title: Clinical characteristics and presentation of ameloblastomas: an 8-year retrospective study of 240 cases in Eastern Nigeria.
abstract: Our aim was to summarise the clinical characteristics and presentation of ameloblastomas in eastern Nigeria. We organised a retrospective study of 240 patients who presented with ameloblastomas to the Oral and Maxillofacial Surgery units of five specialist hospitals in the eastern states of Nigeria over an eight-year period (2004-2011). We analysed the casenotes, and categorised the cases by site of tumour, age, sex, and time of presentation. There were 117 men (49%) (mean (SD) age 43 (6.2) years) and 123 women (51%) (mean (SD) age 32 (4.7) years), a male:female ratio of 1:1.1. The largest age group was 20-39 years (n=102, 43%), and the most common site was the anterior mandible (n=140, 58%). Most of the patients presented late. Our results show that the most common site of ameloblastomas in Eastern Nigeria is the anterior mandible and that women are affected more than men, which is at variance with the results of most other studies.
