The superior laryngeal nerve is a branch of the vagus nerve. It arises from the middle of the inferior ganglion of vagus nerve and in its course receives a branch from the superior cervical ganglion of the sympathetic nervous system. All intrinsic laryngeal muscles except the cricothyroids are innervated by the recurrent laryngeal nerve. The cricothyroid muscles are innervated by the superior laryngeal nerve. The superior laryngeal nerve consists of two branches: the internal laryngeal nerve (sensory), which supplies sensory fibers to the laryngeal mucosa, and the external laryngeal nerve (motor), which innervates the cricothyroid muscle. The recurrent laryngeal nerve gets its name from the fact that it loops below the aorta on its way to the intrinsic muscles of the larynx. The left recurrent laryngeal nerve passes under and around the aorta on its way to the larynx, whereas the right recurrent laryngeal nerve passes under and around the subclavian artery. Because the aorta is inferior to the ...

Thyroid disorders affect millions of people worldwide. In many cases, surgical treatment is necessary and often the only solution. For example, where a goitre, an enlargement of the thyroid gland, has formed, or if malignant changes are found, surgical intervention is recommended.. In the case of surgical intervention where partial removal of the thyroid gland (subtotal thyroidectomy) or its complete removal (total thyroidectomy) is required, these procedures carry a risk of damage to the vocal cord nerve, the recurrent laryngeal nerve. If the recurrent laryngeal nerve is impaired or damaged, this can have serious consequences for the patient. Impairment or damage to the recurrent laryngeal nerve can result in short-term hoarseness after surgery or even lead to permanent bilateral vocal cord paralysis.. Intraoperative neuromonitoring during thyroid surgery enables the function of the recurrent laryngeal nerve to be monitored throughout. The continuous monitoring process enables the surgeon to ...

RATIONALE: Recurrent laryngeal nerve block is an uncommon complication that can occur after an interscalene brachial plexus block (ISB), which may lead to vocal cord palsy or paresis. However, if the recurrent laryngeal nerve is blocked in patients with a preexisting contralateral vocal cord palsy following neck surgery, this may lead to devastating acute respiratory failure. Thus, ISB is contraindicated in patients with contralateral vocal cord lesion. To the best of our knowledge, there are no reports of bilateral vocal cord paresis, which occurred after a continuous ISB and endotracheal intubation in a patient with no history of vocal cord injury or surgery of the neck ...

The larynx is composed of nine cartilages, three paired and three unpaired and these cartilages contain within them the vocal cords. The movements of the larynx are controlled by the extrinsic muscles which move the larynx as a whole and the intrinsic muscles which move the various cartilages in relation to one another. The larynx is innervated bilaterally by the superior laryngeal nerve (supplies mucosa from the epiglottis to the level of the cords) and the recurrent laryngeal nerve (supplies mucosa below the cords), both branches of the vagus nerve (CN X). The recurrent laryngeal nerves supply all of the intrinsic muscles of the larynx except for the cricothyroid muscle and any damage to the recurrent laryngeal can result in vocal cord dysfunction. The cricothyroid muscle is innervated by the external branch of the superior laryngeal nerve.. Other nerves which may need to be anesthetized for awake fiberoptic intubations include the maxillary branch of the trigeminal nerve which supplies ...

This is because recurrent laryngeal nerve palsy will lead to paralysis of all laryngeal muscles except the cricothyroid muscle (as it is supplied by superior laryngeal nerve). The cricothyroid muscle is an adductor & therefore this will leave both the cords in median or paramedian position thus endangering proper airway, leading to stridor and dyspnoea. Trauma due to thyroidectomy is the most common causes. ...

