Two well demarcated ovoid radiolucent lesions (right, 3.9×1.5 cm and left, 2.9×1.1 cm) were found incidentally in the anterior mandible of a 44-year-old female patient on her panoramic dental X-ray (). The patient did not show any symptom of radiolucencies. The radiological findings were interpreted as radicular cysts. Two fragments of tissue from the cavities were submitted for histological diagnosis. The biopsied tissue fragments showed normal salivary gland tissue with mixed serous and mucinous cells. These findings were otherwise unremarkable, except for the small amount of lymphoid cell infiltration that was discovered (). The clinical, radiological, and pathological findings were consistent with Stafne bone cavity.
A 76-year-old at death male Caucasian cadaveric head (fresh-frozen) was dissected. During routine dissection of the head, the mandible was dissected, and the soft tissues of the mandible were removed. After the mandible was separated from the head, a large bony defect was found on the lingual surface of the right mandible, which was located 25.2 mm anterior to the angle of the mandible and 3.3 mm superior to the inferior border of the mandible. The shape and size of the bony defect was oval and 10.8×6.0 mm, respectively (, ). The bony defect had a smooth surface and did not show any pathological condition. Therefore, it was determined to be an SBC. The SBC had continuity with the right mylohyoid groove. The depth of the SBC and width of the mandible at the SBC was 4.15 mm, 3.14 mm, respectively. The SBC was not observed on the left side.
