Stafne bone cavity (SBC) is a bone defect which appears unilaterally round or oval shaped radiolucent area with well-defined border. The most common location of the defect is the mandibular molar area at the lingual side of the mandible, below the mandibular canal. Additionally other rarer variants of SBC, anterior lingual, buccal aspect of ascending ramus, and lingual aspect of ascending ramus are also reported. In this paper, a rare case of posterior and anterior variant of double SBCs with buccal cortical bone perforation was presented. An 83-year-old male patient was referred to our clinic for a routine dental examination. Panoramic examination presented two well-defined radiolucent areas. One was located at the right posterior region of the mandible, below the inferior alveolar canal and the second in the region of right canine-premolar area, anterior of the mental foramen. Cone beam computed tomography also confirmed the defects. Magnetic resonance imaging of patient showed that posterior variant was filled with part of submandibular gland and anterior variant was filled with part of sublingual gland. The diagnosis was made as double SBCs and the patient was informed about the lesions.
Stafne 骨腔（SBC）是一种单侧圆形或椭圆形的透亮区域，边界清晰。缺损最常见的位置是下颌磨牙区下颌舌侧，下颌管下方。此外，还报道了 SBC 的其他罕见变异型，如前舌侧、升支颊侧和升支舌侧。本文报道了一例罕见的双侧 SBC 后前变异型伴颊侧皮质骨穿孔的病例。一名 83 岁男性患者因常规牙科检查就诊于我院。全景片显示两个界限清晰的透亮区。一个位于下颌骨右侧后区，在下颌牙槽管下方，另一个位于右侧尖牙-前磨牙区，颏孔前方。锥形束 CT 也证实了这些缺损。患者的磁共振成像显示，后变异型内填充了部分下颌下腺，前变异型内填充了部分舌下腺。诊断为双侧 SBC，并告知患者病变情况。
