Maxillary Reconstruction With a Rib-attached Free Latissimus Dorsi Muscle Flap.

Abstract

In defect reconstruction after maxillary tumor resection, filling the dead space created by resection and reconstruction of surrounding areas are crucial for good cosmetic outcomes. Although various procedures have been described in the literature, most are complex and require advanced surgical skills. Therefore, in this study, the authors aimed to identify a simple procedure for successful reconstruction with minimal bone fixation. Three patients who underwent total maxillectomy and reconstruction using the rib-attached free latissimus dorsi flap at Keio University Hospital between 2012 and 2014 were included and followed up with for a minimum of 5 years. After total maxillectomy, the authors used a free latissimus dorsi flap with a portion of the rib to fill the dead space and reconstructed the orbit, nasal cavity, and oral cavity.The authors performed a rigid reconstruction of the zygomatic ridge using only 2-point plate fixations of the ribs at the outer orbit and anterior nasal spine. Patients were followed up for ≥5 years, and the flap successfully survived in all cases. There was an issue with rib fixation in 1 case; however, all patients were highly satisfied with the procedure's cosmetic results.
