扩张的侧后臀腰部双蒂Ω形皮瓣修复前臂环形瘢痕

Repair of circular scar in the forearm by expanded double-pedicle Ω-shaped flap at the rear flank of bottom-waist

目的 探讨前臂环形瘢痕的修复方法.方法 于侧后臀腰部重叠或延续埋置大容量（400～600 ml）扩张器,形成扩张皮肤后,推进缝合成上下开口的Ω形大皮瓣,再将前臂创面植入皮瓣内,三期断蒂.结果 1998年4月至2009年6月于临床应用8例,皮瓣全部成活,经1～3年随访,皮瓣不臃肿,颜色均匀一致,有感觉恢复,供瓣区留有略增宽的线形萎缩性瘢痕.结论 扩张的侧后臀腰部双蒂Ω形皮瓣是一种修复前臂环形瘢痕的较好方法.

Objective To discuss the method for repairing the circular scar in the forearm.Methods Large expander （400-600 ml） were implanted subcutaneously at the rear flank of bottom-waist in the way of overlapping or continued expansion. After expansion was completed, the horizontal opened Ω-shaped flap was formed by advancement of expanded skin with the two pedicles at the two sides. Then the forearm was tunneled under flap with the wound covered by flap. The pedicles were cut off at the third stage. Results From April 1998 to June 2009, 8 cases were treated with no flap necrosis. The patients were followed up for1 to 3 years with good flap color and thickness. Flap sensory was partially recovered.Linear atrophic scar was left in the donor sites. Conclusions It is feasible to repair forearm circular scar by expanded double-pedicle Ω-shaped flap at the rear flank of bottom-waist.
