BACKGROUND Laryngeal hypersensitivity may be an important component of the common disorders of laryngeal motor dysfunction including chronic refractory cough, pdoxical vocal fold movement (vocal cord dysfunction), muscle tension dysphonia, and globus pharyngeus. Patients with these conditions frequently report sensory disturbances, and an emerging concept of the 'irritable larynx' suggests comm...

Introduction: Cigarette smoking and alcohol consumption have a well-known effect on the development of upper aerodigestive tract carcinomas, but such a role for opium is questionable. This study was designed to assess the correlation between opium inhalation and cancer of the larynx and upper esophagus. Materials and Methods: Fifty eight patients with laryngeal cancer, ninety eight patients wit...

Background & Objective: Laryngeal squamous cell carcinoma (LSCC) is considered to be one of the most common cancers of the head and neck, accounting for roughly 90% of all malignant tumors of the larynx. To have a timely diagnosis for a better and practical therapy, molecular markers have to be investigated. The aim of this study was to determine the expression of Cyclin D1 (CD...

Introduction: Laryngeal cancer is the second most common cancer involving the respiratory tract, second only to lung cancer. Previous studies have shown opium dependency to be a possible risk factor for laryngeal cancer. Opium consumption is a major problem in some parts of the world. The aim of this study was to investigate the effect of opium consumption on the pattern of involvement in laryn...

BACKGROUND Bleeding within the supraglottic region can be a lethal complication after CO(2) laser microsurgery. Our aim was to propose endoluminal anatomical landmarks to locate the superior laryngeal vessels resulting in a safer microsurgery. METHODS Endoluminal dissections were made in 22 larynges without laryngeal disease. RESULTS The neurovascular structures were in the superior third o...

introduction:dystonia is a disorder of movement caused by various etiologies. laryngeal dystonia is caused by the spasm of laryngeal muscles. it is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. the pathophysiology of this type of dystonia is not fully known. some researchers have suggested that basal ganglia structure...

Masamitsu Hyodo, Takahiko Yamagata, Kazumi Motoyoshi and Aki Taguchi Recurrent laryngeal nerve paralysis in children is a relatively rare disease. Its clinical features in children are considered dissimilar to those in adults. Here we present 11 cases of children with recurrent laryngeal nerve paralysis and discuss the manner of treatment for this disease. Clinical features compared and found t...

PURPOSE To verify the accuracy of clinical evaluation compared with videofluoroscopic swallowing studies in the detection of isolated laryngeal penetration and laryngeal aspiration in children with suspected dysphagia; to identify clinical signs and symptoms associated with isolated laryngeal penetration and laryngeal aspiration; and to determine the sensitivity and specificity of the clinical ...

1.1.1. Indirect laryngoscopy Knowing that almost all laryngeal and tracheal diseases are visible at the surface of the mucous membranes it is of particular interest to visualize these structures. Endoscopic examinations of the larynx and the trachea are essential in the otorhinolaryngo‐ logical field and had their beginning over 200 years ago. Before the 1800`s only autopsy specimen could clari...

Introduction The larynx of the horse is part of the upper airway and serves as a conduit between the pharynx and the trachea, or the wind pipe that takes inspired air to the lungs for gas exchange. The larynx is comprised of a number of cartilages that work together to allow for increased airflow during exercise and to close the trachea during swallowing to prevent foreign material and food par...
