Although various theories such as trauma and infection have been proposed, it is difficult to establish the pathogenesis of osteoma. Osteomas may be detected with routine radiographic examination or the tumors may enlarge and cause symptoms. Osteomas most frequently occur in the frontal and ethmoid sinuses, and are rare in the maxillary sinus. Case report: In the present study, we report a case of an 18-year-old woman with a maxillary sinus osteoma. Radiographically, the tumor was characterized as a radiopaque, well-delimited lesion in the periapical region of teeth 27 and 28 that had positive sensitivity test. After computed tomographic scanning and complete removal of the tumor, the histopathological diagnosis was osteoma. After 1 year of follow-up, the patient shows no signs of recurrence. © 2011 Springer-Verlag.