We have developed a combined surgical technique involving traction sutures, the harmonic scalpel, and laryngeal nerve monitoring for the removal of mediastinal goiters. This technique is safe, expeditious, and effective; it minimizes the risk of blood loss or nerve injury; and it obviates the need for sternotomy. During a 4-year period, we performed this operation on 21 patients. We observed only two complications: one patient developed postoperative seroma 1 week after surgery and another experienced vocal fold paralysis after intentional sacrifice of the recurrent laryngeal nerve, which was encompassed by cancer. No other recurrent laryngeal nerve was injured. Operative blood loss was negligible, no systemic infection or permanent hypoparathyroidism was observed, and no patient required a chest tube or chest incision. Almost all patients were discharged home on postoperative day 1. ...

N2 - The Da Vinci Surgical System was developed to overcome some of the disadvantages of conventional endoscopic surgery. We have been performing robotic gastrectomy or esophagectomy in patients with resectable gastric or esophageal cancer who agreed to uninsured use of the robot since 2009, resulting in reduced postoperative local complications including pancreatic fistula following gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. Moreover, the greater the extent of resection and lymph node dissection, the greater this effect, suggesting that the robot may be more beneficial for advanced cancer than for early cancer. In the meantime, there have been a considerable number of reports, mostly focusing on early cancer, that the use of the robot may reduce cost-effectiveness in comparison with the conventional laparoscopic or ...

Prof Jean Paul Marie has developed a new surgical technique, in which both the functions of voice and breathing difficulty are corrected. This is known as the laryngeal reinnervation procedure and consists of transferring the root of the nerve to the diaphragm( muscle separating chest and abdomen) to the laryngeal muscle. In addition a small branch of the nerve to the tongue is also attached to the voice box muscle so as to improve the speaking voice. Dr Jayakumar Menon, got trained in this procedure under Prof Marie, and did this surgery recently on K P, a patient.. The patient is recovering well. KIMS Hospital, recently became the first centre in the country and one of the few centres in the world to do laryngeal reinnervation procedure for the vexing problem of bilateral vocal cord palsy. In this procedure, the nerve supply to the vocal cords is obtained from the nerves supplying the diaphragm and the nerve of the tongue. It is a long procedure requiring expertise in nerve resuturing with the ...

On either side of the laryngeal orifice in humans is a recess, termed the piriform sinus (also piriform recess, pyriform sinus, piriform fossa, or smugglers fossa), which is bounded medially by the aryepiglottic fold, laterally by the thyroid cartilage and thyrohyoid membrane. The fossae are involved in speech. The term piriform, which means pear-shaped, is also sometimes spelled pyriform (as in the diagram on this page.) Deep to the mucous membrane of the piriform fossa lie the recurrent laryngeal nerve as well as the internal laryngeal nerve, a branch of the superior laryngeal nerve. The internal laryngeal nerve supplies sensation to the area, and it may become damaged if the mucous membrane is inadvertently punctured. The piriform sinus is a subsite of the hypopharynx. This distinction is important for head and neck cancer staging and treatment. This sinus is a common place for food to become trapped; if foreign material becomes lodged in the piriform fossa of an infant, it may be ...

QUESTION:. I am a graduate student in my medical externship and Im trying my best to understand this:. Its my understanding that the internal branch of the recurrent laryngeal nerve mediates sensation below the vocal folds and mediates a cough reflex. This is why wed expect a cough if material is sensed below the level of the vocal folds in a pt with an intact cough response. If material gets below the vocal folds and no cough is produced, we call that silent aspiration.. Its my understanding that the superior branch of the laryngeal nerve mediates sensation above the vocal folds and an expected response to material above the level of the vocal folds is a swallow.. What about material sitting on top of the vocal folds (level 5 of the pen-asp scale)? Is that expected to elicit a cough or a swallow?. If material sitting on top of the vocal folds is considered penetration (because it did not go below the vocal folds) and is expected to elicit a cough, wouldnt that mean that there is such a ...

