To explore the feasibility of constructing a proof-of-concept artificial intelligence algorithm to detect tympanic membrane perforations, for future application in under-resourced rural settings. Methods A retrospective review was conducted of otoscopic images analysed using transfer learning with Googles Inception-V3 convolutional neural network architecture. The gold standard ground truth was defined by otolaryngologists. Perforation size was categorised as less than one-third (small), one-third to two-thirds (medium), or more than two-thirds (large) of the total tympanic membrane diameter. Results A total of 233 tympanic membrane images were used (183 for training, 50 for testing). The algorithm correctly identified intact and perforated tympanic membranes (overall accuracy = 76.0 per cent, 95 per ...

Drop weld injuries to the tympanic membrane and middle ear caused by hot sparks or molten slag are a rare but significant injury. Steel workers and welders who are regularly exposed to flying sparks and molten metal slag are predisposed. This type of transtympanic thermal injury occurs when the slag literally drops into the external auditory canal and burns through the tympanic membrane. A spectrum of severity of injury occurs which includes chronic tympanic membrane perforation, chronic otorrhoea, facial nerve injury and deafness. Chronic tympanic membrane perforation is the most common sequelae and is perhaps one of the most challenging of all perforations to repair The combination of direct thermal injury and foreign body reaction results in continuing or recurrent suppuration. The foreign body reaction is due to the embedding of metal slag in the promontorial mucosa. We present a case of drop weld injury to the left tympanic membrane, resulting in chronic middle ear inflammation, otorrhoea ...
The eardrum can have a hole or defect present from a variety of reasons including trauma or a severe infection can result in a perforation of the eardrum.
Hypothesis: Type II collagen is synthesized in the tympanic membrane during healing of a perforation. The time course and appearance of Type II collagen regrowth in the newly healed tympanic membrane is the subject of the present study. Background: The arrangement of Type II collagen fibers in the tympanic membrane gives it a unique tensile strength important for sound conduction. Healing after tympanic membrane perforation can cause the tympanic membrane to lose its characteristic. At what phase Type II collagen in tympanic membrane is replaced during healing of a perforation has previously not been studied. Methods: Rat tympanic membranes were perforated, and the animals were sacrificed 9 to 16 days after perforation. Tympanic membranes were stained with a Type II collagen antibody. Results: At Day 9, a majority of the tympanic membranes had healed. Keratinizing epithelium and connective tissue had formed, but there was no Type II collagen. At Day 10, all tympanic membranes had healed, and ...
Introduction. Tympanoplasty is one of the surgeries most frequently performed by otorhinolaryngologists for the correction of tympanic membrane perforations and the reconstruction of the mechanism of sound transmission in the middle ear. The graft used, such as a temporalis muscle fascia, functions as a support on which epithelialization currents slide in order to repair a perforation of the tympanic membrane1. Preliminary retrospective studies have indicated greater vascularization of tympanic membrane grafts when a natural latex membrane is used as a transitory implant in tympanoplasty2. A natural biomembrane prepared with latex extracted from the rubber tree Hevea brasiliensis and polymerized with 0.1% polylysine was developed by the Department of Biochemistry of the Faculty of Medicine, of Ribeirao Preto, University of Sao Paulo. The membrane was used experimentally as a cicatrization-inducing material on the injured esophageal walls of dogs and was shown to lead to a marked increase in ...
Table 2 of the article "Topical Fluoroquinolones for Eye and Ear" (October 15, 2000, page 1872) contained an error regarding the recommended use of the topical medication ciprofloxacin-hydrocortisone (Cipro HC). The table incorrectly states that Cipro HC, a nonsterile solution, is recommended for use in patients with acute otitis externa and acute otitis media with tympanic membrane perforation. According to the 55th edition of the Physicians Desk Reference, the use of Cipro HC is actually contraindicated in patients with a perforated tympanic membrane. However, the table correctly indicates that Floxin, a 0.3 percent sterile solution of ofloxacin, is indicated for use in patients with acute otitis externa, chronic suppurative otitis media with perforations and acute otitis media with tympanostomy tubes. The corrected table is reprinted above. ...
This systematic review included randomised controlled trials (RCTs) focused on patient-relevant outcomes. Primary outcomes were the proportion of children with: (1) pain at 1, 2-3, 4-7 and 10-14 days, and (2) adverse effects (vomiting/diarrhoea/rash). Secondary outcomes included abnormal tympanometry, tympanic membrane perforation, contralateral AOM, complications of AOM and long-term healthcare utilisation. Searches were undertaken in a litany of databases, and independent extraction was performed. Study quality was assessed according to possible allocation/performance/attrition/other biases; a grading of recommendation ...
Topical fluoroquinolones are now available for use in the eye and ear. Their broad spectrum of activity includes the common eye and ear pathogens Staphylococcus aureus and Pseudomonas aeruginosa. For the treatment of acute otitis externa, these agents are as effective as previously available otic preparations. For the treatment of otitis media with tympanic membrane perforation, topical fluoroquinolones are effective and safe. These preparations are approved for use in children, and lack of ototoxicity permits prolonged administration when necessary. Topical fluoroquinolones are not appropriate for the treatment of uncomplicated conjunctivitis where narrower spectrum agents suffice; they represent a simplified regimen for the treatment of bacterial keratitis (corneal ulcers). When administered topically, fluoroquinolones are well tolerated and offer convenient dosing schedules. Currently, bacterial resistance appears limited.
Interactions between the immune response and brain functions such as olfactory, auditory, and visual sensations are likely. This study investigated the effect of sounds on alloimmune responses in a murine model of cardiac allograft transplantation. Naïve CBA mice (H2k) underwent transplantation of a C57BL/6 (B6, H2b) heart and were exposed to one of three types of music--opera (La Traviata), classical (Mozart), and New Age (Enya)--or one of six different single sound frequencies, for 7 days. Additionally, we prepared two groups of CBA recipients with tympanic membrane perforation exposed to opera for 7 days and CBA recipients exposed to opera for 7 days before transplantation (pre-treatment). An adoptive transfer study was performed to determine whether regulatory cells were generated in allograft recipients. Immunohistochemical, cell-proliferation, cytokine, and flow cytometry assessments were also performed. CBA recipients of a B6 cardiac graft that were exposed to opera music and Mozart had

