摘要
目的 探讨皮肤扩张器的定量扩张法在在耳廓再造中的应用，并对所发生的并发症进行处理。方法选择50ml肾形扩张器埋置于残耳后乳突区无毛发皮下，术后3d拔除引流管，10d拆除缝线。术后7d进行常规注水，每周3次，每次注水约5ml，注水总量为60ml左右。注水完毕后维持扩张1个月。结果1992年1月至2006年12月共收治先天性小耳畸形患者5248例，完成50ml。肾形扩张器埋置6252只。扩张器维持扩张完毕后可见扩张皮肤质薄、血管丰富。并发症有血肿、扩张器外露、创口裂开、感染等，发生率较低，约为7．79％。结论皮肤定量扩张法操作简单、并发症较少，为耳廓再造提供了良好的无毛发、质薄、血供丰富可靠的皮肤。
Objective To explore the application of tissue expander in ear reconstruction and to deal with the complications. Methods 50 ml kidney-shape tissue expanders were implanted subcutaneously in the mastoid area. The drainage tube was removed 3 days after operation. The suture was removed 10 days later. Since 7 days after operation, 5 ml NS was injected into the expander every time, three times a week. The total injection volume was about 60 ml. After that, the expander was maintained for one month. Results From January 1992 to December 2006, 5 248 patients of microtia were treated with 6 252 expander. After the maintaining period, the expanded skin was thin and well-vascularized. The complication rate was 7.79%, including hematoma, malunion and infection. Conclusions The quantitative tissue expansion is easily manipulated with few complications. It can provide hairless, thin skin with reliable blood supply for ear reconstruction.
