Lingual mandibular bone depression, also known as the Stafne bone cavity, commonly presents as an asymptomatic unilocular cyst-like radiolucency located below the mandibular canal. Surgical exploration of this lesion is relatively rare in the literature. A 49-year-old male was admitted to the hospital for a space-occupying lesion located in the right mandibular angle region and was performed surgical exploration. The content of the lesion was excised and prepared for histologic investigation, which revealed fibrous connective tissue, adhering muscle and nervous tissue with no evidence of epithelium tissue. Thus, the lesion was diagnosed as lingual mandibular bone depression. Of the various theories of the etiology of lingual mandibular bone depression, the most popular "glandular theory" seemed to be inapplicable in the present case. Providing misleading information in this case, B-mode ultrasonography was proved to be of little help in diagnosing this lesion.
下颌舌骨骨凹陷，亦称 Stafne 骨腔，通常表现为下颌管下方无任何症状的单房囊性透光区。该病变的手术探查在文献中相对少见。一名 49 岁男性因右侧下颌角区占位性病变就诊，接受了手术探查。切除病变内容物并准备进行组织学检查，结果显示纤维结缔组织、附着的肌肉和神经组织，无上皮组织证据。因此，诊断为下颌舌骨骨凹陷。在各种下颌舌骨骨凹陷病因理论中，最流行的“腺体理论”似乎不适用于本病例。在本病例中，B 型超声提供了误导性信息，对诊断该病变帮助不大。
