Methods Retrorespectively analysis of clinical information in 31 patients who underwent auricular reconstruction from April 2000 to October 2002. Results All 31 reconstructed auricles were in good condition at two weeks postoperatively. Framework protrusion occurred later in 11 patients. The framework was retained in 8 of these cases after secondary repair, but had to be removed in 3 patients. In 27 patients, the reconstructed auricle was rated as esthetically succesful. Conclusion Medpor framework protrusion is likely to occur when skin tension is high with minimal soft tissue coverage over the framework and can result from impact by strong external force. Despite the concern of protrusion, Medpor frameworks can be used in place of autologous cartilaginous graft in auricular reconstruction.展开更多

Objective: Is to evaluate the benefit of using polypropylene mesh to reconstruct helix framework in partial auricular defects covered with local postauricular skin flap. Method: Eleven patients with partial auricular defect were treated by using polypropylene mesh helix framework which is covered with post auricular flap in a two stage repair;clinical results of the procedure were evaluated. Results: This technique achieved satisfactory results in 9 (81.8%) cases. Early Post operative complications: Hematoma formation in one case, mild infection in two cases, edema in two cases, and Partial overlying skin breakdown in one case with failure of technique. Late Post operative complications: Hypertrophic scar in one case, narrow retroauricular sulcus in one case, hair bearing skin over the auricle in one case. Conclusion: It is a simple technique, with satisfactory clinical results, easily done, even under local anesthesia, with no donor site morbidity of autogenous cartilage harvesting, not costly as other alloplastic substitutes, large series and longer follow up period are needed for better evaluation of this technique.展开更多
