Benefits of routine maxillectomy and orbital reconstruction with the rectus abdominis free flap.

Maxillary defects lead to functional and cosmetic deficiencies, especially with tumor invasion of the orbit and cribriform plate. Additionally problematic is the near-total palatal resection in patients with poor dentition (ie, not useful for anchoring obturators) and the desire for return of deglutition and useful speech. A series of 12 patients is presented in whom a rectus abdominis free flap was used for reconstruction of the palate, maxilla, and/or orbit. Nine of 12 free flaps were used to reconstruct defects involving the maxilla and orbit; all were successful in restoring hard palate continuity and function without the use of an obturator. The remaining 3 patients underwent successful repair of defects involving the orbit and medial maxilla without complication. Four of those 9 patients with palatal reconstruction augmented their dental rehabilitation with either their existing upper denture plate or the use of a cosmetic appliance anchored to their remaining dentition. Objectively, the rectus abdominis myocutaneous free flap proved to be a reliable and expeditious method of restoring function and acceptable cosmesis. We believe this technique should be routinely considered in the reconstruction of these defects.
