本文在53侧成人头部标本上对舌神经在下颌第三磨牙区的毗邻关系进行了研究。舌神经在第三磨牙后区多为扁圆形,在第三磨牙舌侧多为扁平形,平均横径为1.7mm,舌神经距第三磨牙槽嵴的垂直距离为11.2mm、距第三磨牙远中距离为9.0mm、距牙槽骨舌侧骨板的水平距离为3.0mm、距下颌舌骨肌附着缘的距离为6.2mm。对拔除第三磨牙时,损伤舌神经的解剖学原因进行了探讨并提出防止其损伤的建议。 In this study, 53 adjacent human head specimens of the lingual nerve in the third molar area adjacent to the study. The lingual nerve was mostly oblate in the posterior area of ​​the third molars, mostly flat in the lingual side of the third molars, with an average transverse diameter of 1.7 mm. The vertical distance between the lingual nerve and the third molar ridge was 11.2 mm, Molar distal distance was 9.0mm, the horizontal distance from the alveolar bone plate was 3.0mm, the distance from the mandibular hyoid muscle attachment edge was 6.2mm. Anatomy of the injured lingual nerve during the removal of the third molars was explored and recommendations were made to prevent its damage.
