目的 探讨面神经颅外段的动脉来源及分布。 方法 15例新鲜尸体头颈部标本经双侧颈总动脉插管 ,加压注入红色乳胶或过氯乙烯填充剂 ,观察面神经颅外段的血供来源及分布。 结果 面神经营养动脉来源于耳后动脉的茎乳动脉、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 ,其外径分别为 (0 .8± 0 .2 ) mm、(0 .9± 0 .4 ) mm、(1.9± 0 .3) mm、(1.0± 0 .2 ) mm、(1.1± 0 .4 ) mm、(1.0± 0 .2 ) mm和 (1.1± 0 .6 ) mm。各营养动脉除营养面神经外还发出分支相互吻合 ,构成了丰富的面神经血管网。 结论 了解面神经颅外段动脉血供来源及分布 ,为避免腮腺咬肌区手术损伤面神经营养血管提供了解剖学基础。
Objective To explore the arterial origin and the distribution of the extracranial branches of the facial nerve. Methods Red latex or red chlorinated polyvinyl chloride was injected into the arteries of 15 fresh adult head specimens by both common carotid artery catheterization. The arterial origin and distribution of the extracranial branches of the facial nerve were observed. Results The nutrient arteries of the extracranial branches of the facial nerve originated from stylomastoid artery of the posterior auricular 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 external carotid artery. The outer diameters of them were (0.8±0.2) mm, (0.9±0.4) mm, (1.9±0.3) mm, (1.0±0.2) mm, (1.1±0.4) mm, (1.0±0.2) mm and (1.1±0.6) mm respectively. The sub-branches of the attendant artery of the facial nerve anastomosed each other in addition to supplying their own nerve, and a rich vascular network was formed between the facial nerve and adjacent tissue. Conclusion The study on blood supply of the extracranial segment of the facial nerve can provide anatomic basis for avoiding injury of the nutrient arteries of the facial nerve during operation of the parotidean and masseteric region clinically.
