Characteristics of Glottic Closure Reflex in a Canine Model
PURPOSE The most important function of the larynx is airway protection which is provided through a polysynaptic reflex closure triggered by the receptors in the glottic and supraglottic mucosa, evoking the reflex contraction of the laryngeal muscles especially by strong adduction of vocal cords. Based on the hypotheses that central facilitation is essential for this bilateral adductor reflex an...
متن کاملLaryngeal electromyography in dysphonic patients with incomplete glottic closure.
UNLABELLED The lack of specificity in laryngoscopical examination requires that the diagnosis of superior laryngeal and recurrent laryngeal nerve involvement be carried out with the aid of electromyography. OBJECTIVE This study aims to assess the electrophysiological function of the superior and inferior laryngeal nerves by measuring the electrical activity of the muscles they innervate in dy...
متن کاملPharyngoglottal closure reflex: identification and characterization in a feline model.
Earlier studies in humans have shown that pharyngeal stimulation by water at a threshold volume induces a brief vocal cord adduction, i.e., pharyngoglottal closure reflex. The present study was undertaken to 1) develop a suitable animal model for physiological studies of this reflex and 2) delineate its neural pathway and effector organs. Studies were done in cats by concurrent videoendoscopy a...
متن کاملForced eye closure-induced reflex seizure and non-ketotic hyperglycemia
We report an uncommon case of 53-year-old female patient with partial seizure induced by forced voluntary eye closure due to non-ketotic hyperglycemia. The initial laboratory tests showed an elevated blood glucose level of 550 mg/dL but no evidence of ketosis. Brain magnetic resonance imaging was normal. When the blood glucose levels decreased slowly to about 150 mg/dL in five days, the seizure...
متن کاملThe role of sex in glottic closure pattern in people with normal voice
Background and Aim: Glottic closure pattern is one of the most important stroboscopic signs in judging the normality of laryngeal function. According to the recent researches, complete glottic closure is not the only pattern in normal phonation. The aim of this study was to investigate the glottic closure pattern in normal subjects and to understand the role of sex in having different glottic c...
