Branches of the VAGUS NERVE. The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibers to the cricothyroid muscles, and internal branches, which carry sensory fibers. The RECURRENT LARYNGEAL NERVE originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.

Atrophy of the posterior cricoarytenoid muscle as an indicator of recurrent laryngeal nerve palsy. (1/68)

BACKGROUND AND PURPOSE: The posterior cricoarytenoid (PCA) muscle is one of the intrinsic muscles of the larynx innervated by the recurrent laryngeal nerve. As such, recurrent laryngeal nerve palsy should not only result in paralysis of the true vocal cord or thyroarytenoid muscle but also in a similar change in the PCA muscle. The ability of CT and MR imaging to depict denervation atrophy in the PCA muscle in patients with recurrent laryngeal nerve palsy was evaluated. METHODS: Two investigators reviewed the CT and/or MR studies of 20 patients with a clinical history of vocal cord paralysis. The appearance of the PCA muscle was given a rating of 0, 1, 2, 3, or 4, with 0 being definitely normal and 4 being definitely abnormal or atrophic. Each study was also reviewed for the presence or absence of other features of vocal cord paralysis: thyroarytenoid muscle atrophy, anteromedial deviation of the arytenoid cartilage, an enlarged piriform sinus and laryngeal ventricle, and a paramedian cord. RESULTS: Atrophy of the PCA muscle was shown unequivocally in 65% of the cases and was most likely present in an additional 20%. The frequency with which other features of vocal cord paralysis were seen was as follows: thyroarytenoid atrophy, 95%; anteromedial deviation of the arytenoid cartilage, 70%; enlarged piriform sinus, 100%; enlarged laryngeal ventricle, 90%; and a paramedian cord, 100%. CONCLUSION: Atrophy of the PCA muscle may be commonly documented on CT and MR studies in patients with recurrent laryngeal nerve palsy and vocal cord paralysis, and therefore should be part of the constellation of imaging features of vocal cord paralysis. This finding is particularly useful when other imaging findings of vocal cord paralysis are absent or equivocal.  (+info)

Quantitative analysis of the anatomy of the epineurium of the canine recurrent laryngeal nerve. (2/68)

The purpose of this investigation was to determine the amount of epineurium surrounding the recurrent laryngeal nerve (RLN) compared with a limb nerve, that to flexor hallicus longus (NFHL). Nerve samples were obtained from 10 adult dogs and studied using scanning electron microscopy and light microscopy to measure the relative proportion of epineurium and the relative proportions of adipose and collagenous tissue comprising the epineurium in both nerves. Significantly greater relative epineurial cross-sectional areas and adipose content were found in the RLN than in the NFHL. Based on observations on noncranial peripheral nerves, the findings indicate that the RLN is better protected against deformational forces associated with compression than stretching forces. The RLN may not be structured well for successful reinnervation after injury. The patterns observed for adipose tissue in RLN epineurial tissue appeared unique compared with those previously reported in peripheral nerves. The primary role associated with adipose tissue is to 'package' the nerve for protection. The RLN is considered to be a vital nerve in the body, as are other cranial nerves. The large proportions of adipose tissue in the epineurium may relate to the importance of protecting this nerve from injury.  (+info)

Synchronized fast rhythms in inspiratory and expiratory nerve discharges during fictive vocalization. (3/68)

