Abstract

Osteoma is a benign tumor consisting of mature bone tissue. The predilection sites include the skull and jaw bone. We report the case of a 37-year-old male diagnosed with peripheral osteoma of the mandibular angle. The osteoma enlarged by approximately three times during long-term follow-up. The patient visited a physician with the chief complaint of common cold symptoms at the beginning of August 2003. After palpation in the submandibular region, the patient was advised to visit a dentist. Since a radiograph showed radiopacity in the right mandibular angle region, he was referred to our department for further evaluation. Although the tumor was 13 x 10 x 15 mm and had a volume of 2.3 cm3 based on a CT taken in 2003, it had enlarged to 41 x 31 x 37 mm and a volume of 34.6 cm3 based on that in 2016. The osteoma was removed using an extraoral technique under general anesthesia. No relapse was noted over the following 13 months. Shika Igaku (J Osaka Odontol Soc) 2025; Sep; 88(2): 92-100.
