Ameloblastoma previously known as adamantinoma is a histologically benign, locally invasive odontogenic neoplasm of epithelial origin which is derived from the odontogenic ectoderm. It was first described by Cusack in 1827. However, the first detailed description of this lesion was given by Falkson in 1879. The term ‘ameloblastoma’ was coined by Churchill in 1933. Ameloblastoma is an odontogenic tumor representing 1% of all tumors of the jaw, with 80% to 85% occurring in the mandible and 15% to 20% in the maxilla. In the maxilla, 47% of ameloblastomas have been reported in the molar region, 15% in the maxillary antrum and floor of the nose, 9% in the premolar region, 9% in the canine and incisor region and 2% in the palate. Maxillary ameloblastoma is most commonly associated with painless swelling, loosening of teeth, nasal airway obstruction, malocclusion, periodontal diseases and ulceration. The proximity of maxilla to the orbit, skull base and intracranial contents contributes to the high morbidity and mortality rate associated with them.
