Immediate Reconstruction of Extruded Alloplastic Nasal Implants With Irradiated Homograft Costal Cartilage†
Presented at the Annual Meeting of the Triological Society, Palm Desert, CA, May 15, 2001.
Abstract
Objective To describe a novel surgical protocol for the management of patients presenting with extruded nasal implants.
Study Design Retrospective chart review.
Methods Analysis of consecutive patients presenting with extruded nasal implants from 1986 to 2000. Patients were selected from a large database of revision rhinoplasty cases. Inclusion criteria were: 1) at least one previous rhinoplasty procedure, 2) an extruded nasal implant that was documented preoperatively, 3) immediate reconstruction that was carried out with irradiated homograft costal cartilage (IHCC), and 4) at least 1 year of follow-up recorded, including standard postoperative rhinoplasty photographs. A total of 18 patients met the inclusion criteria and form the basis of this study. Data gathered from the charts included date of surgery, last date of follow-up, location of implant extrusion, alloplastic material, specific use of IHCC for reconstruction, percent of clinical IHCC resorption at last follow-up, and presence of warping of the IHCC.
Results All 18 patients were satisfied with the cosmetic outcomes of their nasal reconstructions. The most common extruded alloplast was Silastic, followed by Gore-Tex (W.L. Gore & Associates, Inc., Flagstaff, AZ). There were no cases of extrusion or infection of the IHCC implant subsequent to immediate reconstruction of the extruded alloplast. Clinical resorption of the IHCC was minimal, with a mean follow-up of 26 months. Only one patient had a complication, warpage, resulting in removal of the IHCC. In that patient, the IHCC still had carving markings on the implant after 2 years in vivo.
Conclusions In this series of patients, a novel surgical protocol was used. The extruded implant was removed and immediate reconstruction with irradiated rib cartilage was done. All patients were evaluated for postoperative infection, graft extrusion, and satisfaction with cosmetic result. There was one major complication in this series of 18 patients, warping of the IHCC, which necessitated removal and replacement. This approach appears to be a reasonable method for reconstruction of extruded nasal alloplasts.
