Abstract: Objective To evaluate the features of auricle reconstruction by Medpor framework plantation, and to explore the reasons for framework exposure. Methods 31 cases of microtia, who had been treated by using the Medpor framework in Beijing Tongren Hospital during April 2000 to October 2002, were studied retrospectively. Results 31 cases were cured without any complications after one stage and all discharged after two weeks of the operation. The follow-up result showed that 11 cases had the framework exposed partially, among which 8 cases were treated locally, the other 3 cases' frameworks taken out. The auricle shape of 27 cases had good cosmetic result. Conclusion The main reason of framework exposure includ the skin tension?thin skin flap or the effect of external force. In spite of the high rate of framework exposure, Medpor framework is still a good substitute for the rib cartilage framework.
