A review of 156 Odontogenic Tumours in Calabar; Nigeria

Background: Odontogenic tumours occur in our environment and because of late treatment; cause considerable disabilities. Objective: To review cases of odontogenic tumours in our centre in order to obtain a baseline data and subsequently compare the results with that obtained elsewhere. Patients and methods: Using hospital case files and register; we carried out a 15-year retrospective study of odontogenic tumours at the Dental and Maxillofacial Clinic; University of Calabar Teaching Hospital; Nigeria. The data documented include age; gender; duration of lesion; type of tumour; socio-economic class; type of surgery; and complaints during follow-up reviews. Results: Majority of the patients (n=49; 31.4) were in the third decade of life. There were 85 (54.5) males and 71 (45.5) females; giving male to female ratio of 1.2:1. There was a significant association between the type of odontogenic tumour and the age of occurrence (p=0.000). The longer the duration of symptoms before presentation; the larger the tumours (p=0.000). The benign odontogenic tumours were 151 (96.8); ameloblastoma (n=74; 47.4) being the commonest. Jaw resection (54.5) was the predominant treatment. Majority (58.0) of the complications following treatment were Facial deformity; malocclusion and impaired mastication. Conclusion: Majority of the patients was in the lower socio-economic class; presented late for treatment and a few with aesthetic and functional impairment returned for secondary surgery. The intervention of agencies of government and non-governmental organizations is required to assist these patients if we are to accomplish the core healthcare system values in our environment

Ameloblastic Fibroma: Presentation and Management at two Nigerian Tertiary Hospitals

Background: Ameloblastic fibroma (AMF) is a relatively uncommon neoplasm of odontogenic origin. Aim: To appraise the prevalence; presentation and management of AMF in two major tertiary hospitals in Nigeria. Methods: Histopathology records of the Departments of Oral and Maxillofacial Surgery of the two hospitals were reviewed and histologically confirmed cases of AMF seen over a 23- year period were selected. The case records of the selected cases were retrieved and the presentation and management of the disease were analyzed and discussed. Results: Seventeen cases of histologically confirmed AMF were seen over the period under study. The age range was 10 - 63 years and mean age of occurrence was 27.1 + 16 years; there was no sex predilection but the mandible was the commonest site of occurrence. Most cases were treated by conservative excision but some cases had more extensive resection. No tumour recurrence was observed over an average follow up period of 2 years. Conclusion: AMF with a prevalence of 3.1in this study; remains a rare variety of odontogenic tumour and is amenable to conservative surgical excision preptrrrase. Large lesions may warrant more radical resection but recurrence is generally rare
