对18例晚期口咽侧壁肿瘤患者的术后缺损，用胸大肌肌皮瓣修复。取瓣面积为15cm×10cm～3cm×3cm；3例发生部分坏死，4例行预防性气管切开；术后外形及口咽功能恢复均满意。术后3年和5年生存率分别为61．5％和40．0％。皮瓣的愈合与本前放疗及术中操作等因素有关。认为晚期口咽侧壁肿瘤术后缺损应首选胸大肌肌皮瓣作一期修复，以提高患者生存质量，延长其生命。
The pectoralis major myocutaneous flap was used to repair the postoperative defect of 18 patients with advanced oropharyngeal wall tumors. The flap area was 15cm×10cm～3cm×3cm; partial necrosis occurred in 3 cases and prophylactic tracheotomy was performed in 4 cases; the postoperative shape and recovery of oropharyngeal function were satisfactory. The 3-year and 5-year survival rates were 61.5% and 40.0%, respectively. Flap healing is related to factors such as previous radiotherapy and intraoperative operation. It is considered that the pectoralis major myocutaneous flap should be used for primary repair of patients with late oropharyngeal lateral wall tumors after surgery to improve the quality of life and prolong life.
