The nerves of the posterior cricoarytenoid muscle arose from the anterior branch and the interarytenoid ramus which was the one of the subdivisions of the anterior branch. 环杓后肌神经来自前支和前支的分支&杓间肌支,支数多,长度短。
The internal branch of the superior laryngeal nerve ( ISLN) innervated not only the supraglottic mucosa but also the interarytenoid ( IA) muscle and the subglottic mucosa. 喉上神经内支不仅支配声门上粘膜,也支配杓间肌(包括的横肌和杓斜肌)和声门下粘膜。
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。
Lateral cricoarytenoid muscle, posterior cricoarytenoid one, thyroarytenoid and interarytenoid ones were often invaded. 环杓侧肌、环杓后肌、甲杓间和杓间肌经常受侵;
