1978年3月以来,作者对梨状窝癌采用了保守性喉咽切除术。用以整复喉咽缺损的方法是颈部皮瓣、胸三角皮瓣、游离微血管肠段移植、胸大肌皮瓣及胃上提等。喉的残存部分以颈部皮瓣、胸舌骨肌筋膜、会厌或残存会厌整复,使喉的功能,即发音、吞咽保护和呼吸全部恢复或恢复发音及吞咽保护部分功能。治疗的47例梨状窝癌患者获得了较好的治疗效果,5年存活率为41.7%,3年存活率50%,喉功能完全恢复31例,部分恢复16例。作者认为保留喉的未被累部分是可行的。不影响肿瘤切除的彻底性。
Since March 1978, the authors used conservative laryngeal resection for piriform carcinoma. The method used to reconstruct the hypopharyngeal defect is neck flap, thoracic triangle flap, free microvascular intestine graft, pectoralis major myocutaneous flap, and gastric uplift. The remaining part of the larynx is repaired with neck flaps, thoracic levator fascia, epiglottis, or residual epiglottis, so that the function of the larynx, ie, pronunciation, swallowing protection, and respiration can all be restored or restored, and some functions of swallowing can be protected. 47 cases of patients treated with pyriform sinus cancer had better therapeutic effects, with a 5-year survival rate of 41.7%, a 3-year survival rate of 50%, a complete recovery of laryngeal function in 31 cases, and a partial recovery in 16 cases. The author thinks that it is feasible to keep the untired part of the throat. Does not affect the thoroughness of tumor resection.
