The mental nerve is a sensory nerve which traverses through mental foramen to innervate the lower lip, chin skin and the mandibular labial gingiva. Interestingly, it's variant such as the accessory mental foramen (AMF) was described as an unusual finding in the recent literature. Hereby, we reported a patient who was operated to treat the mandibular bisphosphonate-related osteonecrosis of the jaw (BRONJ) lesion. Intraoperatively, an accessory mental foramen was detected posterior to the main foramen and nerve, on the right side of the mandible. This case report highlighted the necessity for proper radiological and clinical evaluation of mental foramina in order to avoid nerve injury and postoperative paresthesia. The review of the literature and the clinical findings were also discussed in this article.
颏神经是一条感觉神经，它穿过颏孔以支配下唇、颏部皮肤及下颌唇侧牙龈。有趣的是，其变异情况，如副颏孔（AMF），在最近的文献中被描述为一种不寻常的发现。在此，我们报告了一名接受手术治疗下颌双膦酸盐相关颌骨坏死（BRONJ）病变的患者。术中，在右侧下颌骨主孔和神经后方检测到一个副颏孔。本病例报告强调了对颏孔进行适当的影像学和临床评估的必要性，以避免神经损伤和术后感觉异常。本文还讨论了文献回顾及临床发现。
