. - Stock Image C029/0642
Myringotomy in Littleton: Placement of tympanostomy is one of the most common surgical procedures in the U.S. In the normal middle ear, air passes from the back of the nose through the eustachian tube and provides ventilator airflow to the middle ear.
Doctors help you with trusted information about Ear Infections in Ear Infection: Dr. Furst on hearing loss caused by ear infection: First, make sure that infection completely gone, that sinuses and mastoids are clear, and eustachian tube is fully patent. Also, check that no cerumen is blocking external auditory canal. Get updated audiogram to objectify your ability to hear, and if there is severe issue, modern hearing aides would really help.

The ear consists of the external ear canal, middle ear, and inner ear. The middle ear is separated from the ear canal by the eardrum. The middle ear contains the malleus, incus, and stapes, which are also known as the hammer, anvil, and stirrup. The inner ear contains the cochlea, which is the main sensory organ of hearing. The Eustachian tube runs from the middle ear to the area in back of the nose.. ...
Strangles can take an unusual course with multiple small or single large abscesses (as large as a dinner plate!) forming in the chest and abdomen. This is often termed bastard strangles and can be very difficult to diagnose and treat successfully. Euthanasia may be the only humane option.. Occasionally a horse becomes a long-term subclinical carrier of the disease, (months to years), but does not display outward signs. Usually the bacteria are hiding in the guttural pouches, (two empty sacks that sit behind the jaw), and pus may be present when investigated with a scope. They will also test positive with laboratory samples. When chronic carriers remain undiagnosed, it is usually these animals that continue the cycle of reinfection in horse populations. Often these carriers only spread the infection when they are stressed, e.g. transported or at foaling. To stop these horses continually shedding into the environment, the infection must be cleared from the guttural pouches. Until cleared, ...
Streptococcus equi, a highly contagious and specialized bacterium, causes abscessation of lymph nodes (strangles) in horses. Acute infections and chronic complications, such as abdominal abscesses, accumulation of purulent material in the guttural pouch, and airway obstruction occur in about 20% of the cases, leading to sustained loss of performance and animal health and can even be fatal. All breeds are affected and infection seems to be maintained in the population through chronically infected carriers, which harbor the organism in their guttural pouches from where bacteria are intermittently shed. Once S. equi abscesses have formed, antibiotics have reduced efficacy, are generally not indicated, and can even lead to exacerbation of disease. Symptomatic therapy such as anti-inflammatory drugs and lancing of abscesses are often the only option. Adjuvanted intramuscular S. equi vaccines often cause muscle soreness and injection site abscesses, while commercial intranasal vaccines (modified live) ...
The experience of popping ears when flying on an airplane is the most common medical complaint of airplane passengers. Due to an air pocket in the middle ear that is sensitive to air pressure changes, the changing altitude as the plane takes off or lands can cause discomfort in the ears.. Swallowing or yawning usually can help pop the ears (activating the muscle that opens the Eustachian tube, which connects the middle ear with the nasopharynx) and ease the discomfort. However, ears that are already blocked (by a cold, for example) cannot equalize the air pressure in the middle ear adequately, therefore, creating a vacuum that sucks the eardrum in and stretches it. When the eardrum cannot vibrate, sound is muffled and the stretched eardrum can be very painful.. If swallowing or yawning does not relieve the ears, the American Academy of Otolaryngology recommends trying the following ear-clearing technique:. ...
If the air pressure outside the ear quickly increases then this pushes the eardrum inwards which can be painful. The tensed eardrum also cannot vibrate as well as it should and so you may also have dulled hearing. To relieve the tensed eardrum, the pressure inside the middle ear has to rise quickly too. Air needs to travel up the Eustachian tube into the middle ear to equalise the pressure.. The most common example of barotrauma affects some air travellers. As a plane descends to land, the air pressure becomes higher. This pushes the eardrum inwards. If the pressure inside the middle ear is not equalised quickly then you can get ear pain. Other situations where air pressure may quickly rise outside the ear are during scuba diving, diving to the bottom of a swimming pool, or rapidly descending in a lift (elevator).. ...
Common causes of temporary hearing problems that people regularly report is an infection in the middle ear. It is usually not easily recognized until you become irritated by the pain. Sometimes a high fever can develop as well. People often worry that this infection can become chronic and cause hearing loss.. The Eustachian tubes, which run from the ears to the throat, help maintain air pressure in the middle ear and drain fluids. However, they are also the easiest way for throat infections to get to our ears. Because these tubes are too small, the swelling caused by the infection impedes drainage. Doctors usually prescribe antibiotics to help treat the condition.. There are many natural solutions to treat this type of infection. A special oil preparation made from mullein flowers and garlic can help reduce inflammation in the ears, kill bacteria and help relieve pain. Garlic also helps with any fungal infection that occurs in the outer ear. Ear oils made from St. Johns wort and calendula can ...
It is vital that the ossicles can move freely, and that the pressure on both sides of the ear drum is the same (otherwise it would be pushed in or out too far). There is an important channel that runs from the middle ear to the throat that helps keep the air pressure the same, when air-pressure changes. This is the eustachian tube. (Its odd that we should have the evolutionary equipment to cope with pressure changes, when weve only just learned how to go up in lifts and aeroplanes, and down mine shafts. Perhaps the people who claim we evolved in the water are right. When you dive, the pressure changes on your ears and you need someway to equalise this). The last ossicle (the stirrup) is attached to the oval window in the cochlea. The area from the ear drum to the oval window is called the middle ear.. The cochlea is the inner ear. It has an oval window, that is in contact with the stirrup. It is a shell-shaped organ. Below the oval window, there is another, round window. When the stirrup ...
Tilt your head slightly back towards the side of the left or the right ear, depending on whether you have used the right or the left nostril respectively. This allows the spray to come into contract with the opening of the eustachian tube, offering protection from acute otitis media and infections of the inner ear.. ...
When the eustachian tube in your middle ear is blocked due to altitude or pressure changes (barotrauma), air cannot be equalized, and a vacuum occurs.

