A stained or colored perilymph would be a valuable tool to otologists for the detection of a perilymph fistula. We studied the effect of intravenously injected fluorescein on the inner ear in seven cats. Still and video photography was used to clearly document our findings. Intravenously injected fluorescein appeared within the soft tissue in less than 1 minute and stayed there for at least 3 1/2 hours. Fluorescence around the round window niche resulted from soft tissue (mucosal) fluorescence and extravasation of interstitial fluid (transudate). No fluorescence of perilymph was detected. Because of this, we do not believe intravenously injected fluorescein is useful in the detection of perilymph fistula. Intrathecal injection caused quick and intense staining of labyrinthine fluid.
染色或带色的外淋巴对于耳科医生检测外淋巴瘘来说是一种很有价值的工具。我们研究了静脉注射荧光素对7只猫内耳的影响。使用静态和视频摄影来清晰记录我们的发现。静脉注射的荧光素在不到1分钟内出现在软组织中,并在那里停留至少3个半小时。圆窗龛周围的荧光是由软组织(黏膜)荧光和间质液(漏出液)外渗引起的。未检测到外淋巴有荧光。因此,我们认为静脉注射荧光素在检测外淋巴瘘方面并无用处。鞘内注射导致迷路液迅速且强烈地染色。