In precollicular decerebrate and paralyzed cats, respiratory nerve activities were recorded during fictive vocalization (FV), which consisted of a distinctive pattern of 1) decreased inspiratory (I) and expiratory (E) phase durations, 2) marked increase of phrenic activity and moderate changes of recurrent laryngeal (RL) and superior laryngeal (SL) I activities, and 3) massive recruitment of laryngeal and abdominal (ABD; lumbar) E activities. FV was produced by electrical stimulation (100 Hz) in the midbrain periaqueductal gray (PAG) or its putative descending pathways in the ventrolateral pons (VLP). Spectral and correlation analyses revealed three types of effect on fast rhythms during FV. 1) I activities: the coherent high-frequency oscillations in I (I-HFO, 60-90 Hz) present in phrenic and RL discharges during the control state did not change qualitatively, but there was an increase of power and a moderate increase (4-10 Hz) of frequency. Sometimes a distinct relatively weak stimulus-locked rhythm appeared. 2) RL and SL activities during E: in recruited discharges, a prominent intrinsic rhythm (coherent E-HFOs at 50-70 Hz) appeared; sometimes a distinct relatively strong stimulus-locked rhythm appeared. 3) ABD activities during E: this recruited activity had no intrinsic rhythm but had an evoked oscillation locked to the stimulus frequency. Thus FV is characterized by 1) appearance of prominent coherent intrinsic rhythms in RL and SL E discharges, which presumably arise as a result of excitation and increased interactions in laryngeal networks; 2) modification of intrinsic rhythmic interactions in inspiratory networks; and 3) evoked rhythms in augmenting-E neuron networks without occurrence of intrinsic rhythms.  (+info)

Nonrecurrent laryngeal nerve during carotid artery surgery: case report and literature review. (4/68)

The anomalous position of a nonrecurrent inferior laryngeal nerve predisposes it to injury during surgery in the neck. We present the case of a patient who underwent a carotid endarterectomy in which a rare left nonrecurrent laryngeal nerve was found intraoperatively. This abnormality, which occurs much less often on the left than the right side of the neck, should be familiar to vascular surgeons. Historical, embryologic, and surgical significance of this anomaly is addressed.  (+info)

Left vocal cord paralysis associated with long-standing patent ductus arteriosus. (5/68)

SUMMARY: Left vocal cord paralysis in association with patent ductus arteriosus is unusual. We report a patient with long-standing patent ductus arteriosus (PDA) in whom CT studies obtained before and after paralysis developed showed an interval increase in size of the pulmonary trunk. The pathogenesis of left vocal cord paralysis in association with long-standing PDA is discussed.  (+info)

Relationship between the recurrent laryngeal nerve and the inferior thyroid artery: a study in corpses. (6/68)

The anatomical relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) was studied in 76 embalmed corpses, 8 females and 68 males. In both sexes, the RLN lay more frequently between branches of the ITA.; it was found in this position in 47.3% of male corpses and 42.8% of female ones. On the right, RLN was found between branches of the ITA in 49.3% of the cases, anterior to it in 38.04%, and posterior in 11.26%. On the left, the RLN lay between branches of the ITA in 44.45%, posterior to the ITA in 37.05%, and anterior to it in 18.05% of the cases. In 62.68% of the cases, the relationship found on one side did not occur again on the opposite side. There was a significant difference (p<0.05) in the distribution of the 3 types of relationships between the RLN and the ITA, on the right and on the left. Racial variations could contribute to an explanation of the differences observed by authors of different countries in the relationship between the RLN and the ITA.  (+info)

Use of the laryngeal mask airway in thyroid and parathyroid surgery as an aid to the identification and preservation of the recurrent laryngeal nerves. (7/68)

A prospective study was carried out in patients undergoing thyroid and parathyroid surgery using a laryngeal mask airway (LMA) and electrical nerve stimulation to identify the recurrent laryngeal nerves. A total of 150 consecutive patients undergoing thyroid and parathyroid surgery by a single surgeon were assessed for suitability of anaesthesia via the LMA. Peroperatively, a fibre-optic laryngoscope was passed through the LMA to enable the anaesthetist to visualise the vocal cords while adduction of the cords was elicited by applying a nerve stimulator in the operative field. In all, 144 patients were selected for anaesthesia via the LMA. Fibre-optic laryngoscopy and nerve stimulation were performed in 64 patients (42.7%). The trachea was deviated in 51 (34.0%) and narrowed in 33 (22.0%). The recurrent laryngeal nerves were identified in all patients. There were no cases of vocal cord dysfunction resulting from surgery. The LMA can be safely used for thyroid and parathyroid surgery even in the presence of a deviated or narrowed trachea. It can assist in identification and preservation of the recurrent laryngeal nerve and is, therefore, of benefit to both patient and surgeon.  (+info)

