OBJECTIVE To determine the differences in myelination between the human recurrent laryngeal nerve and superior laryngeal nerve. METHODS Fifteen confirmed laryngeal nerve specimens were harvested from five cadavers. Cross-sections were examined under a photomicroscope and morphometric analysis performed. RESULTS There was a significantly greater number of myelinated fibres than unmyelinated ...

following the first report of laryngeal small cell carcinoma in canada in 1972,only 82 cases of this cancer has been reported in the literature untill 2001.this cancer originates from laryngeal neuroendocrine cells.It,s clinical presentation consists of hoarseness,breathing difficulty:and cigarette smoking is the most important risk factor.this type of cancer is mostly presented after 50 years ...

BACKGROUND The purpose of this study was to evaluate the contribution of laryngeal intraoperative nerve monitoring (IONM) during thyroidectomy in predicting postoperative laryngeal mobility. METHODS Between 2009 and 2012, 127 patients underwent thyroidectomy, during which 216 recurrent laryngeal nerves were stimulated with suprathreshold stimulations. Laryngeal mobility was examined through d...

Laryngeal schwannomas are rare, benign tumors, most often arising from the superior laryngeal nerve. We describe a case of a 68-year-old female with a laryngeal schwannoma of the recurrent laryngeal nerve after traumatic injury. We postulate that trauma to the recurrent laryngeal nerve during thyroidectomy or thyroplasty incited growth of a nerve sheath tumor. This is the first reported case of...

The incidence of laryngeal sarcoma is exceedingly low with osteosarcomas of the larynx being rarer still, comprising less than 1% of all associated malignancies. To date, only 32 cases have been reported since this pathologic entity was first described in 1942. In this article, we discuss the most recent case of laryngeal osteosarcoma in a patient presenting with respiratory distress found to b...

Tsai, Tung-Lung, Shyue-Yih Chang, Chin-Yin Ho, and Yu Ru Kou. Neural and hydroxyl radical mechanisms underlying laryngeal airway hyperreactivity induced by laryngeal acid-pepsin insult in anesthetized rats. J Appl Physiol 101: 328 –338, 2006; doi:10.1152/japplphysiol.00064.2006.—Laryngopharyngeal or gastroesophageal reflux is associated with laryngeal airway hyperreactivity (LAH), but neither t...

BACKGROUND Granulocytic sarcoma is an extramedullary tumor of myeloblasts. The purpose of this report was to present a case of a primary laryngeal granulocytic sarcoma and review of the literature. METHODS A literature review was performed using Medline and PubMed databases to search for cases of all primary and secondary myelogenous tumors of the larynx. RESULTS A 36-year-old man presented...

Extramedullary plasmacytoma (EMP) is a rare plasma cell neoplasm that occurs mainly in the soft tissues of head and neck region, with the paranasal sinuses, nasal cavity and nasopharynx being the most common sites. Solitary EMP of the larynx is very rare but increasingly reported recently. Common sites of involvement in larynx in the order of frequency are the epiglottis, ventricles, vocal fold...

the laryngeal mask airway (lma) is an important addition to the anesthetist's equipments. however, its usage may involve some complications. we have encountered an unusual and potentially serious complication using this equipment. a 45-year old man underwent cataract surgery under general anesthesia. after the induction of anesthesia, a size 4 of the reusable classic lma was inserted without an...
