内耳的血液是由脑底-椎动脉系统供应的,与颈动脉系统关系不大。内耳动脉分支后在到达耳蜗和前庭器官之前都要经过扭转或螺旋状行走(Twited Course 或 Coiling)。由于螺旋状行走的血管在外观上呈丝球状,所以也称之为“丝球体”。内耳动脉的这种形态学特点在消除动脉搏动而产生的杂音和维持血流稳定方面具有重要作用。但是内耳小动脉的这种极度弯曲和血流速度的缓慢,也比较容易发生各种微循环的障碍。 The blood in the inner ear is supplied by the brain-vertebral artery system and has little to do with the carotid system. The branches of the inner ear are either twisted or coiled after reaching the cochlear and vestibular organs. Because of the helical walking blood vessels in the appearance of a spherical, so it is also called “silk ball.” This morphological characteristic of the inner ear artery plays an important role in removing noise generated by arterial pulsation and in maintaining blood flow stability. However, this extreme curvature of the inner ear artery and slow blood flow, but also more prone to various microcirculation obstacles.
