ACR Codes: 2.1
Palate tori are bony outgrowths (exostoses) seen in the oral cavity that typically arise from the hard palate or inner maxilla/mandible. When arising from the mandible, they are referenced "torus mandibularis." They vary in size (most < 2cm) and shape (flat-broad based, "spindle" shaped with ridges, nodular, or lobular) and are commonly seen by dental professionals and/or head-neck imagers. They are often found in young adults, and they can increase in size over time. There is no known malignant potential.
While tori are usually clinically insignificant, mucosal ulcers may form over tori (presumably from repeated trauma), and hence surgical resection can be performed.
