Microvascular free flap reconstruction versus palatal obturation for maxillectomy defects.
BACKGROUND
Palatal obturators and microvascular free flaps are both used to treat patients with maxillectomy defects, however, the optimal technique remains controversial.


METHODS
A retrospective analysis of 113 patients undergoing maxillectomy for cancer was performed. Seventy-three patients received an obturator and 40 patients were reconstructed with a free flap.


RESULTS
Speech intelligibility and postoperative diet were comparable between the obturator and free flap groups, except in cases of extensive (>50%) palatal defects, where free flap reconstruction was superior in both aspects (p = .019 and p = .043, respectively). The average time for presenting with a local recurrence in advanced cancer involving the palate was comparable in both groups (p = .33).


CONCLUSIONS
Moderate-sized maxillectomy defects involving the palate can be successfully treated with either an obturator or free flap reconstruction. Extensive defects have a better functional outcome with free flaps. Evidence does not suggest that free flap reconstructions delay diagnosis of local recurrences.