Selective suppression of late laryngeal adductor responses by N-methyl-D-aspartate receptor blockade in the cat. (8/68)

Laryngeal adductor responses to afferent stimulation play a key role in airway protection. Although vital for protection during cough and swallow, these responses also must be centrally controlled to prevent airway obstruction by laryngospasm during prolonged stimulation. Our purpose was to determine the role of N-methyl-D-aspartate (NMDA) receptors in modulating early R1 responses (at 9 ms) and/or later more prolonged R2 responses (at 36 ms) during electrical stimulation of the laryngeal afferent fibers contained in the internal branch of the superior laryngeal nerve in the cat. The percent occurrence, amplitude, and conditioning of muscle responses to single superior laryngeal nerve (SLN) stimuli presented in pairs at interstimulus intervals of 250 ms were measured in three experiments: 1) animals that had ketamine as anesthetic premedication were compared with those who did not, when both were maintained under alpha-chloralose anesthesia. 2) The effects of administering ketamine in one group of animals were compared with increasing the depth of alpha-chloralose anesthesia without NMDA receptor blockade in another group of animals. 3) The effects of dextromethorphan (without anesthetic effects) were examined in another group of animals. In the first experiment, the occurrence of R2 responses were reduced from 95% in animals without ketamine premedication to 25% in animals with ketamine premedication (P = 0.015). No differences occurred in the occurrence, amplitude, latency, or conditioning effects on R1 responses between these groups. In the second experiment, the occurrence of R2 responses was reduced from 96 to 79% after an increase in the depth of anesthesia with alpha-chloralose in contrast with reductions in R2 occurrence from 98 to 19% following the administration of ketamine to induce NMDA receptor blockade along with increased anesthesia (P = 0.025). In the third experiment, R2 occurrence was reduced from 89 to 27% (P = 0.017) with administration of dextromethorphan while R1 response occurrence and amplitude did not change. In each of these experiments, NMDA receptor blockade did not have significant effects on cardiac or respiratory rates in any of the animals. The results demonstrate that NMDA receptors play an essential role in long latency R2 laryngeal responses to laryngeal afferent stimulation. On the other hand, early R1 laryngeal adductor responses are likely to involve non-NMDA receptor activation.  (+info)

In patients presenting with persistent hoarseness due to left recurrent laryngeal nerve (LRLN) palsy and an abnormal left hilum on chest radiographs, a major cause is bronchogenic carcinoma.

OBJECTIVE To demonstrate that a recombinant adeno-associated viral vector (rAAV) carrying the gene for green fluorescent protein (GFP) could be delivered to the rat brainstem by remote injection into the recurrent laryngeal nerve. STUDY DESIGN/METHODS rAAV-GFP is a serotype 2 adeno-associated vector containing the cDNA of GFP and woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) under the control of the CAG promoter (obtained from Matthew During, PhD, Thomas Jefferson Medical College). Five microliters or 10 microL of 1.4 x 109 particles/microL of rAAV-GFP were injected into the right recurrent laryngeal nerve of adult Sprague-Dawley rats. Rats were killed and perfused at 3 (n = 3) and 11 weeks (n = 3). Brainstems were removed and cryosectioned. Fluorescent in-situ hybridization (FISH) was performed on cryosections from animals killed at 3 weeks using a cDNA probe for woodchuck polyribosomal enzyme within the rAAV vector. In a third group (n = 2), Fluoro-Gold (Fluorochrome, Inc.,
Apart from hypoparathyroidism, dysfunction of the recurrent laryngeal nerve (RLN) is the most common complication following thyroid surgery. In consequence, the voice impairment leading to communication work-related problems and affecting psychological and social aspects of the individuals functioning diminishes the overall quality of life, being the common reason for medicolegal claims and litigation. The reported RLN palsy rate varies in the literature from 0% (for first-time thyroid surgery performed by an experienced endocrine surgeon) to as much as 20% (for reoperative thyroid surgery or thyroid malignancy surgery performed in low-volume centers), depending mostly on the type of thyroid disease (benign vs. malignant goiter), type (first-time vs. reoperation) and the extent of thyroid resection (subtotal vs. total thyroidectomy), surgical technique (with or without routine RLN identification) and the surgeons experience (low-volume vs. high-volume thyroid surgery center.. In 1938, Lahey ...
The incidence of paralysis in our series was much less than that reported by Jung et al. 16 (3% vs. 20.8%). In Jungs series, all exposures were right sided. By contrast, surgeons in our practice performed, almost exclusively, either right- or left-sided approaches, depending on their training and personal preference. The paralysis rate for our right-sided procedures compares closely with the overall paralysis rate reported by Jung et al. This apparent predilection for vocal fold paralysis after a right-sided approach has previously been documented.1,4 Surgeons, the majority of whom were right hand dominant, found the right-sided approach technically easier and so operated from that side more frequently.1,15,17 The preponderance of right-sided events was presumed to be a function of the frequent use of that approach. But there are also anatomical differences between the RLN on the right and left18 that may result in a greater propensity of right-sided injury. The right RLN is shorter and travels ...

