C. Torus maxillaris
Torus maxillaris (TMAX ) had developed in 3 patients, one man and 2 women. These tori appeared bilaterally as prominent and lobulated masses arising from the medial aspects of the upper jaw. In contrast to TM, these were located more posteriorly along the molar regions. These tori were very firm on palpation and consisted of marked cortical hyperostosis on CT sections. One patient also had a coexisting TP as illustrated by CT and intraoral images (Figure 5).
