Application of O-Z skin flap for repairing skin defect of lumbosacral area

目的：探讨应用O-Z皮瓣修复腰骶部皮肤缺损的临床疗效。方法：于局麻下进行手术，距腰骶部皮损边缘0．5-2．0cm完整切除皮损后．在缺损区周边正常皮肤设计O-Z皮瓣，修复创面。结果：12例患者中，缺损面积最大10．2cm×6．5cm，最小3cm×2．7cm,术后伤口均Ⅰ期愈合，皮瓣全部成活，术后随访3～12个月，无感觉异常，皮损无复发。结论：应用O-Z皮瓣修复腰骶部皮肤肿瘤扩大切除后所形成的缺损，皮瓣张力小，血运丰富，易于成活，耐摩擦，且皮瓣区与周嗣皮肤颜色一致，瘢痕不明显．是腰骶部较大皮肤缺损修复的一种优选方法，适合临床推广应用。

Objective： To investigate the therapeutic efficacy of O-Z skin flap for repairing the skin defect of lumbosacral area. Methods： Under local anesthesia, the malignant tumor of lumbosacral lesions were reseeted completely 0.5-2.0 cm away from the edge. For recovering the wound, the O-Z skin flap was designed according to the normal skin surrounding the defect. Results： Among 12 patients, the largest area of lumbosacral skin defeet was 10.2 cm × 6.5 cm, while the smallest was 3 cm × 2.7 cm. After operation, the wound was healed by first intention, and all flaps survived. The patients were followed up for 3-12 months, no relapse of the tumor, and no abnormal sensation of the skin flap were observed. Conclusion： The O-Z skin flap can repair the lumbosacral skin defect with minimal tension, sufficient blood supply, which facilitate the flap survival. And the color of the flap area was the same as the surrounding skin. The scar formed was inconspicuous. Therefore, it is a good method to repair a large area of lumbosacral skin defect, and suitable for clinical application.
