Donor site morbidity of the prelaminated fasciomucosal and fasciocutaneous radial forearm flap: a comparative study

Abstract 

In order to reconstruct intraoral lining defects after radical tumor resection, mucosal prelamination of the fascia of the distal radial forearm flap was performed in ten patients. By this method a physiologic reconstruction with mucus-producing tissue could be achieved. Preservation of skin and subcutaneous tissue enabled primary closure of the donor site. The exposed median nerve and flexor tendons could be covered by well-vascularized tissue with, hopefully, less donor site morbidity. To investigate this, eight prelamination patients were compared to five patients in whom conventional fasciocutaneous distal radial forearm flaps were harvested. Follow-up was 6–25 months (mean 12.8 months). All patients with prelaminated forearm flaps revealed excellent functional and cosmetic results. Restricted hand function and a poor cosmetic result were found in 40% of the fasciocutaneous flap patients. Subjective cold intolerance could be objectified using thermography, but could not be confirmed, using rheography and photoplethysmography.
