Reconstruction of an inferior orbital rim and cheek defect with a pedicled osteomyocutaneous submental flap.

BACKGROUND The purpose of this study was to present the feasibility of reconstructing an inferior orbital rim and cheek defect with a pedicled osteomyocutaneous submental flap. METHOD A 77-year-old women with a right nasosinusal adenoid cystic carcinoma invading soft tissues and skin of the cheek, the inferior rim of the orbit, the hard palate, and the middle turbinate is presented. A right radical maxillectomy with preservation of the eye was performed. A pedicled osteomyocutaneous submental island flap was used to reconstruct the defect. An inferior marginal mandibular section was incorporated with the flap and used to reconstruct the inferior orbital rim. RESULTS Satisfactory cosmetic and functional results were reached by reconstructing the inferior rim of the orbit and the cheek skin using this flap. CONCLUSION This is the first case report of an osteomyocutaneous submental flap for reconstruction of an inferior orbital rim defect.
