OBJECTIVE: Recognition of extralaryngeal branching of the recurrent laryngeal nerve is crucial because prevention of vocal cord paralysis requires preservation of all branches of the recurrent laryngeal nerve. We assessed the prevalence of extralaryngeal branching of the recurrent laryngeal nerve and the median branching distance from the point of bifurcation to the entry point of the nerve into the larynx. MATERIAL AND METHODS: Prospective operative data on recurrent laryngeal nerve branching were collected from 94 patients who underwent thyroid or parathyroid surgery between September 2011 and May 2012...

INTRODUCTION: Thyroid and parathyroid surgery (TPTS) is associated with risk of injury to the recurrent laryngeal nerve, superior laryngeal nerve and voice changes. Intraoperative neuromonitoring (IONM), intermittent or continuous, evaluates the functional state of the laryngeal nerves and is being increasingly used. This means that points of consensus on the most controversial aspects are necessary. OBJECTIVE: To develop a support document for guidance on the use of IONM in TPTS...

OBJECTIVE: Laryngeal electromyography (LEMG) of the thyroarytenoid (TA) muscle alone may not be sufficient in all patients to characterize or prove a recurrent laryngeal nerve (RLN) lesion in cases of vocal fold immobility. LEMG of the posterior cricoarytenoid (PCA) muscle may provide additional information. STUDY DESIGN: Retrospective review. METHOD: Between 2008 and 2016, 339 patients in our laryngeal paralysis clinic were examined by transcutaneous needle TA-LEMG and, if tolerated, by PCA-LEMG...

Radiation induced gastroparesis as well as the other autonomic nervous system radiation induced neuropathies are poorly described in the literature. A case of gastroparesis associated with phrenic and recurrent laryngeal nerves paralysis was observed in a 69-year old patient. She was already treated two times by rachis radiotherapy in a context of breast cancer with bone metastases. Anatomical and chronological correlation of lesions, concomitant nerve damage in the radiation fields and elimination of the main differential diagnoses allowed us to link this case of gastroparesis with the background of radiotherapy...

An 18-month-old male entire Bloodhound dog was presented with a six-week history of progressive inspiratory dyspnoea, stridor, dysphonia and exercise intolerance. CT scan performed elsewhere had revealed the presence of an unencapsulated nodular mass (3x1x5 cm) dorsal to the larynx and first tracheal rings. Laryngoscopy demonstrated the presence of bilateral laryngeal paralysis and distorted laryngeal architecture suggestive of extraluminal compression. Histopathology results of incisional biopsies from the mass were suggestive of a benign non-neoplastic muscular lesion...

OBJECTIVE: There is an unmet need for tissue-engineered three-dimensional (3D) muscle constructs for laryngeal reconstruction. Functional engineered muscle could be used to repair postoncologic or traumatic defects or to medialize the vocal fold in cases of paresis/paralysis. Autologous, organized, engineered muscle that has adequate bulk integrates into host tissue and restores function currently does not exist. METHODS: Primary skeletal muscle progenitor cells (MPCs) were isolated from F344 rats...

In this article, we present a case of recurrent laryngeal nerve palsy not caused by nerve injury but due to local anesthetic infiltration that was applied prior to central venous catheterization. A 47-year-old female patient was admitted to emergency room with fatigue and nausea and was diagnosed with acute renal failure. Right jugular venous catheterization was performed for emergency hemodialysis with Seldinger technique using middle approach. Within minutes and immediately after the procedure the patient complained of hoarseness and shortness of breath, and she had stridor in her physical exam...

In the 1890s, one of Charcot's most important protégés, Dr. Paul Richer (1849-1933), drew and sculpted a series of representations of the main types of nerve pathology. That series included drawings of pleomorphic hysterical crises and sculptures depicting patients suffering from labio-glosso-laryngeal paralysis and myopathy, as well as Parkinson's disease. Richer was a resident at La Salpêtrière and, in 1882, became head of the Charcot museum. Early in his career, despite having no formal artistic training, he could represent masterfully, in drawings and sculptures, people's tragic suffering from neurological diseases...

INTRODUCTION: Glottic leakage during phonation is a direct consequence of unilateral vocal fold (VF) paralysis. This air leakage can be in the horizontal plane and in the vertical plane. Presently, there is no easily applicable medical device allowing noninvasive, office-based measurement of the relative vertical position of the VFs. The larynx ruler (LR) is a laser-based measuring device that could meet the previously stated need, using a flexible endoscope. This study represents a proof of concept regarding the use of the LR in assessing VF relative positions in the vertical plane...

REVIEW
Yike Li, Gaelyn Garrett, David Zealear
Vocal fold paralysis (VFP) refers to neurological causes of reduced or absent movement of one or both vocal folds. Bilateral VFP (BVFP) is characterized by inspiratory dyspnea due to narrowing of the airway at the glottic level with both vocal folds assuming a paramedian position. The primary objective of intervention for BVFP is to relieve patients' dyspnea. Common clinical options for management include tracheostomy, arytenoidectomy and cordotomy. Other options that have been used with varying success include reinnervation techniques and botulinum toxin (Botox) injections into the vocal fold adductors...
