【摘 要】 目的：为提高全喉切除术后用发音管发音重建的成功率提供解剖学基础。方法：对40具(男30，女10)成人标本环咽肌进行解剖，观测左右侧喉下神经入喉处与甲状软骨下角的距离、喉下神经和环咽肌的关系。结果：喉下神经入喉点距甲状软骨下角的距离，左侧(5.5±1.4) mm；右侧(5.3±1.3) mm。75%(60侧)喉下神经在环咽肌的下方穿入喉部；25%(20侧)喉下神经在环咽肌纤维之间穿入喉部。结论：本研究对于指导环咽肌切断术，诊治环咽肌失驰缓症，探讨喉下神经和环咽肌的关系等有重要的临床意义。

Applied anatomy of the cricopharynegeus muscle and inferior laryngeal nerve for pronunciation restoration after laryngectomy
Objective:To improve the operation of pronunciation restoration after laryngectomy.Methods:The morphology of cricopharynegeus muscle was observed in 40 normal adult cadavers.The distance between the point of the inferior laryngeal nerve entering larynx and the inferior corner of thyroid cartilage were measured.The relationship of inferior laryngeal nerve and cricopharynegeus muscle was observed.Results:The average distance between the point of the inferior laryngeal nerve entering the larynx and the inferior corner of thyroid cartilage was (5.5±1.4)mm on the left,and (5.3±1.3)mm on the right.75%(60 cases) of the inferior laryngeal nerves enter larynx under the cricopharynegeus muscle,while 25% (20 cases) across the cricopharynegeus muscle.Conclusion:The discovery is very significant for the cricophyarnegeus muscle myotomy,diagnosis and treatment of the cricopharynegeus muscle spasm,and research about the relationship of the cricopharynegeus muscle and inferior laryngeal nerve.
