arytenoid

By examination, 56 patients were found congestion and tumefaction in epiglottis lingual surface, 26 patients were found high ball-like swelling in epiglottis, 6 patients had epiglottic vallecula mucosa aryepiglottic plicae, arytenoid cartilage swelling, 14 patients had epiglottic tumefaction, 1 case had laryngeal abscess.

检查见会厌舌面明显充血肿胀56例，会厌高度肿胀似球形26例；伴有会厌谷黏膜、杓会厌皱襞、杓状软骨红肿6例；

Method: Seven cases with laryngeal carcinoma ( T 3N 0M 0) were treated with secondary total laryngectomy. The arytenoid cartilage of the healthy side and interarytenoid fold were remained. A laryngeal phonatory tube with sphincteral function was constructed with arytenoid cartilage and hypopharyngeal mucosa.

方法：7例喉癌病变范围T3N0M0行次全喉切除术，术中保留健侧的披裂软骨及杓间区粘膜，用披裂软骨与下咽粘膜制作具有括约功能的喉发声管。

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；
