The inferior alveolar nerve (IAN) is a sensitive branch of the mandibular nerve innervating the lower lip, the chin, the buccal mucosa and the teeths. Lesions of the IAN are reported to occur in the 64,4% of maxillo-facial procedures, leading to anesthesia, hypoestesia and/or neurogenic discomfort. An extensive segment of the nerve can be moreover removed during mandibular resection for benign or malignant pathologies. Nervous grafts can be used in these cases to restore the nerve continuity. In order to optimize the procedure and to allow a concomitant mandibular osseous reconstruction, the Authors identified several standardized steps. The technique described allows to perform confortable and safe nervous anastomoses and to reduce the risk of damage and tension during the flap insetting phases.
下牙槽神经（IAN）是下颌神经的一个敏感分支，支配下唇、颏部、颊黏膜和牙齿。据报道，IAN 的损伤在颌面外科手术中发生率为 64.4%，导致麻醉、感觉减退和/或神经源性不适。在良性或恶性病变的下颌骨切除术中，神经的广泛节段可以被切除。在这些情况下，可以使用神经移植物来恢复神经连续性。为了优化手术并允许同期进行下颌骨骨重建，作者确定了几个标准化步骤。所描述的技术允许进行舒适和安全的神经吻合，并降低在皮瓣插入阶段损伤和张力的风险。
