Concurrence of Torus Mandibularis with Multiple Buccal Exostoses

symptoms may occur in the oral cavity and cause problems when the patient is fitted with dentures. In such cases, the tubercles shoud be removed by surgery [1]. Buccal exostoses are multiple bony nodules that occur less frequently than tori. A statistical study on the incidence of tori has been published, but cases of the treatment and prognosis of patients with a con­ currence of tori and multiple buccal exostosis are rarer [3]. In addition, most bony exostoses are found incidentally during dental care by a dentist because they are generally small and do not have symptoms, so plastic surgeons rarely experience them. Thus, we present the clinical features of symptom­ atic tori mandibularis and multiple buccal exostoses based on our experience and treatment and survey some rare cases in the literature from the field of plastic surgery. A 50­year­old man had a slowly growing intraoral mass that had appeared about 5 years earlier from the bone that arose from the alveolar process of the maxilla and mouth floor of the mandible. Though there was no discomfort in the early period, the tubercles were gradually becoming larger, and it held food remnants after meals and produced an intraoral foreign body sensation. In his family history, his younger sister had experienced a mandibular protu­ berance that was similar to the patient’s lesion, but she had not visited the hospital for diagnosis or treatment. In the physical examination, multiple buccal exostoses approximately 0.5 to 1.0 cm in size were observed in the alveolar portions of the maxilla and both sides of the lingual aspect of the mandible, while TM were observed, about 2.5 cm×1 cm in size, on the canine to premolar region. These bony tubercles were nodular in shape and had a thin mucous mem­ brane, but ulcers or other lesions were not observed (Fig. 1).
