Abstract
A 35-year-old female presented an intraoral swelling in the right posterior region of the mandible, which was asymptomatic, with two years of evolution. She presented an anatomopathological report with a previous diagnosis of ameloblastoma, but she was unable complete the proposed treatment due to the COVID-19 pandemic. Clinical examination revealed a granulomatous lesion in the right retromolar region, extending to the vestibular mucosa of elements 46 and 47, together with,bone expansion. A facial tomography showed an expansive, cystic, multilocular lesion, with erosion of the adjacent cortical bone in the right body, angle, and mandibular ramus, measuring approximately 4.6 × 2.2 × 3.7 cm. The patient underwent partial resection of the right posterior mandible with immediate reconstruction of a microvascularized fibular graft and fixation with a reconstruction plate. In the postoperative period, the patient evolved with satisfactory mandibular contour, good mouth opening, and preserved masticatory function.
