Abstract
PURPOSE: This study was undertaken to investigate the morphologic changes in the forearm flap in the oral environment. PATIENTS AND METHODS: Histologic evaluation of biopsy specimens from 20 forearm flaps was done 1 to 75 months after intraoral reconstruction after treatment of cancer. Hematoxylin and eosin and Azan were used to stain the deparaffinized sections. RESULTS: The clinical features of the grafted flap seemed to depend on the time since the operation. The cornified layer of the epidermis of the flaps showed thinning histologically. CONCLUSION: After 11 months of exposure to an intraoral environment, "mucosalization" of the forearm flap is evident.