In the last decade the use of radioactive iodine (I131) has come to occupy a place beside subtotal thyroidectomy as a definitive treatment for hyperthyroidism. The excellent results-comparable in every way to those obtained with surgery-coupled with the ease of administration, make this form of therapy most attractive. Furthermore, the absence of the surgical complications of recurrent laryngeal nerve injury and parathyroid ablation, infrequent as they are, gives radioactive iodine a distinct advantage over operation. The one great obstacle to the more general use of this substance, especially in the age group under 40, has been concern regarding the possibility ...

Experiments were conducted in adult dogs to determine the respiratory activity of laryngeal muscles during wakefulness and sleep. We studied the EMG activity of three laryngeal muscles in five trained dogs, two of which were completely intact, and three of which had a previously-formed side-hole tracheal stoma. Pairs of electrodes were implanted chronically into the posterior cricoarytenoid muscle (PCA), a laryngeal dilator, cricothyroid (CT), and thyroarytenoid (TA), a laryngeal adductor. EMG electrodes were also inserted into the costal portion of the diaphragm. In wakefulness (W), slow wave sleep (SWS) and rapid eye movement (REM) sleep the EMGs of the PCA and CT muscles increased in intensity during diaphragm activation, with varying levels of basal activity during expiration. However, the greatest levels of inspiratory activity in PCA and CT during sleep were found in REM sleep, usually in the absence of augmented diaphragm EMG activity. This laryngeal muscle activity was associated with laryngeal

Deinnervation-reinnervation is a surgery used to treated spasmodic dypshonia. Spasmodic dypshonia is a disorder in which a patient has laryngeal spasms which cause spastic or strangled speech. While botox injections are most commmonly used for management of spasmodic dysphonia symptoms, de-innervation reinnervation has been shown to treat this disorder.The voice box, or larynx, is controlled by branches of the recurrent laryngeal nerve. This nerve branches to innervate, or power, specific muscles of the larynx.

To identify clinical and dosimetric factors associated with vagus nerve (VN) and recurrent laryngeal nerve (RecLN) injury following stereotactic ablative radiation therapy (SABR) in the chest.We examined the clinical courses and SABR plans of 67 patients treated for T1 or T2 non-small cell lung cancer of the upper right or left lung, including 2 who developed vocal cord paresis (VCP) following treatment. After developing a contouring atlas for the VN and RecLN in the thorax, dose to those structures was retrospectively determined for each patient, and we identified 12 patients whose treatment imparted significant dose to either nerve and who were assessable for more than 12 months follow-up. Biologically effective doses using linear-quadratic (LQ) and linear quadratic-linear (LQ-L) modeling were correlated with VN and RecLN toxicity.Of 12 patients, 2 developed VCP. The first underwent repeat SABR and received a cumulative single fraction equivalent dose (alpha/beta = 3; SFED3) of 37.4 or 64.5 Gy ...

Once positioned, a surgeon trained in ultrasonography used a 10MHz linear array ultrasound probe (Sonosite, USA) to localize the lesion. The adenoma was identified as a hypoechoic area close to the thyroid. The site was localized percutaneously and the neck marked over the maximum transverse and longitudinal planes. Where these two lines intersected a 3cm transverse mark was placed on the neck. Following skin preparation, the area of incision was infiltrated with 10cc of local anesthetic (xylocaine 0.5% with 1:10,000 adrenaline) and the incision made. Subplatysmal planes were created and the strap muscles were mobilized. The thyroid plane was then entered between the strap muscles and the sternocleidomastoid muscle. The plane was then continued down to the adenoma. Once visualized, the adenoma was not immediately mobilized, instead a 14-gauge needle was placed through the wound onto the adenoma. Once the lesion was concordant with ultrasound findings and the recurrent laryngeal nerve identified ...

