目的探讨口轮匝肌为蒂肌黏膜瓣在唇癌切除术后创面修复中的应用。方法切除肿物,根据缺损的大小逆行设计蒂在同侧的口轮匝肌黏膜瓣180°旋转修复创面缺损。结果唇部肿物扩大切除术后,黏膜缺损最大面积约4.0cm×1.0cm,设计口轮匝肌为蒂肌黏膜瓣修复缺损,肌黏膜瓣全部存活,随访3~12个月,肌黏膜瓣存活良好,与邻近唇黏膜无明显色差,且无明显并发症。结论肿瘤切除致唇部组织缺损达到1/3~1/2唇黏膜时,与Abbe瓣相比,以口轮匝肌为蒂肌黏膜瓣修复唇部缺损,术后不需二期断蒂,供区切口隐蔽,术后功能及外观满意,是唇缺损修复的一种新方法,值得临床应用。
Objective To investigate the application of the orbicularis oris muscle pedicle mucosa flap in wound repair after lip cancer resection. Methods The tumors were resected and retrogradely designed according to the size of the defect. A 180 ° rotation of the orbicularis oculi muscle flap on the same side was used to repair the wound defect. Results After the expansion of the lip and the tumor, the maximal mucosal defect area was about 4.0cm × 1.0cm. The orbicularis muscle was designed as the pedicle flap to repair the defect. The mucosal flap survived for 3 ~ 12 months. The musculocutaneous flap Survival well, with no significant difference between the adjacent lip mucosa, and no significant complications. CONCLUSION: When the lip defect caused by tumor resection reaches 1/3 to 1/2 of the lip mucosa, the lip defect is repaired by the orbicularis oris muscle mucosal flap compared with Abbe flap, For the incision hidden area, postoperative function and appearance satisfactory, is a new method of lip defect repair, it is worth clinical application.
