摘要
对60具成人尸体喉标本进行了观察与测量,发现半数标本的双侧声带稍不对称,声带并非总是固定于尸状位.通过对声带、小角软骨和构状软骨及其相互关系的形态学分析,认为小角结节可能为声门运动的缓冲袋置,单侧小角结节病变,可引起两侧声带不在同一平面上闭合,双侧小结结节病变,可能导致喉接触性渍疡和声门闭合时后端出现三角形缝隙.
The samples of 60 larynxes of adult cadevers were studied. We found that two sides of the vocal folds are sloghtly asymmetric and aren't alwasys fixed in cadaveric position in 50% samples. By analysing vocal folds, cornicalate cartilages and arytenoid cartilages, together with the relationship between them, we come to the conclusions as follow: (1) cormiculate nodi acts as an elastic cushion in the movement of glottis; (2) the diseases of the unilateral corniculate node could result in uneven closing of bilateral vocal folds; (3)the diseases of bilateral corniculate nodi could cause contact ulcers of the larynx and a triangular split in posterior part of the glottis when it closing.
