Dual free flap transfer using forearm flap for mandibular reconstruction.

To reconstruct a composite mandibular defect, we have simultaneously transferred a vascularized bone graft or osteocutaneous flap together with a forearm flap. The radial forearm flap, being thin, pliable, and having a long vascular stalk, served as mucosal lining and/or an interpositional flap acting as a vascular bridge. Between 1982 and 1989, we used this procedure in 17 patients with a mandibular defect or deformity which developed following treatment of oral cancer. Our clinical experience has demonstrated that this dual free tissue transfer has many advantages. It is useful for obtaining a good alveolar ridge in patients with a composite mandibular defect. It is applicable in cases where only a single pair of recipient vessels are present and may be useful when the recipient vessels are positioned some distance from the defect.