Barotrauma is tissue damage due to differences in pressure in the body with the air pressure around it. The most common Barotrauma is Ear Barotrauma. The condition occurs when the eardrum becomes tense and attracted due to differences in pressure inside and outside the ear. Under normal circumstances, the air pressure on both sides of the eardrum should be the same, so that it can function properly. Air pressure regulator in the ear is played by an eustachian tube that is behind the eardrum. When the tube is blocked, there is a difference of pressure on the inside and outside of the ear, so that there is barotrauma. Barotauma is characterized by a distressed eardrum or stretched so that the ears are painful and clogged so that hearing will be reduced ...

It is critical for designing shallow geothermal systems to accurately estimate thermal properties of soil and backfilling material. This paper reports on a new algorithm for simultaneously estimating thermal conductivities and diffusivities of soil and backfilling material. The algorithm uses a 2D composite-medium line-source solution for borehole ground heat exchangers, enabling early-time (,10 hr) data of thermal response tests (TRTs) to be used in the parameter estimation. The new algorithm is validated by a reference sandbox experimental data. Several theoretical issues of parameter estimation were explored, including sensitivity, identifiability, and uncertainty. The key findings of this study are: (1) the early-time data of TRTs can greatly reduce the linear dependence of the estimated parameters and thus improve the identifiability of the parameter estimation. (2) The accuracy of the estimates, ranked in descending order are as follows: soil thermal conductivity ks (±2%), grout thermal ...
Normal procedure is to evaluate the horse with or without sedation depending on the initial complaint. After the horse is sedated, a local anesthetic is sprayed up the nasal cavity to numb the area. The endoscope is passed through the nostril and is fed up the nasal cavity along the floor of the ventral meatus. By watching the monitor, the endoscope is manoeuvred up the nasal cavity and around guttural pouches, larynx, nasopharynx and upper trachea. It can be used to detect areas of inflammation, excessive mucus production or a defect such as roaring (laryngeal paralysis).. ...

This disease can be picked up by changes in the ratio between sodium or potassium by accident at times. When this happens it is still extremely important to treat for it. It is confirmed by an ACTH response test -- administration of this hormone should stimulate production of adrenal hormones. If this does not occur then hypoadrenocorticism is present. In cases in which the electrolyte levels are normal this is the only test for the problem and it will be missed unless it is looked for specifically. At times this disease can be hard to differentiate from renal failure because the symptoms and even the bloodwork can be similar ---- so the ACTH response test may be necessary to differentiate them ...
Natural News) Just like Eve who was lured into taking a bite out of the forbidden apple in the Garden of Eden, many people today are enamored with the idea of chomping down on anything that tech giant Apple throws their way.

At length, the guttural mooing and neighing of mutant seal-ponies, the result of some forgotten experiment in genetic modification aimed at supplying marine meat to the Dutch, indicated that land was near. I could only hope that the Giant Cod-Orca, predator of the strange seal-pony, was not an early visitor to these waters. In the main, come summer the Cod-Orca schools moved towards easier pickings among the humans to be found bathing for their health in the spa waters from the old Hunterston F nuclear station. How laughable it seems now that irradiated water was once thought harmful! Now its healing properties have become an obsession among the poor humans vulnerable to ultraviolet light. Epidermal damage from the ozone layers depletion reached epidemic proportions, of course, before Avon-BMW developed their gene therapy Skin-So-Soft bio-germ molecular alteration lotion.

Melbournes blast beat merchants Doubled Over had been notably dormant for a number of years, perhaps even totally dispatched until recently reforming to make a contribution to this split 7 with Cleveland grind stalwarts, Hemdale. Perhaps naively, Hemdale arent a band that I had ever been familiar with before this record came about, but research shows a 20 year history of demos, split release and the like, and talk of an ill fated LP that never saw the light of day. They play a pretty solid blend of no frills grind, generally the kind that I am normally most fond of. Perhaps I need to track down this bands other stuff. Doubled Over strike back with their style of obtrusive, straight forward grind. Guttural bellows dominate the mix, and as always Christophs percussion is world class. Lineage and influence of course can be traced back to bands like Excruciating Terror and perhaps even their split mates here. Pressed by Fat Ass Records ...
