cricoarytenoid

We observed that contraction of posterior cricoarytenoid muscles cause arytenoid cartilages towards external rocking with external gliding along the cricoarytenoid faucets, leading to vocal processes turning up-posteriorly-externally, departing of bilateral arytenoid cartilages, opening the glottis.

环构后肌收缩使杓状软骨外翻跨动，同时沿环构关书面向外侧滑动，导致声带突向后、外、上方旋转，两侧杓状软骨相互远离，声门开大；

Objective: To assess the curative effects of the dislocation of cricoarytenoid joint caused by intubation, indirect laryngoscope ( IL) and direct laryngoscope ( DL) were utilized to the closed reduction of the displaced arytenoid under local anesthesia.

目的：探讨在局麻下经间接喉镜和直接喉镜杓状软骨拨动术对气管插管致环杓关节脱位的疗效。

Contraction of lateral cricoarytenoid muscles cause arytenoid cartilages towards internal rocking, vocal processes to-ward turning down-anteriorly-medially, closing the intermembranous part of glottis.

环杓侧肌收缩使杓状软骨内翻跨动，声带突向前、内、下方旋转，膜间部声门闭合；
