We analyzed 10 maxillary ameloblastomas clinicostatistically for the past 23 years from 1970 to 1992. The incidence of maxillary ameloblastoma was 6. 5% of all ameloblastomas in the jaw bones. Age at the initial visit was the fifth decade or over in eight patients. Many tumors extended from the anterior or premolar to molar region and 6 cases involved the maxillary antrum. There was no case with an embedded tooth in the tumor. Radiographically, unilocular and multilocular radiolucency was seen in the majority of cases. Histologically, follicular type was seen in six cases, basal cell ameloblastoma in 3, and desmoplastic ameloblastoma in 1. Two cases of follicular type and 1 of basal cell ameloblastoma were malignant ameloblastomas. Recurrence was noted in 2 of the cases; both of these 2 cases were malignant ameloblastomas.
