[Osteomuscular serrato-costal free flap: application to mandibular reconstruction].

The serrato-costal free flap provides a large costal flap vascularized by a digitation of the serratus anterior muscle supplied by the dorsal thoracic artery. The flap is easy and rapid to raise with low morbidity. The repair obtained is functionally very satisfactory, but does not allow insertion of an implant. Six cases are reported. The indications of this technique of mandibular reconstruction are discussed.
