耳后乳突区皮肤扩张法在全耳廓再造术中的应用

The rebuild auricle with Medpor on expanded skin flap of the mastoid process area

目的:探讨采用耳后乳突区皮肤扩张皮瓣用于全耳廓再造术的方法及临床效果。方法:36例先天性小耳畸形作全耳廓再造术,Ⅰ期先在患侧耳后乳突区皮下置入50ml肾形皮肤软组织扩张器3～5个月至预期皮肤面积,然后Ⅱ期手术将此皮瓣覆盖于整个Medpor支架表面,再造外耳廓。结果:36例再造耳廓皆成功,皮肤血运良好,厚薄均匀适中,肤色正常,立体感强,形象逼真。结论:全耳廓再造术采用耳后乳突区扩张皮瓣可解决预期所需的覆盖皮瓣的质和量,是手术成功的关键步骤。

Objective To study on the method and results on the rebuild auricle with Medpor on expanded skin flap of the mastoid process area. Methods Thirty-six cases with congenital vestigial auricles： Ⅰ stage, put the 50ml kidney skin parenchyma dilater under the auricle mastoid process area for 3-5 months. Ⅱ stage, the skin flap covers the Medpor＇s surface to rebuild the new auricle. Results All 36 cases are successful： good blood supply, normal colour, good third dimension and vivid shape. Conclusion It shows that using the expanded skin flap of the mastoid process area is a feasible and key step for the rebuild auricle opration.
