- Abstract
Mandibular bone depression, also known as Stafne bone cavity, is defined as a bone depression filled mainly with salivary gland tissue. Parotid gland bone defects are infrequently observed. We report the case of a 52-yearold male patient who underwent radiographic examinations due to temporomandibular joint dysfunction, and a radiolucent area was detected in the mandibular ramus, with a provisional diagnosis of traumatic bone cyst or parotid mandibular bone defect. The patient was then referred for magnetic resonance imaging, which demonstrated a hyperintense area eroding the mandibular ramus, which corresponded to glandular tissue. Although the defect was a benign lesion, radiolucencies in the mandibular ramus lead to concerns among professionals, because their radiographic features can resemble various intrabony neoplastic lesions, such as giant cell tumors or benign tumors of the parotid gland.
