Advantages of the scapular system in mandibular reconstruction.

Abstract

Fibula free flaps (FFF) are often considered the first choice for mandibular reconstruction, but scapular system free flaps (SFF) have increased in popularity due to versatility, donor site advantages, and patient factors. Retrospective chart review of patients undergoing mandibulectomy with FFF or SFF reconstruction from 2016 to 2021. Hundred and seventy-six patients (FFF n = 145, SFF n = 31) underwent the aforementioned procedures. Mean FFF operative time was 9.47 h versus 9.88 for SFF (p = 0.40). Two-flap reconstructions required 12.65 h versus 10.09 for SFF with soft tissue (p = 0.002). Donor site complications were identified in 65.6% of FFF with skin grafting. These findings suggest that SFF requires similar operative time and results in reduced donor site morbidity as compared to FFF. Supine, concurrent harvesting of SFF allows for single-flap harvest with significantly shorter operative time. SFF could be considered a primary option for mandible reconstruction for complex defects and in select patients.
