摘要目的:探讨采用臀部自由穿支螺旋桨皮瓣修复臀部深度创面的效果。方法:2016年2月—2018年5月，解放军联勤保障部队第940医院烧伤整形外科中心收治各种原因所致臀部皮肤软组织缺损患者27例，其中男19例、女8例，年龄28～70岁。原发病中压疮14例、瘢痕癌7例、低温烫伤2例、脓肿2例、藏毛窦2例，伤后或病变组织切除后深度创面位于骶尾部15例、坐骨结节8例、臀部其他部位4例，创面清创或扩大切除后面积4.0 cm×4.0 cm～12.0 cm×6.0 cm。采用面积为8.0 cm×4.0 cm～16.0 cm×6.0 cm臀部自由穿支螺旋桨皮瓣修复创面，供瓣区选择在创面周边、皮肤较为松弛处，皮瓣均以臀部自由穿支血管为轴，螺旋桨式转移修复创面，供瓣区直接拉拢缝合。记录皮瓣成活情况、并发症发生情况、随访情况。结果:27例患者皮瓣均100%成活。2例患者皮瓣因引流不畅，术后2～6 d皮瓣下形成淤血，经换药引流，14～18 d愈合；其余病例皮瓣于术后10～14 d拆线，创面愈合。随访2～12个月，皮瓣供受区外形饱满，与健侧差别不大，能够负重。结论:采用臀部自由穿支螺旋桨皮瓣修复臀部深度创面效果好，供区选择在创面周边、皮肤相对松弛部位即可，在修复创面的同时，供瓣区直接拉拢缝合，可保证臀部饱满的外形。

abstractsObjective:To explore the effects of free perforator propeller flap from buttock in repairing deep wound of buttock.Methods:From February 2016 to May 2018, 27 patients with buttock skin and soft tissue defects caused by various reasons were admitted to the Burn and Plastic Surgery Center of the 940th Hospital of the Joint Logistic Support Force of People′s Liberation Army, including 19 males and 8 females, aged from 28 to 70 years. Among the protopathy, there were 14 cases of pressure sores, 7 cases of scar carcinoma, 2 cases of low-temperature scald, 2 cases of abscess, and 2 cases of pilonidal sinus. The wounds were located in the sacrococcygeal region in 15 cases, the ischial tuberosity in 8 cases, and the rest area of buttock in 4 cases after injury or lesion resection. The size of wounds ranged from 4.0 cm×4.0 cm to 12.0 cm×6.0 cm after debridement or extended resection. The free perforator propeller flaps from buttock with areas of 8.0 cm×4.0 cm-16.0 cm×6.0 cm were used to repair the wounds, and the donor sites were selected adjacent to the wounds where the skins were relatively loose. All flaps took buttock free perforator vessels as the axis and were transferred in propeller-type to repair the wounds. The donor sites were directly closed and sutured. The survival, complications, and follow-up of flaps were recorded.Results:All the flaps survived 100% in 27 patients. Congestion formed under flaps 2-6 days post operation in 2 patients due to inadequate drainage, which were healed after dressing change and drainage for 14-18 days. The sutures of flaps in the other cases were removed in 10-14 days post operation, and the wounds were healed. Follow-up for 2-12 months showed that the shapes of flaps and the donor sites were plump, which were not much different from the healthy sides, and the flaps could bear weight.Conclusions:Repairing buttock deep wound with buttock free perforator propeller flap has good effects. The donor site can be designed in the area adjacent to the wound where the skin is relatively loose and can be directly closed and sutured while repairing the wound, which can ensure plump buttock appearance.