The arteria lusoria is a rare anomaly of the right subclavian artery. This artery arises from the aortic arch distal to the left subclavian artery crossing the midline behind the oesophagus. This abnormality remains generally silent, is often an incidental X-ray finding and is often associated with a non-recurrent laryngeal nerve. The embryological nature of such anatomical variations originally results from the vascular disorder known as arteria lusoria in which the fourth right aortic arch is abnormally absorbed, and is therefore unable to drag the right recurrent laryngeal nerve down when the heart descends and the neck elongates during embryonic development. The surgeon must be aware of the possibility of a non-recurrent laryngeal nerve, which directly arises from the cervical vagus and therefore represents a severe potential pitfall during thyroidectomy. When the preoperative studies (e.g. CT) show the presence of a lusorian artery, the surgeon will be aware of this association. As for as ...

Galen demonstrating the effects of the recurrent laryngeal nerve during the dissection of a pig. The recurrent laryngeal nerves are branches of the vagus nerves that control nearly all of the intrinsic muscles of the voice box. Therefore, injury to one or both may cause hoarseness or even a complete inability to phonate. The etymology is nothing to write home about, but the story of their discovery definitely is. The famed Greek physician Galen, while conducting an experiment on a live, strapped-down pig, accidentally cut both laryngeal nerves; the pig continued to struggle but completely stopped squealing. He ultimately traced out the path of the nerves and confirmed that they originated from the vagus nerves. He noted that there is a hairlike pair [of nerves] in the muscles of the larynx on both left and right, which if ligated or cut render the animal speechless without damaging either its life or functional activity. Galen held a public demonstration of his experiment in Rome that was ...
We described the characteristics of the hospitals and surgeons using absolute frequencies with percentages for categorical variables. We calculated mean values with standard deviations and median values with minimum-maximum intervals for continuous variables. We calculated 95% confidence intervals of complication rates using an exact method based on binomial distribution and used the Spearmans rank correlation test to investigate correlation between surgeons length of experience and age, as well as the overall number of thyroidectomies previously undertaken. To identify variables associated with recurrent laryngeal nerve palsy and hypoparathyroidism, we compared thyroid procedures with and without complications. We used χ2 and Mann-Whitney tests to compare categorical and continuous variables, respectively. We identified the factors associated with the probability of each complication by calculating crude and adjusted odds ratios using a mixed effects logistic regression. This approach was ...
Editor - In their lesson of the week article, Raja Shariff et al listed a differential diagnosis of Ortners syndrome which should have included not just compression of the left recurrent laryngeal nerve (LRLN) by left atrial enlargement but also compression of the recurrent laryngeal nerve by a large thrombotic formation that completely occlude(s) the outflow tract of the pulmonary artery, as in the case of pulmonary embolism (PE) reported by Polverino et al.1,2 Accordingly, for the sake of completeness, they should have evaluated their patient not only for left atrial enlargement but also for stigmata of PE.. The rationale for evaluation for PE even when left atrial enlargement has been documented by echocardiography is that mitral stenosis is a risk factor for PE (and, hence, for Ortners syndrome) in its own right, and also a risk factor for mitral stenosis-related mortality.3-5 The occurrence of mitral stenosis-related PE was exemplified by a 43-year-old man who presented with severe ...

