扩张皮瓣联合Medpor耳支架全耳再造的临床研究(附8例报告)

目的:应用扩张皮瓣联合Medpor耳支架行全耳再造术,使耳再造成形逼真,立体感强,手术时间缩短,减少创伤,探讨如何防治Medpor耳支架外露。方法:先在耳缺损区埋置扩张器,定期注水,扩张两个月后,取出扩张器。将Medpor耳支架依照健侧耳廓为模型进行雕刻,塑形后,置入耳缺损区扩张皮瓣后面(耳后乳突区),耳支架后缘用颞浅筋膜瓣及耳后筋膜瓣包埋,植皮,全耳再造成功。结果:共完成此手术8例(男6例,女2例),耳成形良好,手术效果满意,扩张皮瓣覆盖组织与Medpor耳支架贴合紧密,且外形显现良好,耳廓形态逼真。其中仅1例耳支架后方绿豆大小外露,经局部修复痊愈。结论:扩张皮瓣联合Medpro耳支架全耳再造术,形态逼真,立体感强,耳廓形态稳定,远期不易变形,与使用肋软骨支架相比,无切取肋软骨之苦,且手术时间明显缩短。不足:MedPor耳支架价格昂贵,弹性较差,易外露。

Total Auricle Reeonstruction Using by Medpor Graft and Expanded Skin Flap

Objective To discuss the feasibility and the complication of total auricle reconstruction using by Medpor graft and expanded skin flap. Methods: 8cases of patients have been cured by the method: The first stage is to expand the ear. Results:7 of 8 patients have got satisfactory effect without complication ; 1 of 8 patients have alse got satisfactory effect after the complications of exposed. Medpor graft had been cured. Conclusion: It is a satisfactory method to reconstruct total ear, even we should noticed and alerted the complications.