From questions on page above. Non-caseating granulomas were identified on cytological and histological examination consistent with a diagnosis of sarcoidosis (figures 3 and 4). Sarcoidosis-associated vocal cord paralysis is uncommon. In general, vocal cord paralysis is usually bilateral or left-sided, probably due to decreased lymphatic drainage. In sarcoidosis, isolated right vocal cord paralysis has never been reported. Granulomatous invasion of the laryngeal nerves (perineuritis) and sarcoidosis-related cranial polyneuritis resulting in bilateral vocal cord paralysis have been reported rarely.1 Reports of unilateral left vocal cord paralysis are more common and are probably caused by compression by the bulky mediastinal disease on the left recurrent nerve at the level of the aorta. With a presumptive diagnosis of sarcoidosis based on the initial EBUS-TBNA cytology, oral steroids were administered for 2 months. The patient experienced no symptomatic improvement.. Studies suggest that the ...

Vocal cord paralysis occurs when the nerve impulses to your voice box (larynx) are disrupted. This results in paralysis of the vocal cord muscles.. Vocal cord paralysis can affect your ability to speak and even breathe. Thats because your vocal cords, sometimes called vocal folds, do more than just produce sound. They also protect your airway by preventing food, drink and even your saliva from entering your windpipe (trachea) and causing you to choke.. There are a number of causes of vocal cord paralysis including nerve damage during surgery, viral infections and certain cancers. Treatment for vocal cord paralysis usually involves surgery. Voice therapy can sometimes be an option.. Your vocal cords are two flexible bands of muscle tissue that sit at the entrance to the windpipe (trachea). When you speak, the bands come together and vibrate to make sound. The rest of the time, the vocal cords are relaxed in an open position, so you can breathe.. In most cases of vocal cord paralysis, only one ...

INTRODUCTION : The superior laryngeal nerve is the first branch of vagus nerve other than communicants. It originates at the level of C2 vertebra. It runs inferiorly and dorsally to internal carotid artery and internal jugular vein just above the bifurcation of common carotid it divides in to two terminal branches namely external branch of superior laryngeal nerve and internal branch of superior laryngeal nerve. Both supply the larynx to bring about the good quality of voice. AIMS AND OBJECTIVES : The aim of the study to emphasize the importance of external laryngeal nerve and its role invoice production and to give the surgical land marks for the successful thyroidectomy without affecting the voice. MATERIALS AND METHODS : Dissection method is used. Material used: 1. 50 mid sagittal section of head and neck from the embalmed cadaver, 2. Measuring Tape, 3. Vernier caliper, 4. Dissection set.

Disease Definition:. Lots of aspects of a persons life could be affected by vocal cord paralysis. Other than producing sounds, the vocal cords protect the airway be preventing food and drink from entering the windpipe also called trachea and causing the person to choke. This condition could be life-threatening in some rare cases. The person wont be able to breathe properly in case both of the cords are paralyzed in the closed position because it will reduce the flow of air into the lungs. On the other hand, the persons voice will be weak or hoarse in case the vocal cord is paralyzed in an open position. If the nerves that control the vocal cords are intentionally or accidentally damaged, such as after neck or throat surgery, vocal cord paralysis may occur. Vocal cord paralysis could also result from thyroid cancers or lung tumors ...

Laryngeal muscles normally demonstrate mild activity which is usually bilateral and symmetric. Active contraction of any skeletal muscle including the laryngeal muscle, particularly during the first half-hour following FDG injection, can result in increased activity. Therefore, efforts are made to isolate the patient from conversation during and after tracer injection. However, increased activity is not uncommonly seen within the laryngeal muscles likely due to their use prior to injection and during the short conversations with the technologist at the time of injection or immediately thereafter. Asymmetric activity can be seen with recurrent laryngeal nerve palsy and vocal cord paralysis, with greater activity on the unaffected side.. ...

True vocal cord paralysis signifies loss of active movement of the true vocal cord, or vocal fold, secondary to disruption of the motor innervation of the larynx. Disruption of innervation may occur along the length of the recurrent laryngeal nerves and the vagi and may include damage to the motor nuclei of the vagus. It should be differentiated from fixation of the vocal cord secondary to direct infiltration of the vocal fold, larynx, or laryngeal muscles. It should also be distinguished from fixation at the cricoarytenoid joint, encountered with rheumatoid arthritis or following traumatic intubation. ...

