Segmental resection for the excision of two multicystic ameloblastoma

Objectives. The purpose of this study was addressed at the understanding and management in the ameloblastoma treatment, performing a segmental surgical resection. Ameloblastoma represents nearly 1% of all neoplasm located  Annali di Stomatologia 2014; Suppl. 3 to n. 2: 1-41 15 in the oral cavity. In 80% of cases it could be found in the mandible, of these lesions 70% are located in the molar re- gion or the ascending ramus, 20% in the premolar region and 10% in the anterior part. It is considered as a benign neoplasm with slow growing-pattern and locally aggressive behaviour. Methods. On the basis of clinicoradiological findings, ameloblastoma is divided into 3 groups: solid or multicystic, unicystic and peripheral. The solid ameloblastoma represents nearly 86% of all lesions; it has a tendency to be more aggressive than the other types with a higher incidence of recurrence. The high tax of recurrence represents a dan- ger for patients. The prognosis for ameloblastoma is more dependent on the method of surgical treatment rather the histologic type of tumour. Resection with some safe margin is considered the best primary method for treating sol- id/multicystic ameloblastomas because it results in a lower recurrence rates compared with a conservative approach. Results. In this study we report the treatment of two multicystic ameloblastomas located in the anterior part of the mandible with a surgical segmental resection. Challenges, in this two cases, were related to extension and position of the lesions, which required a careful isolation of the mental foramen. Conclusions. After a follow-up period of two years no recurrence have been detected. These two cases support the evidence of literature, that considers the surgical resection as the best approach to reduce recurrence in patients with multicystic ameloblastoma.
