摘要
目的：为提高全喉切除术后患者用发音管发音重建的成功率，选择最能影响发音重建成功的咽下缩肌进行研究。方法：对４０具正常成人尸体标本咽下缩肌的解剖结构进行了详细的观察和测量。测量咽下缩肌各起点处的宽度，在甲状软骨板后缘的厚度；止点的长度；环咽肌后壁的测量；并用组织切片法观察咽缝的结构。结果：发现咽下缩肌不仅有起于甲状软骨和环状软骨的肌纤维，而且有起于第１气管环的肌纤维和肌腱。咽缝不是呈线状，而是呈条带状。结论：对发音重建行咽缩肌切断术有重要的临床意义。
Objective:To raise successful rate of prosthesis of voice restoration for postlaryngectomy patients.Methods:The width of inferior constrictor origin,the thickness of it behind the thyroid cartilage,the length of it stop and cricopharynegeus muscle were observed and measured on 40 adult cadaveric specimens.The pharyngeus raphe was observed with paraffin section method.Results:Not only did inferior constrictor start from thyroid cartilage and cricoid cartilage,but also start from first trachea ring.The pharygeus raphe was observed as a band not line. Conclusions:The discovery is very significant to inferior constrictor myotomy for voice restoration.