Thyroid and parathyroid surgery concerns around 50 000 patients a year in France. One of its main complications is paralysis of vocal cords. Indeed, the anatomy of the thyroid and its close location with the recurrent laryngeal nerve (responsible for the vocal cord movement) involves a possible lesion or inflammation of the nerve during the surgical procedure. This complication is common, affecting around 10% of thyroid or parathyroid patients following surgery. This complication can be reversible, with a speech therapy or a specific endoscopic treatment by an otolaryngologist.. Currently, a postoperative screening is performed by nasofibroscopy in the recovery room to directly visualize vocal cord mobility. This examination may be painful or badly tolerated by some patients.. Recent studies have highlighted the performance of ultrasound in this diagnosis. The protocol for these studies included an ultrasound distant of the intervention, while it is known that vocal cord paralysis may have ...

There are many different reasons for vocal cord paralysis. Some of the common causes are surgical injury to the recurrent laryngeal nerve (the nerve that provides movement for the vocal cord), cancers of the larynx (voice box) or the lungs, viruses, strokes, neck trauma, thyroid cancer, or traumatic placement of an endotracheal tube. Depending on the cause of the vocal cord paralysis, it may be temporary or permanent. In addition, there may only be a partial weakening of the vocal cord. In this instance, it is referred to as vocal cord paresis.. Vocal cord paralysis usually presents as hoarseness, a weak or breathy voice, or some coughing and choking while drinking thin liquids like water. Because the two vocal cords cannot adequately close during swallowing, patients are at risk of aspiration, where swallowed foods and/or liquids enter the trachea. This can lead to pneumonia. Patients with vocal cord paralysis will often complain of running out of air, especially during conversation.. It can ...

The functional organization of laryngeal motoneurons in the nucleus ambiguous (NA) was evaluated in adult male rats before and after recurrent laryngeal nerve section and reinnervation. Using retrograde double labeling techniques with fluorescent probes, we obtained the number and position of labeled neurons by using the Bioquant 3-D imaging system. Reinnervation was documented by electromyography. In nine control animals vector analysis revealed significant (p less than .05) separation of the posterior cricoarytenoid (PCA) muscle motoneurons and the thyroarytenoid and lateral cricoarytenoid (TA/LCA) muscle motoneurons. The PCA motoneurons were positioned ventromedially in the NA, and TA/LCA motoneurons were found dorsolaterally in the NA. Rostral-caudal separation was not significant. Electromyography revealed phasic electrical activity synchronous with respiration in the PCA, and activity synchronous with deglutition in the TA/LCA. In four animals surviving 15 weeks following recurrent laryngeal nerve

More than 4000 da Vinci Surgical Systems have been installed worldwide. Robotic surgery using the da Vinci Surgical System has been increasingly performed in the last decade, especially in urology and gynecology. The da Vinci Surgical System has not become standard in surgery of the upper gastrointestinal tract because of a lack of clear benefits in comparison with conventional minimally invasive surgery. We initiated robotic gastrectomy and esophagectomy for patients with upper gastrointestinal cancer in 2009, and we have demonstrated the potential advantages of the da Vinci Surgical System in reducing postoperative local complications after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy ...

This is the story of losing my voice for 7 months this year. Technically, I had what was diagnosed as vocal cord paralysis. I am writing this to help anybody else out there who is suffering from vocal cord paralysis. It can be healed naturally and without surgery!. At first, I figured my voice would come back in a few days, but it didnt. By no voice, what I mean is that I had a quiet, hoarse whisper, and I would lose my breath after trying to say more than a few sentences. A few days then turned into a month of no voice. I still trusted in my bodys innate ability to heal, but at the urging of my wife (we are now separated, a bit more on this later), I went to an urgent care facility after about a month. This was the first time Id gone to a medical practitioner in the conventional medical system in about 10 years. My confidence in urgent care facilities was low, and I was reminded why during my visit. With very few questions and no actual testing of anything in my body, the urgent care doctor ...

