    Abstract:
    BACKGROUND: In ear reconstruction, the difficulty lies in reestablishing the ear's bionic form with adequate skin coverage and an appropriate framework. Skin expansion and a porous polyethylene (i.e., Medpor) framework are often used for ear reconstruction. However, a long-term review of the combined application of the expanded skin and Medpor framework has not been reported. This article reviews ear reconstruction combining these two factors over the past 20 years in the authors' center to summarize the surgical technique and analyze the postoperative results and complications. METHODS: A retrospective review was performed that included all patients who underwent ear reconstruction with expanded skin and Medpor framework in the authors' center between 1998 and 2018. RESULTS: A total of 68 patients with microtia who were admitted to the authors' center for surgical ear reconstruction were included, and 70 ears were reconstructed. Fifty-seven of the patients (83.82 percent) felt satisfied with their reconstructed ear, five patients (7.35 percent) were not satisfied with the reconstructed ear, and six patients (8.82 percent) had the frameworks removed. Fifteen patients (22.06 percent) developed complications, including framework exposure (13.24 percent), infection (4.41 percent), scar hypertrophy (4.41 percent), and hematoma (2.94 percent). CONCLUSIONS: Framework exposure limits the combined application of expanded skin flap and Medpor framework when reconstructing the ear without additional fascial interposition. Using a temporoparietal fascia or postauricular fascia flap during the operation is effective to decrease the exposure rate; however, this complication cannot be completely avoided. Using postauricular fascia and skin graft may lead to scar hypertrophy; thus, these techniques should be used with caution. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
