    Abstract:
    The Medpor implant is another choice for a new auricular framework besides autogenous costal cartilage. However, its relatively frequent exposure and less-matching skin coverage discourage surgeons from using it. In this article, we present a new two-flap method, a combination of the temporoparietal fascial flap and the expanded skin flap, for wrapping the Medpor implant in microtia reconstruction. A staged surgical procedure was performed, including soft tissue expansion in the mastoid region, soft tissue expander removal, expanded skin flap and temporoparietal fascial flap formation, Medpor framework implantation, and the combined two-flap envelopment. Conventional lobule transposition and tragus reconstruction were accomplished for selected patients. In this study, a total of 22 microtias were reconstructed consecutively using this method. Eighteen patients were followed since the first surgery. The postoperative follow-up time ranged from 3 to 12 months. The draped soft tissue covering was thin enough to show the reconstructed ear with excellent, subtle contour when edema gradually vanished 3-6 months postoperatively. The new ear had a stable shape, and its skin color and texture matched the normal surrounding skin very well. No exposure or extrusion of the framework was observed in the series. The Medpor implant enveloped by both a temporoparietal fascial flap and an expanded cutaneous flap appears to be a promising alternative for the auricular framework in microtia reconstruction. Because of the wrapping tissues, auricular construction using a Medpor implant can be a safe, steady, and easily acceptable choice for both microtia patients and their physicians.
