The palatal island flap technique (the vascular pedicled mucoperiosteal island flap) has been reported to be useful for the reconstruction of the defect in the oral region. The purpose of this study is to investigate the procedure and the wound healing of the donor site, and the postoperative sensorial recuperation of donor and recipient sites. 10 cases reconstructed with palatal island flap were examined. The largest defect was 40×40 mm and the smallest one was 5×10 mm. To donor sites, skin graft, fibrinoplastic agents, lyophilized porcine skin, or atelocollagen were applied, and reepithelizing terms were measured. Postoperative sensorial recuperation of donor and recipient sites appeared perfectly in two years. In conclusion, this technique was found to be useful for the reconstruction of oral mucosa, because of technical ease and least disturbance.
