To present a case of bilateral mandibular accessory canals and foramina observed on CT and review the relevant literature.
Based on the literature, accessory canals and foramina are prevalent in the posterior mandible and the area of the symphysis and more frequently on the internal than the external surface of the mandible. Bilateral symmetry is common. Variations exist in size and number. Occurrence may change with age and racial origin. Nerves, neurovascular bundles, arterioles and venules have been found to occupy the accessory canals and foramina. No gender differences have been described.
CT has advantages over two-dimensional radiography in identification of anatomical variations in the mandible.
呈现一例在CT上观察到的双侧下颌骨副管和副孔病例，并回顾相关文献。
根据文献，副管和副孔在下颌骨后部以及联合处区域较为常见，且在下颌骨内表面比外表面更常见。双侧对称性很常见。其大小和数量存在变异。发生率可能随年龄和种族起源而变化。已发现神经、神经血管束、小动脉和小静脉占据副管和副孔。未描述有性别差异。
在识别下颌骨的解剖变异方面，CT比二维放射成像具有优势。
