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 ...

Vocal fold paralysis is associated with involvement of the vagus nerve or the recurrent laryngeal nerve between the jugular foramen and the entry point into the larynx. Malignancies of the thyroid are a frequent cause, but vocal fold paralysis is also found in certain benign diseases. In a series of 1,200 cases, the incidence of the association between paralysis and benign thyroid disease was 0...

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...

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...

Statement of Problem. Laryngocele is a rare laryngeal disease, where there is an abnormal dilatation of the saccule of the laryngeal ventricle. It can either be internal or external, and a laryngopyocele is a rare complication of this anomaly. Internal laryngopyoceles can prove difficult to manage, as they often present with airway compromise. Method of Study. Case Report. Results. We present a...

OBJECTIVES This report provides a detailed knowledge base of individual subject laryngeal cartilage dimensions across multiple species to assist researchers in creating subject-specific biomechanical laryngeal models. METHODS The raw data from previous laryngeal cartilage studies were grouped by species (for human, canine, and ovine) and by cartilage (arytenoid, thyroid, and cricoid) by means...

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...
