小儿面神经血供的应用解剖学研究

Applied anatomical study on blood supply of facial nerve in childhood

目的探讨小儿面神经的动脉来源及分布。方法10具小儿尸体头颈部标本经双侧颈总动脉插管,加压注入红色乳胶,观察面神经的动脉来源及分布。结果面神经颅外段营养动脉来源于茎乳动脉、颞浅动脉面神经支、面横动脉、颈外动脉上面神经支、颈外动脉下面神经支、面动脉后面神经支和面动脉前面神经支。面神经颅内段营养动脉来源于茎乳动脉、脑膜中动脉的岩支、迷路动脉。结论为面神经血供来源及分布提供形态学基础,避免手术时损伤。

Objective To explore the arterial origin and the distribution of the facial nerve. Methods Red latex was injected into the arteries of 10 head specimens in childhood by both common carotid artery catheterization. The arterial origin and distribution of the facial nerve were observed. Results The nutrient arteries of the extracranial segment of the facial nerve originated from stylomastoid artery, the facial nervous branch of superficial temporal artery, transverse facial artery, superior and inferior facial nervous branches of external carotid artery and the posterior and anterior facial nervous branches of facial artery. The nutrient arteries of the segment of the facial nerve originated from petrous branch of middle meningeal artery, stylomastoid artery, labyrinthine artery. .Conclusion The blood supply of the facial nerve can provide anatomic basis for avoiding injury of the nutrient arteries of the facial nerve during operation
