根据Axelsson的研究,鼓阶的回流静脉于耳蜗基底转末端注入圆窗静脉,圆窗膜的血供也为圆窗静脉的分支所引流(1968)。内耳除圆窗膜外都为骨质所包裹,也就是只有通过圆窗膜才能在不必去除耳蜗骨质的条件下观察内耳的血流情况。这就存在着通过对圆窗血流的观察而可以为临床提供有关内耳血流情况的可能性。作者们以18只豚鼠进行此项研究。动物用氨脲腹膜腔内注射麻醉。外侧进路切开右侧耳泡,去除鼓膜。圆窗以超高压水银灯的适当滤光束照明,使用显微镜进行圆窗血流的观察,并以每秒12～30张的速度拍摄其动态照相。
According to Axelsson’s study, the dorsal veins of the scala tympanum are injected into the round window veins at the cochlear basal end-turn, and the blood supply of the round window membrane is also drained by the branches of round veins (1968). In addition to the inner ear round window membrane are surrounded by bone, that is, only through the round window membrane in the absence of cochlear bone conditions to observe the inner ear blood flow. This leads to the possibility of providing clinically relevant blood flow in the inner ear through observation of the round window blood flow. The authors conducted the study with 18 guinea pigs. Animals were anesthetized with carbamide intraperitoneally. The lateral approach incises the right ear bud and removes the tympanic membrane. The round window is illuminated with the appropriate filter beam of an extra-high pressure mercury vapor lamp and the round window blood flow is observed using a microscope and its motion picture is taken at 12 to 30 frames per second.
