应用多孔高密度聚乙烯为支架的一期全耳廓再造

One stage total auricle reconstruction with a Medpor framwork

目的 探讨多孔高密度聚乙烯(Medpor)生物植入体的组织相容性。寻找外形理想,手术简便的外耳再造新方法。方法 以Medpor为耳廓支架,掀起耳后皮瓣及耳后筋膜瓣,将支架植入两者之间,并按合适的解剖位置固定于耳后乳突区骨膜上。耳后及筋膜组织瓣创面植皮。结果 自1998年3月～2000年12月,应用Medpor为支架一期再造耳廓8例,2例发生支架部分外露,经修补后未再发生外露现象,其余病例形态满意。结论 Medpor生物植入体组织相容性良好。以它做为支架再造耳廓,可免除患者胸部切取肋软骨造成的痛苦和畸形,且形态良好。但该植入体价格贵,质地硬是其不足之处。

Objective To explore the histocompatility of Medpor implant and to find a new method of auricle reconstruction. Methods We improved traditional method of auricle recon-structionby Medpor framework. Firstly, the hair follicle of the postauricular flap was removed at the level of subcutaneous vas-calur net and the postauricular flap were lifted. Then the Medpor framework was fixed to the postauncular periosteum at proper level. Lastly the postauricular facial flap was lifted and was used to cover the framework strictly. Results We have successfully reconstructed 8 cases with this method since 1998. Exposed framework was found in two cases and it was cured after repair. Other cases were satisfactory in appearance. Conclusion Medpor could be a safe and reliable material for auricle reconstruction and with a satisfactory appearance.
