The Use of Coronoid Process as a Free Graft for Condylar Reconstruction in a Patient With Condylar Osteoma: A Condylar Reconstruction Technical Note (Technical Strategy).

Osteoma is a rare, asymptomatic, and slowly growing benign tumor of bone. Upon reviewing the literature, only 21 cases were previously reported in the mandibular condyle. A 19-year-old male patient presented to the Department of Oral and Maxillofacial Surgery of Ain Shams University complaining of hypomobility and facial asymmetry involving the lower jaw. He stated that he was involved in a road traffic accident (RTA) and sustained a traumatic injury to the head a few years ago. Upon examination, it was noticed that the chin deviated to the right side with some discomfort during function. Computed tomography scans revealed the presence of a hyperdense mass medial to the right condylar pole. Condylectomy was carried out using a preauricular approach. A diagnosis of osteoma was confirmed histopathologically. The defect was reconstructed using the coronoid process as an autogenous-free graft.
