The effects of changes in intracranial fluid pressure (ICP) on cochlear fluid pressure have been studied in 3 patients who underwent ventriculo/lumbar-peritoneal shunt operations. The operations were performed in order to alleviate problems caused by an abnormally raised ICP. Indirect measurements of perilymphatic pressure were made before and after surgery using a non-invasive technique which measures tympanic membrane displacement. This technique proved extremely sensitive and revealed changes in cochlear fluid pressure brought about by changes in the ICP. The results emphasise the need to consider audiological measurements in the context of ICP abnormalities. These findings have important implications in that an audiological technique may be used for the simple and non-invasive serial monitoring of changes in ICP and may even assist differential diagnosis in a number of neurological patients.
对3例接受脑室/腰-腹腔分流手术的患者，研究了颅内压（ICP）变化对耳蜗内液体压力的影响。进行这些手术是为了缓解因ICP异常升高引起的问题。术前和术后使用一种测量鼓膜位移的非侵入性技术对外淋巴压力进行了间接测量。该技术被证明极其灵敏，揭示了由ICP变化引起的耳蜗内液体压力的变化。结果强调了在ICP异常的情况下需要考虑听力测量。这些发现具有重要意义，因为一种听力技术可用于简单且非侵入性地连续监测ICP的变化，甚至可能有助于一些神经科患者的鉴别诊断。