Figure 3. Periapical X-Rays of implant placed using BAOSFE technique, prior to surgery and 6 months post-surgery.. (3,4) Recently, a systematic review of the literature showed that crestal sinus lift can be an effective treatment option, reporting a mean weighted survival rate of 95% after 5 years of function. (26) The same review also showed that the majority of failures occurred during the first year after treatment. However, limitations of this procedure include: limited accessibility and visibility for elevation of the sinus membrane and inability to diagnose and treat membrane perforations. (27,28,10) When the membrane is lifted more than 3 mm, the risk of membrane perforation increases significantly. (29,30) The use of an endoscope has been proposed to diagnose the membrane perforation during BAOSFE, increasing the cost and time of the procedure. (29,30) Thus, in cases where crestal height is 4-7 mm and an implant length of 10-13 mm is desired, the sinus membrane will be lifted greater ...

Endoscopic observations. For 85 patients without edge approximation, the inverted or everted eardrum became black during the spontaneous healing process within 3 days. Thereafter, the black everted eardrum gradually increased, and the inverted or everted eardrum became completely black and formed a crust in the Type I cases on days 4-5. The inverted or everted eardrum formed a complete crust in Type II and Type III cases on days 5-7. Proliferation and migration of the epithelium occurred simultaneously and increased gradually over time. Additionally, in the drooping eardrum cases, there was gradual shrinkage along the perforation edge and a crust formed over time (Fig. 3). The crust migrated gradually toward the EAC.. In the 63 patients with edge approximation, the perforation size reduced to ∼20-50% in 41 patients and ,50% in 22 patients after edge approximation. The repaired eardrum had not obviously changed on day 2; the morphology of the inverted or everted edge was similar to that prior ...

A different tenor underlay the description of images from the individual measurements. It states: "Images show either only Ga atoms, or only As atoms." (Feenstra et.al. 1987, p. 1193). In this interpretation, only atoms that appear in the image as maxima are visible. Heinrich Rohrer, as well, referred to these measurements in a review article, writing: "As appears in the image of the occupied states, Ga in those of the empty states." (Rohrer 1990, p. 12) Consequently, a minimum, which also arises by keeping the tunneling current between the tip and the individual atom constant, does not show an atom, an atom does not appear. All participants were, of course, theoretically aware that electronic properties determined the trace of the tip and that the minima could be matched to the position of atoms. Nonetheless, even in professional publications they developed a language that deviated from this knowledge and that reserved the visibility of atoms for the appearance of maxima. Here the expectation ...

