Abstract
Since 1996 we have performed mucosal prelamination of the distal radial forearm flap for functional reconstruction of defects of the intraoral lining. This study was undertaken to demonstrate that the prelaminated fasciomucosal radial forearm flap can provide physiological oropharyngeal reconstruction with mucus-producing tissue, while avoiding the donor-site complications of the fasciocutaneous radial forearm flap. We examined the donor hand at least 6 months postoperatively in 20 patients after using a prelaminated fasciomucosal radial forearm flap and in 15 patients after harvesting a classical fasciocutaneous radial forearm flap. The evaluation of hand function included range of motion, grip power, pinch power, sensibility and vascular analysis in both hands. The patients were asked about cold intolerance, pain and any restrictions in daily life, and the cosmetic appearance of the donor hand was noted. In the prelaminated-flap group (n 20), two patients had decreased wrist extension, and one of these patients also had reduced strength and mild hypaesthesia in the donor hand. In the classical-fasciocutaneous-flap group (n 15), six patients had decreased wrist extension, five patients had reduced strength and four patients had diminished sensibility in the donor hand. Painful neuromas were found only after fasciocutaneous flaps (three cases). Subjective assessment revealed restricted hand function in one patient in the prelaminated-flap group, and in five patients who had undergone fasciocutaneous flap transfer. The results of this study show that using the prelaminated fasciomucosal radial forearm flap minimises the donor-site morbidity. Furthermore, we were able to improve the cosmetic appearance of this very exposed region.
