TREATMENT OF EXTENSIVE MULTICYSTIC AMELOBLASTOMA IN THE MANDIBLE WITH IMMEDIATE RECONSTRUCTION: CASE REPORT

Abstract

Ameloblastoma is a benign odontogenic tumor of epithelial origin, locally aggressive, with an incidence of 0.5 cases per million. It is more common in the posterior region of the mandible, mainly during the third and fourth decades, with no sex preference. The World Health Organization classifies the tumor in different clinical variants and histologic patterns. A 34-year-old male patient presented a severe symphyseal swelling, with an undetermined evolution period. Tomographic findings revealed a mandibular hypodense, multilocular, poorly delimited image, with cortical destruction, measuring 95 mm in diameter. After the initial diagnosis of ameloblastoma, obtained through incisional biopsy, the lesion was completely resected with safe margins and the mandible was immediate reconstructed with a patient-specific titanium prosthesis. The histologic examination confirmed the previous diagnosis and the negative margins of the surgical specimen. The patient's recovery was uneventful, with no signs of recurrence and satisfactory mandibular function.
