在 3 名接受脑室/腰椎-腹膜分流手术的患者中研究了颅内流体压力 (ICP) 变化对耳蜗流体压力的影响。进行这些手术是为了缓解因ICP异常升高而引起的问题。使用测量鼓膜位移的非侵入性技术在手术前后间接测量外淋巴压力。事实证明，这项技术极其灵敏，并揭示了 ICP 变化引起的耳蜗流体压力的变化。结果强调需要在 ICP 异常的情况下考虑听力学测量。这些发现具有重要意义，因为听力学技术可用于简单且非侵入性的ICP变化连续监测，甚至可以帮助许多神经系统患者的鉴别诊断。
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.
