目的探讨胸大肌皮瓣修复口腔颌面部缺损的临床疗效。方法回顾分析本院35例患者的临床资料。结果 35例中全部成活30例,部分成活3例,坏死2例;本组患者肌皮瓣均直接被用作口腔黏膜衬里,1例胸大肌皮瓣作成双叶瓣,折桑串联修复颊癌的皮肤一黏膜洞穿性缺损。结论胸大肌皮瓣以胸肩峰动脉的胸肌支为主要血供,属轴型瓣,血管位置较恒定,血管粗大、标志明确,血运可靠。其并发症的发生主要原因与年龄、性别、全身因素及手术操作有关。其年龄相对越小,成功率就越高;同时精细的手术操作也是手术成功的关键。
Objective To investigate the clinical effect of pectoralis major myocutaneous flap in the repair of oral and maxillofacial defects. Methods The clinical data of 35 patients in our hospital were retrospectively analyzed. Results All of the 35 cases survived 30 cases, 3 cases were partially survived and 2 cases were necrotic. Myofascial flap was directly used as oral mucosa lining and 1 case of pectoralis major myocutaneous flap was double flap, Cancer skin mucosal puncture defect. Conclusions Pectoralis major myocutaneous flap takes the chest branch of thoracoacromial artery as the main blood supply. It belongs to a shaft type flap. The position of blood vessel is relatively constant, the blood vessel is thick, the mark is clear, and the blood supply is reliable. The main causes of complications related to age, gender, systemic factors and surgical operations. The relatively smaller age, the higher the success rate; the same time fine surgical operation is the key to the success of surgery.
