Reconstruction of Partial Auricular Defects by Polypropylene Mesh Helix Framework

Abstract

Background: Current techniques in partial auricular reconstruction can utilize an autologous or alloplastic framework covered by a variety of soft tissue envelopes. 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.
