Clinical applicative analysis and comparison of two kinds of auricle reconstruction by Medpor framework and cartilage framework

Objective To observe the application and effect of two kinds of auricle reconstruction and find the idea one.Methods 60 cases of congenital microtia or auricle defection after external injury were divided into 2 groups:Group A(34 cases),cartilage framework was wrapped by the extended auricular area skin;Group B(26 cases),Medpor auricular framework was wrapped by the superficial temporal fascia which was covered by skin graft.Results 6 month to 5 years follow-up showed that there are 2 cases with framework exposure,2 cases with unclear figure,1 case with local defection in group A and 1 case with framework exposure,2 cases with unclear figure,1 case with local defection in group B.The cured auricle's satisfactory rate was 85.3% and 84.6 %(P0.05) respectively in two groups.There was no significant difference in two groups.Conclusions Auricle reconstruction with cartilage framework by stages is comparatively reliable,but if the organic characteristics of the Medpor framework are comprehended totally,auricle reconstruction with Medpor framework is an ideal one.By choosing the proper surgical method and skillfully operating during the surgery,auricle reconstruction with Medpor framework method could reduce the complication to the minimal extent,which means less injury,simple operation,short course of treatment and reliable after-operation effect.
