目的探讨下斜方肌皮瓣在颊部恶性肿瘤术后大型组织缺损修复重建中的作用。方法2000年1月至2004年1月应用以颈横动脉为血供的下斜方肌皮瓣对颊部恶性肿瘤根治性切除后的缺损进行一期整复7例,其中2例皮瓣折叠修复颊部洞穿缺损。皮瓣最大为8 cm×7 cm。结果7例皮瓣术后全部存活,所有伤口愈合良好,术后随访6～24个月,全部皮瓣无坏死,头颈部形态功能满意。结论下斜方肌皮瓣面积大,血管蒂较长,血运可靠,操作简便,而且柔软较薄,适合修复面颊部恶性肿瘤根治性手术后巨大缺损。
Objective To investigate the role of inferior trapezius myocutaneous flap in repairing and repairing large tissue defects after malignant cheek surgery. Methods From January 2000 to January 2004, 7 cases of radical resection of cheek malignant tumor were treated by transplanted inferior trapezius myocutaneous flap with transverse cervical artery. One case was reconstructed in 2 cases with flap flaps Repair cheek hole through the defect. Flap up to 8 cm × 7 cm. Results All the 7 flaps survived postoperatively and all the wounds healed well. All patients were followed up for 6-24 months. All the flaps were free of necrosis and the morphology of the head and neck was satisfactory. Conclusions The lower trapezius muscle flap has large area, long vascular pedicle, reliable blood supply, simple operation, and is soft and thin, which is suitable for repairing giant defects after radical surgery of cheek malignant tumors.
