Perilymphatic hypertension is usually related to gushers which occur in the operating room when the stapes footplate is punctured or removed. These patients present defects in the modiolus, or enlarged cochlear aqueducts, which allow easy access of spinal fluid to the perilymphatic space. This syndrome was detected in children and appears to present consistent audiological patterns. They present a mixed hearing loss and in spite of the presence of an air-bone gap the stapedial reflexes are present. These children benefit from the use of hearing aids but show very little insertion gain in the low frequencies when tested with real-ear measurements.
外淋巴高压通常与手术室内镫骨底板被穿刺或移除时出现的“喷射现象”有关。这些患者存在蜗轴缺损或扩大的蜗水管，使得脑脊液易于进入外淋巴间隙。该综合征在儿童中被发现，似乎呈现出一致的听力学模式。他们表现为混合性听力损失，尽管存在气骨导差，但镫骨肌反射存在。这些儿童受益于助听器的使用，但在进行真耳测量时，低频的插入增益非常小。
