摘要目的 探讨应用指背血管网皮瓣修复手指皮肤缺损的方法及临床疗效.方法 2005年8月至2010年8月,采用指背血管网皮瓣修复2～5指皮肤缺损49例61指,其中示指23指,中指19指,环指16指,小指3指.末节指端皮肤缺损42指,中节皮肤缺损12指,近节皮肤缺损7指.皮瓣切取面积最大为27 mm×20 mm,最小为10 mm×8 mm.结果 49例61指皮瓣全部成活,其中52指获6 ～ 22个月随访,皮瓣外观及手指功能恢复满意.皮瓣感觉恢复达S3,两点辨距觉6～9 mm,平均7.6 mm.供区无并发症.结论 指背血管网皮瓣具有血供可靠、不牺牲主要血管,操作简便、安全,术后效果满意,是修复手指皮肤缺损较为理想的方法.

abstractsObjective To investigate the therapeutic effect of digital dorsal flap based on vascular network for skin defects at fingers.Methods From August 2005 to August 2010,49 cases with 61 skin defects at fingers were treated with the digital dorsal flaps,including 19 at the index fingers,19 at the middle fingers,16 at the ring fingers and 3 at the little fingers.The defects were 42 at the distal end,12 at the middle segment and 7 at the proximal segment.The flaps size ranged from 27 mm × 20 mm to 10 mm ×8 mm.Results 61 flaps in 49 cases survived completely.52 fingers were followed up for 6-22 months.The aesthetic and functional results were both satisfactory.The flaps sensation was graded as S3,with a discrimination distance of 6-9 mm (median, 7.6 mm ). No complication happened in donor sites.Conclusions The digital dorsal flap based on vascular network has reliable blood supply with less morbidity to the main artery.It is safe and easily performed with good effect for skin defect at finger.
