Mandibular traumatic peripheral osteoma: a case report

An osteoma is a slow-growing, benign lesion comprising mature bone tissue. Osteomas rarely occur in maxillary bones, with the exception of the maxillary sinuses. Various possible etiologies have been proposed, including congenital anomalies, chronic inflammation, muscular activity, embryogenetic changes, and trauma. Here we present a case of an osteoma of the buccal plate of the mandible at the site where a sports-related traumatic injury occurred 15 years earlier. Both conventional and 3-dimensional x-ray examinations were used for diagnosis and preoperative evaluation of the possible involvement of the adjacent anatomic structures. The lesion was treated surgically without complications and the patient made a complete recovery. Histologic tests confirmed the preoperative diagnosis. A review of the international literature is also presented.
