Abstract

Odontogenic myxofibroma is a benign odontogenic tumor of mesenchymal tissue that generally originates from the mandible. It is an extremely rare tumor accounting for approximately 2% of all odontogenic tumors. In this report, the authors presented a giant right mandibular mass that extends to the angle of the mandible and displacing the tongue laterally caused significant malocclusion, pain, and impaired oral intake. The tumoral involvement of the mandibula required a partial mandibulectomy with the resection of right mandibular ramus, body, and bilateral parasymphysis. Right mandibular condyle was preserved. The mandibular defect was reconstructed with a fibula free flap. Three-dimensional printed maxillofacial bone model of the patient was used as contour modeling and guide. Histopathologic examination confirmed the diagnosis as odontogenic myxofibroma. The purpose of the report is to present a very rare case of odontogenic myxofibroma and its general characteristics, radiological features, differential diagnosis, surgical management, and the use of three-dimensional printing technology in the field of mandibular reconstruction.
