人们常根据动物试验得出的理论,去解释人喉麻痹后的解剖状态和生理表现,这是不可靠的。在临床及科研上,单、双侧喉上神经及其分支的麻痹常被忽视。本文介绍60多例喉麻痹之动态相,将有助于认识和诊断各种类型之喉麻痹。重点是单、双侧喉上神经麻痹之解剖和生理表现。从喉之发展史看,最初是括约器官,后进化能发声、讲话器官。支配神经受损引起发声、吞咽、吸入机能障碍。喉受迷走神经之喉上神经及喉返神经支配,喉上神经在结状神经节下方的迷走神经干分出,分为内外支,内支穿过甲舌膜司喉上之感觉和分泌功能;外支含运动纤维,支配环甲肌。喉返神经系运动神经,支配喉内肌,亦司声门、声门下区、气管上部之感觉和分泌功
People often based on the theory of animal experiments to explain the anatomical state and physiological manifestations after throat paralysis, which is not reliable. In clinical and scientific research, the paralysis of single and bilateral upper laryngeal nerves and their branches is often neglected. This article describes the dynamic phase of more than 60 cases of laryngotracheal paralysis, which will help identify and diagnose various types of laryngotracheitis. The focus is on the anatomy and physiology of single and bilateral laryngeal nerve palsy. From the history of the development of larynx, the first is the co-ordination of organs, post-evolution can sound, speech organs. Dominating nerve damage caused by sound, swallowing, inhalation dysfunction. Throat by the vagus nerve on the laryngeal nerve and recurrent laryngeal nerve, the laryngeal nerve in the nodal ganglion below the vagus nerve trunk divided into internal and external branches, the internal branch of the throat through the Achilles senile sensory and secretory functions; Contains exercise fiber, dominate the ring muscle. Recurrent laryngeal nerve motor, innervation of the throat, but also Secretary glottis, subglottic area, the upper part of the trachea sensory and secretory function
