Management of Large Mandibular Ameloblastoma Crossing Midline: Reconstructed by Bilateral Iliac Crest Graft: A Rare Entity.

ABSTRACT

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenic neoplasm. It’s incidence approximately 1% of all oral tumors and 18% of all odontogenic tumors. More than 80% of cases of ameloblastoma occur in mandible. The ameloblastoma occurs in three variants solid or multicystic, unicystic, and peripheral. A painless expansion of the jaws is the most common clinical presentation. The correct diagnosis can be easily made with the help of plain X-rays and tissue biopsy. The standard management of ameloblastoma is marginal resection but sometimes a large tumor requires complete resection of affected part. Untreated tumors may lead to tremendous facial disfigurement, a severe malocclusion and pathological fractures of the jaw. Here we present a case of a young man with the chief complaint of facial asymmetry. The orthopantomogram of the patient was showing a multilocular radiolucency with Buccal and lingual cortical expansion. A diagnosis was made on the basis of the biopsy as multicystic ameloblastoma, and resection of the mandible was carried out. The mandibular primary reconstruction was done with avascular bilateral iliac crest bone graft. Long term prognosis showed satisfactory healing and good facial esthetics.