TY - JOUR. T1 - Endoscopic transcanal myringoplasty for tympanic perforations. T2 - An outpatient minimally invasive procedure. AU - Tseng, Chih Chieh. AU - Lai, Ming Tang. AU - Wu, Chia Che. AU - Yuan, Sheng Po. AU - Ding, Yi Fang. PY - 2017. Y1 - 2017. N2 - Objective: Since the 1950s, microscopic myringoplasty has been the standard surgery for repairing a perforated tympanic membrane. In addition to conventional microscopic myringoplasty, endoscopic myringoplasty has been an emerging technique since the late 1990s. This study evaluated the efficacy of endoscopic transcanal myringoplasty for repairing tympanic perforations and examined the minimally invasive feature of this technique (no postauricular incision, no canalplasty). Methods: We retrospectively reviewed the medical records of patients who underwent endoscopic transcanal myringoplasty for perforations of the tympanic membrane. The main outcome was the overall rate of graft success of endoscopic transcanal myringoplasty. Results: A ...

2Mehmet Akif Inan Training and Research Hospital, Otorhinolaryngology, Şanlıurfa, Turkey Objectives: To investigate the differences between endoscopic and microscopic butterfly cartilage tympanoplasty.. Material and Methods: Eighty-seven patients under endoscopic and microscopic butterfly cartilage tympanoplasty was done. Mean audiometric results were evaluated among the groups before surgery and six months after surgery at 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz at air and bone conduction thresholds. Air conduction pure tone audiometry (PTA), air-bone gap reduction, air-bone gap (ABG) and hearing gain before and after surgery were calculated after surgery.. Results: No statistically significant difference was found between the groups respectively in terms of the mean ABG before and after surgery (24.9±7.5 dB vs. 23.7±6.5 dB; 16.7 dB ± 5.2 vs. 15.9 dB ±5.8dB). Both groups showed significantly lower ABG after surgery than that before surgery ( ...
TY - JOUR. T1 - Revision tympanoplasty utilizing fossa triangularis cartilage. AU - Moore, Gary Floyd. PY - 2002/9. Y1 - 2002/9. N2 - Objectives/Hypothesis: A small percentage of fascia graft tympanoplasties fail. Cartilage tympanoplasty has a reputation for excellent graft healing but potentially sacrifices maximum hearing improvement and creates difficulty in postoperative follow-up resulting from opacity and immobility. We sought to use a tissue thicker than fascia but thinner than tragal cartilage to repair tympanic membranes that had failed previous fascia grafting. Our hypothesis was that use of the thinner cartilage would maintain the excellent healing rate and resistance to chronic negative pressure while improving hearing and mobility. Study Design: The study is a retrospective review of all patients who received a total cartilage graft tympanoplasty after experiencing a failed standard fascia graft tympanoplasty. No previous operative series on impedance testing following cartilage ...

Hello all. Maybe someone can help me. I had a myringoplasty performed on my left ear 7 weeks ago. A day or two after the surgery I had severe breathing difficulty or the sensation of my airway swelling shut. Only until 4 days ago has it begun to progressively get better, however, I still experience breathing problems. Im not sure if I had any nerve trauma, muscles in the neck twisted due to a flacid body under general anesthesia during surgery. Ive certainly had some soreness and swelling on the left side extending from the ear to the base of the neck. The swelling has gone down, but I still get the sensation that I have to force O2 into my body for adequate perfusion. Sometimes I feel my airway is cut off in the throat and/or something is stuck creating a pressure sensation that, again, makes it difficult for me to breath. At times I can adjust my body positioning to see if that opens the airway a bit more and once in awhile it seems to help. Ive recently been to a Chiropractor (friend) who ...

TY - JOUR. T1 - Hormonal and environmental interactions on thyroid function in the chick embryo and posthatching chicken. AU - Kuhn, E. R.. AU - Decuypere, E.. AU - Rudas, P.. PY - 1984. Y1 - 1984. N2 - Recent research has focused on developmental changes in thyroxine (T4) metabolism as well as hormonal and environmental interactions upon peripheral monodeiodination. Toward the end of incubation and the time of air space membrane perforation, concentrations of 3,3,5-triiodothyronine T3 increase more rapidly than T4, while reverse T3 (rT3) decreases. Administration of glucocorticoids or prolactin (hormones known to increase at the end of incubation) 2 to 3 days prior to air chamber perforation can induce this change in T4 metabolism. Attention has been focused on 2 major environmental factors that influence T4 concentrations in posthatch chicks. T4 disappearance rate and peripheral T4 conversion are adjusted during thermal acclimation. More T3 will be generated in cold-exposed chickens, and ...
