A. Torus mandibularis
The 6 patients with torus mandibularis (TM ) were 3 men and 3 women. On visual inspection their TM appeared as multi-lobulated masses on the inner aspect of bicuspid and premolar regions, with almost symmetrical extent on both sides. They measured 3-4 cm long, up to 1.5 cm thick, and covered by intact gingival mucosa. CT demonstrated the TM as lobulated exophytic masses of dense cortical hyperostosis, located bilaterally above the mylohyoid line (Figures 1 and 2).
