How to Do a Split Mentalis Muscle Flap for Central Marginal Mandibular Defects.

Tumors of the central mandible requiring marginal mandibulectomy and floor of mouth resection require reconstruction for cosmetic and functional purposes. Numerous reconstructive techniques have been described for small-moderate sized defects of the central mandible/anterior floor of mouth. Robust local flaps have been well described; however second stage procedures are required for pedicle division. The split mentalis muscle flap is a simple, quick and low morbidity option for central mandibular defects and has been demonstrated effectively with the use of a split skin graft. We provide a modification of the split mentalis muscle flap without the morbidity associated with a split skin graft and its utility to support a prosthesis following surgery and radiotherapy.
