The iliac crest and the radial forearm flap in vascularized oromandibular reconstruction

Sixty cases (59 patients) of oromandibular reconstruction using vascularized iliac crests were compared with 13 in which radial osteocutaneous flaps were used. These patients were reviewed from the standpoint of cosmetic results and function as well as their operative and postoperative courses. In both groups, the results were generally good. However, revisionary surgery was more frequent in those receiving the iliac crest. This group also had a higher incidence of intraoral wound breakdown and bone exposure. Nevertheless, the sheer size of the iliac crest made it ideal for massive oromandibular defects, just as its natural curvature lent itself to precise replication of the mandible in bone-only reconstructions. Its bulk proved a major obstacle in small composite defects. The radial forearm flap carried thin, pliable, well-vascularized skin that was superior to groin skin for oral lining. Bone gaps of up to 9 cm could be handled with ease, thus making it complementary to the iliac crest over the wide spectrum of mandibular reconstruction.
