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).
