The lingual nerve (LN) is a branch of the mandibular division of the trigeminal nerve, and its injury is one of the major complications during oral surgery. This study aims to investigate the anatomy of the LN in the lower third molar area. Twenty sides from ten fresh-frozen adult cadaveric Caucasian heads were examined to measure the diameter of the LN. The mean diameter of the LN was 2.20±0.37 mm (range, 1.61-2.95 mm). There were no statistically significant differences in the measurements between sexes, sides, or tooth status (dentulous or edentulous). Understanding the anatomical features of the LN is essential for performing any surgical procedure in the oral region.
舌神经（LN）是三叉神经下颌支的一个分支，其损伤是口腔外科手术中的主要并发症之一。本研究旨在调查下颌第三磨牙区域舌神经的解剖结构。对来自10个新鲜冷冻的成年白种人尸体头部的20侧进行检查，以测量舌神经的直径。舌神经的平均直径为2.20±0.37毫米（范围为1.61 - 2.95毫米）。性别、左右侧或牙齿状态（有牙或无牙）之间的测量结果无统计学显著差异。了解舌神经的解剖特征对于在口腔区域进行任何外科手术至关重要。
