Application of osteomucoperiosteal flap in large unicystic ameloblastoma to promote early bone healing: An alternative to primary bone grafting

Abstract

Background:The unicystic variety of ameloblastoma is reported to be significantly less prone to recurrence in young patients than its conventional counterpart, and therefore can be treated conservatively. This paper describes a technique of using an osteoperiosteal flap to allow complete enucleation of a unicystic ameloblastoma. The technique maintains the continuity of the mandible and restores full thickness as well as strength of the mandible to promote early healing. It also maintains blood supply and proper facial contour so that esthetics is unimpaired.Materials and Methods:We describe two cases of unicystic ameloblastoma in which we used an osteoperiosteal flap. This flap was then infractured at the lower border to obliterate the dead space.Results:The sequential radiographs demonstrate early incorporation of the graft and complete filling of the defect by 3 months. At 5 years of follow-up in our first case, complete healing of bone was observed.Conclusions:We believe that these procedures can be the treatment of choice in such cases, especially with larger lesions, as these rapidly restore the patient's facial contour to normal as well as reduce the healing time.
