摘　　要：目的　探讨应用多孔高密度聚乙烯 (Medpor)支架耳廓再造的方法 ,提高耳廓再造的形态效果。方法　以Medpor为支架 ,采用耳后乳突区皮肤扩张术 (Ⅰ式 )和颞筋膜瓣并皮片移植术 (Ⅱ式 )两种方法施行全耳廓再造共 112例。其中 ,2 3例采用Ⅰ式手术 ,分两期完成耳廓再造 ;89例采用Ⅱ式手术 ,Ⅰ期完成耳廓再造。结果　 112例中 ,成功 10 9例 ,再造耳廓形态较满意 ;失败 3例。该组病例共发生Medpor支架外露 17例 ,其中采用Ⅰ式手术组发生 8例 ,占该组病例的 34% ,采用Ⅱ式手术组发生 9例 ,占该组病例的 10 %。 14例均经Ⅱ期手术用局部皮瓣或局部筋膜瓣并皮片移植获修复 ,3例因支架严重外露无法修复而取出。结论　Medpor支架是耳廓再造可供选择的一种组织代用品 ,用于耳廓再造可取得较好的形态效果。Objective To study the methodology of the ear reconstruction using Medpor framework. Methods Using Medpor material as ear framework, 112 cases of ear reconstruction were performed using the expanded skin flap on the mastoid region(method Ⅰ) and the temporal fascia flap adding skin graft ( method Ⅱ) to cover ear framework. Twenty-three cases adopted method Ⅰand 89 cases adopted methodⅡ. Results One hundred and nine cases of the reconstructed ear were successful with a good appearance and 3 cases were failure. The exposure of Medpor framework occurred in 17 cases in this series. Among them the method Ⅰ occurred in 8 cases (34 %) and the method Ⅱ was used in 9 cases (10%). The exposure of Medpor framework in 14 cases were repaired using local skin flap or local fascia flap and skin graft. In 3 cases Medpor framework had to be removed due to the sever exposure. Conclusion It seems that Medpor framework is a good alternative for the ear reconstruction.
