为探讨简便易行、损伤小的下咽成形方法，选择下咽侧后壁癌或梨状窝外侧壁肿瘤，用患侧单、双蒂胸锁乳突肌皮瓣修补咽、舌根缺损。结果：梨状窝癌Ｔ３Ｎ１Ｍ０３例，肿瘤切除后采用胸舌骨肌筋膜修补患侧室带、声带缺损，双蒂胸锁乳突肌皮瓣修补外侧壁缺损。吞咽功能正常，２例拔除套管，１例带小管呼吸。Ｔ４Ｎ１Ｍ０１例采用单蒂胸锁乳突皮瓣修补咽侧壁及舌根，术后轻度误咽，呼吸、发音功能正常。提示用胸锁乳突肌皮瓣修补咽侧壁缺损效果良好
In order to investigate the easy and less invasive method of hypopharyngeal formation, the hypopharyngeal posterior wall cancer or peloid fossa lateral wall tumor was selected. The unilateral and double pedicled sternocleidomastoid myocutaneous flaps were used to repair the pharyngeal and lingual root defects. RESULTS: T3N1M03 cases of piriform sulcus carcinoma were treated with thoracodorsal muscle fascia to repair the ventricular zone and vocal cord defects, and double-pedicle sternocleidomastoid myocutaneous flaps were used to repair the lateral wall defects. Swallowing function was normal, 2 cases were removed from the cannula, and 1 patient was breathing with a small tube. In the T4N1M01 case, a single pedicled sternocleidomastoid skin flap was used to repair the pharyngeal wall and the tongue base. After operation, the aspiration was slight, and the breathing and pronunciation functions were normal. Tips to repair pharyngeal wall defect with sternocleidomastoid myocutaneous flap