Purpose: Traction is the most common cause of injury to the recurrent laryngeal nerve (RLN) in endocrine neck surgery. The purpose of this study was to evaluate specific alterations to the electromyogram (EMG) and verify safe alarm limits in a porcine model of sustained traction of the RLN using continuous intraoperative neuromonitoring (C-IONM). Methods: Sixteen Norwegian Landrace pigs were anesthetized and intubated with a tracheal tube with a stick-on laryngeal electrode. EMG was recorded at baseline (BL) and during sustained traction applied to each RLN until 70 % amplitude decrease from BL, and during 30-min recovery. Results: In 29 nerves at risk (NAR), BL amplitude and latency values were 1098 ± 418 (586-2255) μV (mean ± SD (range)) (right vagus) and 845 ± 289 (522-1634) μV (left vagus), and 4.7 ± 0.5 (4.1-5.9) ms and 7.9 ± 0.8 (6.7-9.6) ms, respectively. At 50 % amplitude decrease, latency increased by 14.0 ± 5.7 % (right side) and 14.5 ± 9.1 % (left side) compared with BL. ...

You also have to consider that even if there is a way to alter our eyes without making them more fragile, there may be no way to get from our current eye to the new one without going through steps in between that reduce our fitness. A good example is the recurrent laryngeal nerve (RLN), the nerve that controls your larynx. You would expect that the nerve would split off from the main vagus nerve around the level of the larynx and run directly to it. But this isnt the case. The two branches of the RLN run all the way down into your chest before splitting off and running back up to your larynx. The left RLN in particular takes a very indirect approach, looping under your aortic arch before running all the way up to your larynx ...
A patient claimed that her consultant ENT surgeon negligently injured her recurrent laryngeal nerve (RLN) during a thyroidectomy, leading to an RLN palsy.
An example is hoarseness after thyroid surgery caused by temporary or permanent damage to a recurrent laryngeal nerve. g. dislocation of a joint replacement or the breakdown of an anastomosis. External intestinal fistula The development of an external intestinal fistula is a serious complication of an abdominal bowel resection. If an anastomosis breaks down because of poor technique, ischaemia or failure to heal, leaking bowel content may cause generalized peritonitis. When the anastomosis has been walled off with omentum the leakage will be confined until it finds its way out through the wound or, if a drain has been placed, through the drain site. Insulin-dependent diabetics should not be on long-acting preparations. The complication to be avoided at all costs is hypoglycaemia and its associated unconsciousness, which may be fatal. This is prevented by giving intravenous glucose, and erring on the side of a high rather than a low blood sugar. g. converts hernia repair into an abdominal ...
INTRODUCTION: In thyroid and parathyroid surgery iatrogenic injury of the parathyroid glands or the recurrent laryngeal nerve (RLN) is a possible complication that needs to be prevented. The visible contrast between thyroid and parathyroid tissue is delicate to observe. The aim of this pilot study was to collect in vivo spectral reflectance-signatures of critical tissue types encountered during thyroid and parathyroid surgery, and to assess the presence of useful spectral distinctive features that might be applied for future devices enabling intraoperative tissue-specific image contrast enhancement. METHODS: Wide-band spectra (350-1830nm, 1nm resolution) were collected in vivo during thyroid and parathyroid surgery. Subjected to tissue type accessibility, on average 2 tissue types per patient were measured. For each tissue type, 5 spectra were recorded per site, covering 1-2 sites per tissue type. Mean tissue spectra were calculated for all measured tissue types. After visually comparing these ...
All of the named peripheral nerves can be identified by the end of the eighth week. As viscera and muscle masses shift in their position, their nerves accommodate the shifts by increasing in length. The heart and diaphragm receive most of their innervation when they are in the cervical region. Since their nerves (superior, middle and inferior cervical cardiac nerves of the heart and phrenic nerve of the diaphragm) follow them as they migrate caudally, they begin in the neck and descend through the root of the neck and thorax. Likewise, the larynx receives its motor innervation from the vagus when the aortic arches are farther cranially. When the arches migrate caudally with the heart, the recurrent laryngeal nerve follows causing it to recur in its course to the larynx. In the adult it passes around the aortic arch and ligamentum arteriosum on the left, which were derived from the fourth and sixth arches, respectively. Since on the right side the distal part of the sixth arch disappears, the ...

