Here we report a case of inferior alveolar nerve (IAN), which had variability in its formation. IAN was formed by dual roots, which were branching out from the posterior division of mandibular nerve. The observed roots were forming a loop around the pterygoid part of arteria maxillaris (MA). One of the roots was superficial to the MA and the other was deep to it. It is believed that this type of morphological variation in the formation of IAN can have clinial implications, which include compression by adjacent structures and nerve entrapment. The knowledge of this variation is important to anaesthesiologists and dentists, while administering local anaesthesia. This is also enlightening to the maxillofacial surgeons, neurologists and radiologists.
在此，我们报告一例下牙槽神经（IAN）形成存在变异的病例。IAN由双根组成，这两根从下颌神经后支分出。观察到的根在下颌动脉（MA）翼肌部周围形成一个环。其中一根位于MA浅面，另一根位于其深面。据信IAN形成过程中的这种形态变异可能具有临床意义，包括受到相邻结构的压迫和神经卡压。了解这种变异对于麻醉医生和牙医在进行局部麻醉时很重要。这对颌面外科医生、神经科医生和放射科医生也有启发意义。
