Abstract
BACKGROUND: Osteoradionecrosis may develop on the residual mandible or reconstructed fibula because of inadequate soft tissue coverage and compromised tissue perfusion post mandibular reconstruction, and radiation. This study was to investigate the incidence of osteoradionecrosis following class III mandibular defect reconstructions with an OPAC flap versus a fibula OSC flap. METHODS: A retrospective review of a consecutive series of mandibular reconstructions between 1999 and 2010 was performed. Mandibular defects and corresponding flap types were analyzed with emphasis on outcome, complications, and rates of osteoradionecrosis among the two subgroups. RESULTS: A total of 121 fibula flaps were performed, consisting of 53 OPAC and 68 fibula OSC flaps. Complications trended higher for OPAC flaps in partial and total flap loss rates as well as venous congestion when compared with the OSC flap cohort. The OPAC group had statistically significant lower rates of osteoradionecrosis and plate exposure than the OSC group (P = 0.04). CONCLUSION: The OPAC flap may be preferable to fibula OSC flap in mandibular reconstruction given its lower rates of osteoradionecrosis and plate exposure. This flap type may be the flap of choice for class III defects where additional vascularized tissue may be critical for addressing significant soft tissue deficiency. J. Surg. Oncol. 2016;114:399-404.
