面神经颊支与腮腺导管及面动脉位置关系的应用解剖学研究OA
Applied anatomical study on the positional relationships among buccal branch of facial nerve,parotid duct and facial artery
目的 通过观察并测量面神经颊支、腮腺导管、面动脉的相关数据,分析三者之间的位置关系,以避免术中结扎面动脉时误伤面神经颊支及腮腺导管.方法 对40例成人头颈部标本进行解剖,观察面神经颊支与腮腺导管的关系、面动脉的走行及位置关系、面神经颊支与周围血管网的关系,游标卡尺测量相关径线.结果 面神经颊支分为上颊支和下颊支,与腮腺导管之间没有直接吻合或连通纤维,上颊支常较粗,位置较恒定,与腮腺导管平行;下颊支位置不恒定,在口角平面或其稍上方走行;上颊支距腮腺导管(10.76±5.54)mm,下颊支距腮腺导管(6.84±4.06)mm.面动脉主干走行位置较为固定,且若出现面动脉分支缺失的情况,面动脉其他分支会延伸替代缺失的分支动脉;面动脉主干直径(2.34±0.83)mm,其分支与上颌动脉的颊动脉分支吻合形成腮腺区及颊区血管网.面神经颊支周围存在血管网,多为面动脉、颞浅动脉的细小分支.结论 面神经颊支与腮腺导管、面动脉存在较恒定的解剖毗邻关系,术中结扎面动脉时以腮腺导管为标志定位面神经颊支,可很大程度上避免误伤面神经颊支及腮腺导管.
Objective By observing and measuring the relevant data of the buccal branch of the facial nerve,the parotid duct and the facial artery,the positional relationship among the three was analyzed to avoid accidental injury to the buccal branch of the facial nerve and the parotid duct when ligaturing the facial artery during the operation.Methods Forty adult head and neck specimens were dissected to observe the relationship between the buccal branch of the facial nerve and the parotid duct,the course and positional relationship of the facial artery,and the relationship between the buccal branch of the facial nerve and the peripheral vascular network.The relevant diameters were measured with a vernier caliper.Results The buccal branch of the facial nerve was divided into the superior buccal branch and the inferior buccal branch,and there was no direct anastomosis or connecting fiber between the buccal branch of the facial nerve and the parotid duct.The superior buccal branch was relatively thick,and it has a relatively constant position,which was parallel to the parotid duct.The position of the inferior buccal branch was not constant and it ran on or slightly above the plane of angulus oris.The superior buccal branch was located(10.76±5.54)mm from the parotid duct,while the inferior buccal branch was positioned(6.84±4.06)mm away from the parotid duct.The course of the main trunk of the facial artery was relatively fixed.Moreover,if the branch of the facial artery was missing,other branches of the facial artery would extend to replace the missing branch artery.The main trunk of the facial artery had a diameter of(2.34±0.83)mm,and its branches formed anastomoses with the buccal branch of the maxillary artery,creating a vascular network in the parotid and buccal regions.There was a vascular network around the buccal branch of the facial nerve,which was mostly small branches of the facial artery and the superficial temporal artery.Conclusion The buccal branch of the facial nerve exhibits a consistent anatomic relationship with the parotid duct and the facial artery.During the ligation of the facial artery,the parotid duct can serve as a landmark to accurately locate the buccal branch of the facial nerve,thereby significantly reducing the risk of inadvertent injury to the buccal branch of the facial nerve and the parotid duct.
