Pediatric Mandibular Reconstruction With Free Serratus Anterior-Rib Composite Flap: A Case Report

Reconstruction of children's mandibles after mandibular resection for benign or malignant tumors is challenging. Microvascular flap reconstruction is a common treatment option for restoring mandibular continuity after the resection of oral cavity neoplasms.We presented 2 cases of childhood mandibular reconstruction after tumor wide excision and segmental mandibulectomy, one for malignant cancer and one for benign ossifying fibroma, with serratus-rib composite free flap. All 2 patients had a favorable facial profile, functional outcome, and dental occlusion at the last follow-up. The development of children's mandible and donor site needs to be considered compared with adult's mandibular reconstruction. Given its reliability and utility, this flap can be an alternative for pediatric mandibular reconstruction compared with the free fibular flap and other candidates.
