Mucosal Prelamination of a Radial Forearm Flap for Intraoral Reconstruction

ABSTRACT

For reconstruction of intraoral soft-tissue defects after radical resection of squamous-cell carcinomas, the microvascular jejunal patch has been a reconstructive graft option of first choice. In addition to other advantages, these jejunal grafts are able to produce mucus. In cases in which the use of jejunal grafts is contraindicated, the fasciocutaneous radial forearm flap has enlarged the spectrum of reconstructive options. A disadvantage is that mucus production will be absent, because mucosal and lining reconstruction is performed with tissue lacking mucus-providing qualities. The authors successfully prelaminated a distal radial forearm flap with buccal mucosa in five patients. Mucosal prelamination of the distal radial forearm flap enables a physiologic reconstruction with resultant mucus production, in combination with the provision of thin, pliable, and resistant flaps. The technique lowers donor-site morbidity because of the preservation of skin and subcutaneous tissue. Reconstruction with fasciomucosal, osteomyomucosal, and myomucosal flaps by this method seems feasible.