N2 - This systematic review of the literature addresses the medical management of spasmodic dysphonia (SD) and some related conditions. It was carried as part of the development of practice guidelines for the Academy of Neurologic Communication Disorders and Sciences (ANCDS). A search of electronic databases (PsychINFO, MEDLINE, and CINAHL) and hand searches of relevant edited books yielded 103 intervention studies in the categories of recurrent laryngeal nerve (RLN) section (20 references), the use of botulinum toxin (Botox) injections for the management of SD (58 references), and miscellaneous interventions (25 references). A review of this literature suggests that RLN section as a treatment for adductor SD results in a substantial degree of improvement for a substantial percentage of patients, but ...

Vocal cord paralysis, mostly affects only one vocal cord. If both of your vocal cords are affected, you may have difficulties with breathing and swallowing.

The thyroid (Greek thyreos, shield, plus eidos, form) consists of two lobes connected by an isthmus. It is located anterior to the trachea between the cricoid cartilage and the suprasternal notch. The normal thyroid is 12-20 g in size, highly vascular, and soft in consistency. Four parathyroid glands, which produce parathyroid hormone (Chap. 424), are located posterior to each pole of the thyroid. The recurrent laryngeal nerves traverse the lateral borders of the thyroid gland and must be identified during thyroid surgery to avoid injury and vocal cord paralysis. ...

Vagus Nerve. Vagus nerve, also called X cranial nerve or 10th cranial nerve, longest and most complex of the cranial nerves. The vagus nerve runs from the brain through the face and thorax to the abdomen. It is a mixed nerve that contains parasympathetic fibres. The vagus nerve has two sensory ganglia (masses of nerve tissue that transmit sensory impulses): the superior and the inferior ganglia. The branches of the superior ganglion innervate the skin in the concha of the ear. The inferior ganglion gives off two branches: the pharyngeal nerve and the superior laryngeal nerve. The recurrent laryngeal nerve branches from the vagus in the lower neck and upper thorax to innervate the muscles of the larynx (voice box). The vagus also gives off cardiac, esophageal, and pulmonary branches. In the abdomen the vagus innervates the greater part of the digestive tract and other abdominal viscera.. The vagus nerve has the most extensive distribution of the cranial nerves. Its pharyngeal and laryngeal ...

During thyroidectomy (surgery to remove the thyroid gland), the technique surgeons use to identify an important nerve appears to make a difference in terms of complications such as impairment of the parathyroid glands (which make a hormone that controls calcium levels), according to a report published Online First today by Archives of OtolaryngologyHead and Neck Surgery, one of the JAMA/Archives journals.. According to background information in the article, thyroidectomy is a common operation, but it can be associated with serious complications: paralysis of the recurrent laryngeal nerve (RLN, a nerve that transmits motor function and sensation to the larynx, or voice box) and hypoparathyroidism (caused by injury to the parathyroid glands). Unintentional damage to the RLN by this surgery is reported to cause nerve paralysis in one percent to two percent of cases. Extensive searching for the RLN during thyroid surgery may cause temporary or permanent hypoparathyroidism. The authors note two ...

the body. The Vagus Nerve is responsible for such varied tasks as heart rate, gastrointestinal peristalsis, sweating, and quite a few muscle movements in the mouth, including speech (via the recurrent laryngeal nerve) and keeping the larynx open for breathing. It also receives some sensation from the outer ear, via the Auricular branch (also known as Aldermans nerve) and part of the meninges.. The Vagus nerve is used to regulate the heartbeat and the muscle movement necessary to keep you breathing. It is the responsibility of the Vagus nerve to shift blood as needed. It maintains blood flow to the brain at all times to keep us from fainting. This nerve also regulates the chemical levels in the digestive system so that the intestines can process food and keep track of what types of nutrients are being gained from the food that is taken in. As late as the 1990s the medical field would clip the Vagus nerve at the Pyloric Sphincter when someone was having acute ulcer problems. They believed that ...

