摘要
目的探讨对于肋软骨已发生钙化的先天性小耳或后天性耳缺损患者,以MEDPOR作为再造耳廓支架的可行性。方法手术分为2期,1期是在残耳后埋置皮肤软组织扩张器,扩张皮瓣或瘢痕瓣。2期是以扩张皮瓣、耳后乳突区皮下筋膜瓣、残耳、MEDPOR支架、中厚皮片移植行耳廓再造术。自2009年1月---2014年1月,以此种方法行耳廓再造术34例,男性23例,女性11例,年龄32岁-61岁,均为单侧耳廓再造。结果 34例耳均顺利完成二期耳廓再造手术。术后随访时间,最短2年,最长5年7个月,形态令人满意,支架无外露发生。结论对于肋软骨已发生钙化的先天性小耳或后天性耳缺损患者,MEDPOR支架是较为适合的再造耳廓支架材料。
Objective To investigate the possibility of utility of Medpor framework in ear reconstruction when fac- ing rib cartilage calcification in patients with congenital or acquired microtia. Methods Ear reconstruction was completed in two stages. In the first stage, an expander was implanted behind the remnant ear. The skin or scar flap was formed after a period of expansion. In the second stage, the expanded flap, the fascia flap in the mastoid area, the remnant ear, a Me- dorpor framework and split-thickness skin graft were utilized to reconstruct the ear. From January 2009 to January 2014, 34 patients （23 males, 11 females, aged 32 to 61 years） underwent unilateral ear reconstruction in this manner. Results All the 34 patients successfully completed the two-stage ear reconstruction. The follow-up period ranged from 2 years to 5 years and 7 months. The reconstructed ears were satisfactory to patients. No Medpor framework was exposed or extruded. Conclusion Medpor framework is suitable material in ear reconstruction when the desired rib cartilage is calcified in pa- tients with congenital or acquired microtia.
