氧的供给对维持内耳功能十分重要。根据解剖和生化的观点,螺旋器的氧供给主要依靠鼓阶外淋巴,外淋巴的氧供给主要来自于内耳血管,其次是通过耳蜗导水管由脑脊液供给,还有一种可能性是由鼓室通过圆窗膜向鼓阶外淋巴供氧。作者为7只体重在250～400克之间、鼓膜正常的豚鼠作实验。在耳蜗基底转的骨壁上钻孔,插入氧敏感电极到距圆窗膜0.5mm的鼓阶外淋巴中,参照电极放在颞肌中,用极谱技术测定鼓阶外淋巴的氧张力。将加压的空气导八鼓室,2.3±0.2分钟后测得外淋巴的氧张力由原
The supply of oxygen is important to maintain the inner ear function. According to the anatomical and biochemical point of view, the helical oxygen supply depends mainly on the extra-apod lymph, the outer lymph supply of oxygen mainly from the inner ear vessels, followed by the cochlear aqueduct supplied by the cerebrospinal fluid, there is a possibility that the tympanic circle Window film to the outer drum lymph oxygen supply. The authors were 7 guinea pigs weighing 250 to 400 grams with normal tympanic membrane. Drill holes in the cochlear basal turn bone wall, insert the oxygen-sensitive electrode into the outer drum of the tympanum 0.5mm away from the round window membrane, place the reference electrode in the temporal muscle, and measure the oxygen tension of the outer drum’s lymph by polarography. The pressurized air guide eight tympanic room, 2.3 ± 0.2 minutes after the measured outer lymph oxygen tension from the original