Dr. Ladenson (Dans endocrinologist) just stopped by to give us a bit more info. He spoke to Dans surgeon who was optimistic about being close to completing the surgery. The surgeon found several nodes, but many of them were very difficult to access. He had nodes posterior to both clavicles and one on the left that was adjacent to the subclavian artery. It also turns out that the nodes identified by ultrasound in the central compartment was actually residual thyroid tissue. This part of the surgery was especially difficult because of close proximity to the recurrent laryngeal nerve and phrenic nerve. Dr. Ladenson and Dr. Tufano (the ENT surgeon) both sound optimistic about his recovery time. We are relieved ...
Benefits: General anesthesia provides an optimal surgical field with a secured airway. This is particularly crucial given the surgical risk to vital structures in the anterior neck (carotid artery, internal jugular vein, recurrent laryngeal nerve, trachea, and esophagus).. Drawbacks: The side effects of general anesthetics are the only drawbacks of this technique, but this is the only manageable option.. Preoperative airway concerns: Due to the nature of the disease process, a careful airway exam including neck range of motion and its impact on neurologic symptoms should be obtained prior to induction. In general, the airway should be secured with the technique that is most familiar to the anesthetic team and least likely to cause airway trauma or worsen neurologic symptoms with extremes of positioning. This may be an awake fiberoptic intubation in a patient with a suspected difficult airway and severe gastroesophageal reflux disease or the use of video laryngoscopy or traditional direct ...
The most important concern in all head and neck cancer patients is the condition of the airway. A history of dyspnea, dysphagia, obstructive sleep apnea, a change in the voice, exercise intolerance, radiation to the head and neck region, previous head and neck surgery, and previous difficulty with intubation may be clues to a difficult airway.. Some patients with pharyngeal, neck, or anterior mediastinal tumors may have airway obstruction when lying supine but can breathe when lying prone or in a lateral position. Apart from a thorough physical examination of the airway from the teeth inwards, preoperative evaluation of the airway may include direct and indirect laryngoscopy, bronchoscopy, and radiological tests, such as antero-posterior and lateral X-rays films of the neck, CT scans, and MRI images to determine the state of the airway anatomy and the extent of cancer spread.. The condition of the recurrent laryngeal nerve should be known preoperatively for medical and medico-legal reasons ...

Results: The mean initial labelling index for p53 in nonrecurrent tumours was 0.38% (0-1.58%), while it was 0.46% (0-3.65%) for recurrent adenomas. The mean initial MIB-1 index for nonrecurrent tumours was 1.63% (0.08-9.36%), while for recurrent tumours it was 1.92% (0-7.76%). The percentage of p53 positive adenomas was 66% for nonrecurrent tumours and 68% for recurrent tumours. None of the differences in the labelling indices between the recurrent and nonrecurrent groups was statistically significant. As 12 patients (38%) in the nonrecurrent group had undergone radiotherapy as initial adjuvant therapy after surgery and none of the recurrent group had done so, patients who did not receive radiotherapy in the nonrecurrent group were analyzed separately. Again, none of the differences in the labelling indices between the recurrent and nonrecurrent groups was statistically significant when the effect of radiotherapy was removed from the analysis.. ...

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. ...

TY - JOUR. T1 - CURRENT STATUS AND FUTURE PERSPECTIVES OF ROBOTIC SURGERY. AU - Suda, Koichi. AU - Uyama, Ichiro. PY - 2016/9/1. Y1 - 2016/9/1. 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 ...
