目的:探讨口底癌临床治疗方法和术中缺损的修复。方法:对9例口底癌病例临床资料进行回顾性分析,其中8例进行口底颌颈联合根治术,有3例术创缺损采用前臂游离皮瓣、胸大肌肌皮瓣修复,伴有下颌骨节段缺损病例采用联合重建钛板进行修复。结果:9例口底癌患者中,除1例有肺、肝转移接受化疗外,8例术后下颌部、颈部和口底部等形态及功能恢复良好,前臂游离皮瓣、胸大肌肌皮瓣全部成活,术后随访2月～11年,未见肿瘤复发或淋巴结转移。结论:口底癌对下颌骨的侵犯与否决定下颌骨切除的术式,胸大肌肌皮瓣是修复口底癌术创巨大缺损的理想方法,联合重建钛板可I期修复下颌骨节段性缺损。
Objective: To explore the clinical treatment of oral floor cancer and repair of intraoperative defects. Methods: The clinical data of 9 cases of mouth cancer were retrospectively analyzed. Among them, 8 cases underwent mouth and neck combined with radical mastectomy. There were 3 cases of forearm free flap and pectoralis major myocutaneous flap repair, Mandibular segmental defects were reconstructed with titanium plate. Results: Of the 9 patients with oral floor cancer, the morphology and function of the mandibular, neck and mouth at the bottom of the 8 patients recovered well except for one case with lung and liver metastasis undergoing chemotherapy. The free forearm flap and pectoralis major muscle All flaps survived, followed up for 2 months to 11 years, no tumor recurrence or lymph node metastasis. Conclusion: The invasion of mandibular floor by oral floor carcinoma determines the surgical procedure of mandibular resection. The pectoralis major myocutaneous flap is an ideal method to repair the huge defect of floor-flap carcinoma. Combined reconstruction of titanium plate can repair the mandibular segment Sexual defects.
