Free-Flap Reconstruction of the Mandible

Roderick Y Kim et al. Semin Plast Surg. 2019 Feb.

Abstract

Mandible reconstruction has evolved over the years with advances in surgical options and three-dimensional technology. Although nonvascularized bone grafting is still used, vascularized flaps show advantages with immediate reconstruction, the possibility of immediate dental implants, and the ability to reconstruct composite defects of both soft tissue and bone. This article discusses current vascularized techniques for mandible reconstruction. While each reconstructive method has advantages and disadvantages, a defect-based reconstruction focused on full rehabilitation allows surgeons to plan and counsel the patient for the best available reconstruction.

Keywords: complications; free flaps; mandible reconstruction.
