Stenosis of the larynx is more frequent than tracheal stenosis; in a review of 752 cases of stridor seen at The Hospital for Sick Children, Great Ormond Street, London, laryngeal pathology accounted for 88% of the cases (Evans, 1986). The major cause of airway obstruction was as a result of congenital anomalies of the larynx and trachea. Holinger (1980) noted in his review of 219 patients with ...

Laryngotracheal invasion worsens the prognosis of thyroid cancer and the surgical approach for laryngotracheal invasion is controversial. In this paper, partial full-thickness excision of the cricoid cartilage with supracricoid laryngectomy and reconstruction of existing defect with thyroid cartilage are explained in a patient with papillary thyroid carcinoma invading the thyroid cartilage and ...

Introduction. The nonsquamous carcinomas of the larynx are considered rare with the majority of malignant tumors in this area, reaching the rate of 95%, to be squamous cell neoplasms. Case Report. The case refers to a 53-year-old man that presented with symptomatology of motor nerve disease. During the evaluation of the neurologic disease, a subglottic mass of the larynx was revealed accidental...

Echolocating bats have adaptations of the larynx such as hypertrophied intrinsic musculature and calcified or ossified cartilages to support sonar emission. We examined growth and development of the larynx relative to developing flight ability in Jamaican fruit bats to assess how changes in sonar production are coordinated with the onset of flight during ontogeny as a window for understanding t...

Larynx cancer is the second most common type of cancer among all head and neck cancers. Deregulation of epigenetic effectors, including altered expression of histone methyltransferases from the MLL (mixed lineage leukemia) family, have been reported in many cancer types, yet little is known concerning their involvement in larynx cancer. Our objective was to determine the expression profile of M...

In order to support swallowing, the efficacy of functional electrical stimulation for different stimulation settings of the submental musculature has been investigated. The stimulation was administrated at rest and synchronously to voluntary initiated swallows. The onset of a swallow was detected in real-time by a combined electromyography/ bioimpedance measurement at the neck in order to trigg...

Object: The therapeutic options for advanced laryngeal-hypopharyngeal cancer have broadened in the last decades, in the attempt to cure the cancer sparing laryngeal functions and to improve quality of life (functional surgery, chemoradiotherapy, combined therapy). Methods: We propose a single-centre based retrospective study on the results of the treatment of larynx-hypopharynx cancer on the ba...

Over the past decades, randomized clinical trials have assessed and validated the concept of larynx preservation. This new concept has obviously modified the treatment algorithm for laryngopharyngeal squamous cell carcinoma. However surgery for larynx and hypopharynx cancer remains indicated in many cases. Initial partial surgery is indicated for early diseases. This surgery may be performed en...

OBJECTIVES/HYPOTHESIS To examine the current body of literature supporting the role of the larynx in adult obstructive sleep apnea (OSA). DATA SOURCES PubMed. METHODS PubMed search using medical subject headings "larynx" and "obstructive sleep apnea." Original articles in English related to adult patients were initially included, and the bibliographies of pertinent articles were hand-search...

Muscular tension dysphonia, episodic laryngospasm, globus, and cough may be considered to be hyperfunctional laryngeal symptoms. Suggested etiological factors for these symptoms include gastroesophageal reflux, psychological problems, and/or dystonia. We propose a unifying hypothesis that involves neural plastic change to brainstem laryngeal control networks through which each of the above etio...