Operations on the parathyroid glands are very safe but sometimes there are complications.. Failure to cure: This is uncommon (3%), but is, in fact, the commonest complication! Reasons to fail are either because the surgeon has failed to realise that there is more than one tumour, or the tumour cannot be found.. The Voice: Intimately related to the thyroid gland and so sometimes the parathyroid glands are two nerves, one on each side of the neck. These recurrent laryngeal nerves provide the electricity for the movement of the vocal cords - which generate the voice. Injury to the nerve causes a weak and husky voice. Most injuries are a temporary bruising, with full recovery. However a permanent injury will result in a permanently weak voice. The risk of a permanent injury in parathyroid surgery is less than 1% (one in one hundred).. The Scar: Parathyroid surgery is undertaken through a 3 - 4cm scar that follows the natural creases in the neck. Usually it heals well leaving only a thin line. The ...

Cervical lymph nodes are located in the sides and back of the neck. Note the thickening of the left platysma muscle (arrow). Figure 23b. The adult cases that do occur usually are due to foreign body perforation (26). Retropharyngeal edema due to calcific tendinitis of the longus colli in a 71-year-old woman. The lymph nodes beneath and surrounding the thyroid gland, breathing tube (trachea) and swallowing tube (esophagus) that run in between the carotid arteries and extend in the area beneath the breast bones are called the central compartment lymph nodes. Groups of lymph nodes are found in the neck, around the collarbone, in the armpit (axilla), and in the groin. With this disease, autoantibodies stimulate the thyroid-stimulating hormone receptors on follicular cells, in effect mimicking thyroid-stimulating hormone. The vocal cords should be evaluated for signs of asymmetry, as paralysis may occur owing to compression of the recurrent laryngeal nerve (40). Note the tapered superior and inferior ...

It was not until the 19th century that Billroth, Kocher, Halsted, and others refined the thyroidectomy operation into a standard treatment for thyroid cancer with advancements in anti-septic technique, anesthesia, recurrent laryngeal nerve protection, and parathyroid preservation.1,2 In the first half of the 20th century, oncologic resection for papillary thyroid cancer (PTC) commonly incorporated a block dissection, which sacrificed the sternocleidomastoid muscle, spinal accessory nerve, and marginal mandibular branch of the facial nerve resulting in significant deformity. George Crile Jr. heralded a more limited dissection with successful oncologic outcomes, which sparked the on-going debates regarding extent of dissection, implications of neck metastases, and prognostic factors for risk stratification.3 As early detection of PTC increased by the 1980s with the widespread use of diagnostic ultrasound and fine needle aspiration biopsy, controversy regarding the management of smaller tumors ...

The deep part of the cardiac plexus is situated in front of the bifurcation of the trachea (known as the carina), above the point of division of the pulmonary artery, and behind the aortic arch. It is formed by the cardiac nerves derived from the cervical ganglia of the sympathetic trunk, and the cardiac branches of the vagus and recurrent laryngeal nerves. The only cardiac nerves which do not enter into the formation of the deep part of the cardiac plexus are the superior cardiac nerve of the left sympathetic trunk, and the lower of the two superior cervical cardiac branches from the left vagus nerve, which pass to the superficial part of the plexus. ...

Chemotherapy or radiation therapy may be used in the case of advanced stages of cancer or distant metastases. In most cases, the first sign of cancer of the thyroid is the thyroid gland in the neck. However, many adults is a small unit in the thyroid, but less than 5%, is detected in the malignant typical of these units. Sometimes, the first sign is a lymph node that is enlarged. Then, that the symptoms are present, the pain, in front of the voice change and neck because of the involvement of the recurrent laryngeal nerve.

