Tratamento cirúrgico de ameloblastoma com reconstrução mandibular com enxerto de crista ilíaca: relato de caso

Abstract

Ameloblastoma is a benign odontogenic tumor of epithelial origin, with slow growth and asymptomatic. The literature describes three variants of this neoplasm, which differ according to clinical and radiographic aspects, being classified as: solid conventional or multicystic ameloblastoma, unicystic and peripheral or extraosseous. Regarding the treatment, there are divergent currents, in which some authors defend the conservative approach, curettage and enucleation; while others prefer radical conduct, resection with a safety margin. Thus, the aim of this study is to report a case of ameloblastoma with a surgical approach and discuss the therapy adopted, resection with a safety margin, followed by reconstruction with a graft from the iliac crest. We present a 34-year-old male patient, referred to the Stomatology’s Clinic of the College of Dentistry of the Federal University of Uberlândia, due to an image finding in the region of elements 33, 34 and 35 in a panoramic radiograph. An incisional biopsy was performed and the collected material was sent for histopathological analysis, with a conclusive result for ameloblastoma. The treatment approach chosen by the Oral and Maxillofacial Traumatology Surgery team at the UFU Dental Hospital was radical resection with a safety margin. One year after excision of the lesion, an autogenous graft from the iliac crest was performed. The patient is being followed up for forty-one months without recurrence and is awaiting rehabilitation with dental implants. Therefore, the present work has the relevance of demonstrating the success of the therapy adopted in a case of multicystic ameloblastoma.
