摘要
目的观察改良M形瓣修复下唇癌切除术后缺损的效果,为临床应用提供参考。方法对14例改良M形瓣修复下唇癌术后缺损的临床资料进行回顾性分析,术后随访患者皮瓣存活、张口度、义齿使用及双侧口角对称、复发、生存等情况。结果 14例下唇癌患者进行术后即刻重建,肿瘤切除后缺损范围为下唇的30%~50%。所有患者通过改良M形瓣转移双侧残余口唇组织来重建口轮匝肌的连续性,皮瓣血供稳定,皮瓣完全存活,无出血、感染或皮瓣坏死等并发症;口唇活动及感觉恢复良好:开闭口、发音及饮食功能无明显障碍,平均最大开口度(3.06±0.23)cm;其中3例使用活动义齿患者,义齿可正常摘戴;所有患者口角得以保留,85.7%的患者(12/14)双侧口角基本对称,皮瓣与面部颜色匹配,下唇形态自然美观,瘢痕不明显。术后随访6个月~4年(平均2年6个月),无复发及死亡病例。结论改良M形瓣手术设计简单且易操作,可适用于存留口角的下唇30%~50%的缺损重建。
Objective To observe the clinical effect of the modified M-shaped flap for repairing defects following resection of lower lip cancer and to provide a reference for clinical application. Methods Fourteen cases using modified M-shaped flaps to repair lower lip cancer surgery defects were retrospectively analyzed. The postoperative follow-up patients′ flap survival, mouth opening, denture use, bilateral mouth angle symmetry, recurrence and survival were analyzed. Results Fourteen patients with lower lip cancer underwent reconstruction immediately after surgery, and the defect range after tumor resection was 30% to 50% of the lower lip. The continuity of the orbicularis oculi muscle is reconstructed by modified M-shaped flap to transfer bilateral residual lip tissue. The blood supply to the flap is stable. All patients′ flaps survived completely without complications, such as hemorrhage, infection or flap necrosis, and their lip movement and sensation recovered well. There were no obvious obstacles in opening and closing or pronunciation and dietary function, and the mean maximum opening was(3.06 ± 0.23) cm. Three patients used active dentures, which could be removed normally. All patients′mouths were preserved. Approximately 85.7% of patients(12/14) had bilateral symmetry of the bilateral mouth, the flaps matched the facial color, and the lower lip was naturally beautiful, as the scar was not obvious. After 6 months to 4 years of follow-up(mean 2 years and 6 months), no recurrence or death occurred.Conclusion The modified M-shaped valve design is simple and easy to operate. This method can be applied to 30% to 50% defect reconstructions of the lower lip to retain the corner of the mouth.
