ABSTRACT

Background: Ameloblastoma is a benign tumor that originates from odontogenic epithelium. It develops in the region of the jaws but in 80% of cases it is located in the posterior region of the mandible. It has an intraosseous and progressive growth, causing expansion of cortical bone and up to 50% recurrence during the first five years if it is not treated properly. A conservative treatment may prevent esthetic and functional sequelae entailed by more aggressive treatment options for this type of lesions. Objective: We emphasize the importance of a strict clinical and imaging follow up to give the patient the possibility of undergoing conservative treatments for this type of odontogenic tumors. Material and methods: A 22-year-old female patient presented with a mural unicystic ameloblastoma in the region of the right mandibular body and angle. She was initially treated by decompression plus extraction of the associated tooth. Two years later, enucleation and curettage of the lesion was performed. Clinical and imaging follow up of the patient was done two months after surgery. Results: The conservative treatment by marsupialization with subsequent enucleation and curettage resulted in the complete neoformation of the condylar neck, coronoid process, ramus, angle, and mandibular body. Conclusions: Unicystic ameloblastomas can be treated by means of an initial decompression that helps to preserve and regenerate the affected anatomical regions to subsequently perform the enucleation of the lesion and thus prevent the esthetic and functional sequelae of conventional treatment.
