Recurrent ameloblastoma of the maxillo-facial region. Clinical features and treatment.

21 recurrent cases of ameloblastoma in the maxillofacial region in Nigerian subjects are described. These had a typical age, sex and site distribution and characteristic clinical features. Extension of the disease into the cranial vault was seen in one individual but no metastasis was detected at presentation and follow-up review. The effective surgical treatment was en bloc excision with preservation of the lower border of the mandible or radical resection often including adherent soft tissues and skin. Follow-up data were recorded and all the patients were free from the disease for 6 months to 6 years.
