摘要: 下牙槽神经损伤是下颌阻生第三磨牙拔除常见并发症,下牙槽神经分支通常会增加术中神经损伤的风险。本文报告1例下颌神经管磨牙后管分支伴行附近的阻生齿拔除病例,通过锥形束计算机断层扫描(cone-beam computed tomography, CBCT)并结合相关文献对磨牙后管走行及临床存在风险进行讨论。

Abstract: Inferior alveolar nerve injury is a common complication of mandibular impacted third molar extraction, and the branching of the inferior alveolar nerve usually increases the risk of intraoperative nerve damage. This article reports a case of a mandibular nerve canal with a posterior canal branch located near the impacted tooth. The course and clinical risks are discussed through CBCT combined with relevant literature.

Key words: inferior alveolar nerve, posterior canal of molars, impacted teeth
