Ameloblastomas of the mandible and maxilla.

PURPOSE OF REVIEW: This review focuses on issues in managing ameloblastomas of the mandible and maxilla. We will refer to current practice in the treatment of ameloblastomas based on the available evidence. RECENT FINDINGS: Recent reviews have been trying to establish natural history, growth patterns and malignant potential. This provides the clinicians and the patients with useful prognostic information. Controversies in management of ameloblastomas in relation to the type, age and site exist. This paper aims to categorize these issues. More recently, the authors have adopted the staged treatment approach as an additional step to ensure margin clearance. SUMMARY: Current evidence favours radical resection to provide better control rates. This applies to maxillary lesions of all ages, and solid mandibular lesions in adults (>18 years) where growth has ceased and the patient has matured enough to withstand the impact of resection and reconstruction. Conservative management is advocated for unicystic lesions with good control rates. In children and adolescents, a conservative approach is recommended. This approach aids to minimize both psychological and the impact on growth. Furthermore, most of the lesions are unicystic and the recurrent lesions have been shown to be much smaller and can be managed promptly within a good healthcare system.
