当科における顎骨外骨症の臨床的検討

Abstract

Two hundred forty cases of exostosis in the oral cavity were clinically investigated. Patients were 57 males and 183 females and mostly in their 4 th to 6 th decades of age. Torus palatinus was observed in 143 patients and torus mandibularis in 126 patients. Symptoms such as pain and abnormal sensation were found in 38% of patients. Torus palatinus were mostly 15-25 mm in size and morphologically flat and spindle types. Three fourths of torus mandibularis were bilaterally observed and multiple type was found more frequently than single type. Twenty-five percents of torus palatinus were accompanied by torus mandibularis. Surgical excision was performed in 25 cases, mostly in cases with symptoms.
