Current practice in the management of peripheral ameloblastoma: a structured review

Ameloblastoma is the most common benign, but locally destructive, epithelial odontogenic tumour. Peripheral ameloblastoma may involve soft tissues without invasion or involvement of bone. The aim of this structured review was to evaluate the literature and guide clinical management. Three online databases were searched for relevant studies: Medline, EMBASE, and Ovid Evidence-Based Medicine, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A total of 520 papers were initially identified, and after exclusions were applied, 45 were included. Conservative surgical excision was the treatment of choice. There was no consensus in relation to the extent of the surgical margins required. The management of peripheral ameloblastoma appears to favour conservative excision with narrow margins of normal tissue. Follow up of at least 10 years is recommended to monitor for recurrence.
