The periosteal-cutaneous chimeric medial femoral condyle free flap for subtotal ear reconstruction: A case report.

When costal graft is contraindicated or refused by the patient, autologous total/subtotal auricular reconstruction represent a real challenge as limited surgical options has been described. Aim of present report is to offer a novel possible autologous reconstruction of the ear frame using a chimeric free medial femoral condyle (MFC) flap. We present a case of a 29 years old patient who had total loss of the upper 2/3 of the right ear after bombing in Somalia and secondary infected condritis (considered a relative contraindication for costal cartilage graft). The MFC flap was harvested with a chimeric skin paddle (7 × 5 cm), a thin sheet of femoral cortex (6.5 × 8 cm) was used as basal ear frame, while part of the contralateral concha was trimmed as support for the helix, with the periosteal component of the flap wrapping around the whole framework. The chimeric skin paddle assured the retroauricular skin coverage, while the anterior part of the construct was covered by a thinned dermal flap. Postoperative course was uneventful. A defatting procedure of the posterior skin paddle was performed at 2 months post-op. At 6 months post-op, the patient was satisfied with the result, could wear glasses and was socially integrated. This new application of the free chimeric MFC flap, despite being not the primary choice for ear reconstruction, guaranteed satisfactory results in terms of ear shape and infection prevention and may be considered when ordinary cartilage rib reconstruction is refused, contraindicated, or failed.
