应用耳后扩张皮瓣及多孔高密度聚乙烯支架行儿童全耳廓再造

目的 探讨儿童先天性小耳畸形采用耳后扩张皮瓣及多孔高密度聚乙烯(Medpor)支架做全耳廓再造的方法和效果.方法 对30例年龄5～16岁先天性小耳畸形患者,采用耳后皮肤扩张及Medpor支架法行全耳廓再造术.结果 30例皆获成功,再造耳廓肤色正常,形态与位置与健侧基本对称.但其中11～16岁组的5例中,有2例扩张的皮瓣面积略有不足,需另以小块局部筋膜瓣和皮片移植补充;而5～10岁组的25例,扩张的皮瓣面积皆足以包裹整个Medpor支架,无需另外植皮.结论 本术式的手术时机选择最好在10岁以前,一是避免患儿因小耳畸形受到社会讥讽造成的心理创伤,二是耳廓发育已接近成熟,耳后皮肤扩张皮瓣面积已足敷再造之需.

Reconstruction of auricle with expansive skin flap and Medpor framework in childhood

Objective To study the methodology and results of the auricle repair with expanded skin flap in mastoid process area and Medpor support in children with congenital malformation.Methods Thirty cases of congenital malformation were enrolled with age ranged from 5～16 years old.Whole auricles were all reconstructed with an expanded skin flap in mastoid process area and Medpor support.Resuits In all successful cases.their repaired auricles had the natural complexion and profile,and the positions were symmetric with healthy one,but in 2 cases(age group of 11-16 years),the expanded skin flap had less skin grafting.Conclusion It is suggested that optional operation time might be selected before 10 years old,because their psychological trauma could be avoided owing to microtia and in that age the size of the expanded flap is larger enough to reconstruct the ear as their auricle iS well-developed.
