Abstract

Objective To assess the efficacy of a modified facial translocation technique in preventing translocated facial bone graft from necrosis, which is the most common complication of facial translocation.

Study Design Prospective.

Methods A lateral nasal flap was preserved and transposed to resurface the inner surface of the translocated facial bone graft in a facial translocation approach to skull base tumors in 35 patients including 24 patients with radiation therapy between July 1998 and December 2000.

Results Only one patient had bone graft necrosis. Thirty-four (97%) of 35 patients had intact mucosa covering the inner surface of the translocated facial bone graft. The outcome was not affected by preoperative or postoperative radiation therapy.

Conclusions A modified facial translocation technique using a lateral nasal flap to resurface the inner defect of the translocated facial bone graft significantly improved the viability of the translocated facial bone graft, especially in patients who underwent radiation therapy. The use of a lateral nasal flap does not interfere with the detection of early local recurrence.
