A Stafne bone defect is a static bone depression in the mandible that is commonly observed in cortical bone near the mandibular angle. We herein present a rare case in which static bone depressions attached to the three major salivary glands were observed on panoramic radiography and computed tomography (CT). The three static bone depressions in the mandible were visualized on a panoramic radiograph and CT as oval radiolucent masses in a 68-year-old man. The CT numbers in the bone depressions ranged from 10 to 50 HU, and they were close to those of the respective salivary glands. Based on the CT numbers, the areas in the bone depressions were determined to be a normal parotid gland, sublingual gland, and submandibular gland. The patient underwent a follow-up examination and did not request further consultation.
斯塔尔内骨缺损是下颌骨中的一种静态骨凹陷，常见于下颌角附近的皮质骨。我们在此报告一例罕见病例，该病例在全景X线片和计算机断层扫描（CT）上观察到与三大唾液腺相连的静态骨凹陷。在一名68岁男性的全景X线片和CT上，下颌骨的三处静态骨凹陷显示为椭圆形的透光肿块。骨凹陷处的CT值范围为10至50 HU，与相应唾液腺的CT值相近。根据CT值，确定骨凹陷处的区域分别为正常的腮腺、舌下腺和下颌下腺。患者接受了随访检查，未要求进一步会诊。
