Abstract：
Inner ear decompression sickness (IEDCS) is an uncommon diving-related injury affecting the vestibulocochlear system, with symptoms typically including vertigo, tinnitus, and hearing loss, either in isolation or combination. Classically associated with deep, mixed-gas diving, more recent case series have shown that IEDCS is indeed possible after seemingly innocuous recreational dives, and there has been one previous report of IEDCS following routine hyperbaric chamber operations. The presence of right-to-left shunt (RLS), dehydration, and increases in intrathoracic pressure have been identified as risk factors for IEDCS, and previous studies have shown a predominance of vestibular rather than cochlear symptoms, with a preference for lateralization to the right side. Most importantly, rapid identification and initiation of recompression treatment are critical to preventing long-term or permanent inner ear deficits. This case of a U.S. Navy (USN) diver with previously unidentified RLS reemphasizes the potential for IEDCS following uncomplicated diving and recompression chamber operations - only the second reported instance of the latter.
摘要：
内耳减压病（IEDCS）是一种罕见的潜水相关损伤，会影响前庭耳蜗系统，症状通常包括眩晕，耳鸣,听力损失,无论是孤立还是组合。经典地与深层联系在一起，混合气体潜水,最近的一系列案例表明，在看似无害的娱乐性潜水之后，IEDCS确实是可能的，在常规高压舱手术后，有一份关于IEDCS的报告。存在右向左分流(RLS)，脱水,胸内压升高已被确定为IEDCS的危险因素，以前的研究表明，前庭症状占主导地位，而不是耳蜗症状，偏向右侧。最重要的是,快速识别和开始再加压治疗对于预防长期或永久性内耳缺陷至关重要.美国海军（USN）潜水员先前身份不明的RLS案例再次强调了IEDCS在简单的潜水和减压室操作后的潜力-仅是后者的第二个报告实例。
