Figure 1. Torus mandibularis (TM) in a 61 year-old man. CT section shows the prominent bilateral exostosis (arrows). Intraoral photograph (inset) demonstrates lobulated subgingival masses on the inner aspect of premolar regions. Figure 2. Torus mandibularis (TM) in a 58 year-old woman, presenting as very extensive osteomas on CT image (arrows), and as lobulated masses protruding medially on intraoral view (inset). She had progressive impairment of speech and mastication due to posterior displacement of the tongue and subsequently required surgical excision of the tori. Figure 3. Torus Maxillaris (TMAX) in a 47 year-old man. CT shows very prominent bilateral exostosis of the molar regions (large black arrows), minimal cortical thickening anteriorly (small arrows) and a coexisting TP (white arrow). Intraoral photograph also demonstrates the same tori (inset). Figure 4. Torus palatinus (TP) in a 72 year-old man. CT and intraoral images demonstrate the torus as a prominent multi-lobulated mass protruding from center of the hard palate (arrow). This torus was removed surgically because of its large size and recurrent ulceration of its mucosa. Figure 5. Torus palatinus (TP) in a 50 year-old woman. CT section shows the lesion as an exostosis of the hard palate. Photograph reveals superficial erosions and inflammation of its mucosal surface (arrows).