METHODS AND PROCEDURES: We have performed thoracoscopic esophagectomy while the patient was in a prone position for 44 patients with esophageal cancer between September 2009 and September 2011. The indications for this operation were the absence of severe pleural adhesion, cases with T1b to T3 cancer, and cases without preoperative chemoradiotherapy. Patients were placed in a prone position, and five trocars were inserted into the right thoracic cavity; only the left lung was ventilated, and pneumothorax was maintained with 6 mmHg of CO2 gas. The anterior pleura of the upper posterior mediastinum was incised between the esophagus and the trachea. The lymph nodes around the right recurrent laryngeal nerve and the upper esophagus were dissected. The esophagus was mobilized from the trachea in the first step and from the posterior structure in the second step. The middle and lower esophagus was also mobilized in the same manner as that for the upper esophagus; the lymph nodes around the esophagus ...

Kutsche and Van Mierop4 described CORSA in 1984. They found this anomaly in 4 of 21 infants (19%) studied for aortic arch interruption. The origin of the vessel was seen along with the origins of the internal and external carotid arteries as a trifurcation, at the level of the thyroid gland. It then descended down the neck to enter the right arm. The right recurrent laryngeal nerve was seen to course around the origin of the right subclavian artery, much higher than normal. The pathogenesis of CORSA can be explained by impairment of fourth aortic arch development, before the involution of the right ductus caroticus (segment of the dorsal aorta between the third and fourth arches). The right ductus caroticus, which normally involutes at the 14-mm crown-rump length, is retained and forms the initial segment of the right subclavian artery at its origin from the common carotid bifurcation. The seventh intersegmental artery and the dorsal aorta below the level of the third arch form the rest of the ...

With 2 channels, powerful audio, an easy to understand display, and a built-in stimulator, the Neurosign 100 intra-operative nerve monitor is an excellent choice when a simple monitor is required for facial and laryngeal nerve monitoring. Neurosign 100 enables ENT surgeons to monitor the facial nerve during mastoidectomy and is used by general surgeons to monitor the recurrent and superior laryngeal nerves during procedures involving the thyroid gland.. Neurosign 100 is also suitable to monitor the accessory, hypoglossal or trigeminal nerves individually.. ...

The aim of this study was to evaluate the diagnostic accuracy of intraoperative neuromonitoring (IONM) in predicting postoperative nerve function during thyroid surgery and its consequent ability to assist the surgeon in intraoperative decision making.

Thyroid surgery is generally performed under a general anaesthetic although it can be done under local anaesthesia in special circumstances if required. An incision is made in the front of the neck, 2 to 3 cm above the collarbone. The underlying muscles are opened or divided to expose the thyroid gland which the surgeon then removes either totally or in part. Great care is taken not to injure the nerves which control the voice box (laryngeal nerves) and every attempt is made to preserve the parathyroid glands which control the bodys calcium levels. Sometimes the parathyroid glands may be autotransplanted into a nearby muscle to preserve their function. The muscles are then put together again and the skin incision is closed with sutures that will either absorb or be removed soon after your operation.. ...

What is to explain? If a longer tongue makes it easier for them get food from deeper in the tree, which seems highly likely, natural selection will tend to lead to them having longer tongues.. Its not as if increasing the length of the tongue requires some fancy mutation, unless you have reports to the contrary.. It seems perfectly in accord with evolutionary theory.. If you want a real puzzle, how would you explain the arrangement of the laryngeal nerve of the giraffe in the context of an intelligent creator?. http://scienceblogs.com/grrlscientist/2010/06/the_laryngeal_nerve_of_the_gir.php. It is easy to explain by evolution, because evolution is limited to small steps at each generation. There is no such problem with the elongation of the woodpeckers tongue - it can just get a tiny bit longer, on average, at each generation... But it makes no sense for an omnipotent creator to have left the arrangement of the nerve as it is.. Everything makes so much more sense without your ...
