Abstract

The currently available evaluation methods for determining appropriate treatment strategies in patients with asymptomatic inner ear dysfunction are insufficient. Recently, we demonstrated the efficacy of 100-Hz sound stimulation for treating vestibular dysfunction in Meniere’s disease. This case report presents the utility of 100-Hz sound stimulation as a new method for evaluating cases with asymptomatic vestibular dysfunction and their potential for recovery with early medical intervention. We evaluated the change in cervical vestibular-evoked myogenic potential (cVEMP) amplitude before and after sound stimulation (75 dB at a frequency of 100 Hz for 5 to 10 min) in two female patients with endolymphatic hydrops (EH), comparing the change based on the presence of EH. One patient presented with hearing difficulty and the other with otalgia, and neither had hearing loss and vestibular symptoms. As a result, cVEMP amplitudes in ears without EH showed no changes after the stimulation. Conversely, cVEMP amplitudes showed significant increases in ears with vestibular EH compared with the values before stimulation. Application of a 100-Hz sound stimulus might be a new method for evaluating asymptomatic vestibular dysfunction associated with EH, and for providing information about the potential for recovery from the dysfunction, facilitating early medical intervention.

声音刺激治疗无症状前庭功能障碍的新方法。

目前可用的评估方法，以确定适当的治疗策略，对无症状内耳功能障碍的患者是不够的。最近，我们证实了100赫兹声音刺激治疗梅尼埃病前庭功能障碍的疗效。本病例报告介绍了100赫兹声音刺激作为一种评估无症状前庭功能障碍病例的新方法，以及他们通过早期医疗干预恢复的潜力。我们评估了两名女性内淋巴水肿（EH）患者在声音刺激（75 dB，频率为100 Hz，持续5至10分钟）前后颈前庭诱发肌电位（cemp）振幅的变化，并比较了EH存在的变化。一名患者表现为听力困难，另一名患者表现为耳痛，两名患者均无听力损失和前庭症状。结果表明，刺激后无脑出血的耳cemp振幅无明显变化。相反，与刺激前相比，前庭EH耳朵的cemp振幅显着增加。应用100hz声音刺激可能是评估与EH相关的无症状前庭功能障碍的新方法，并提供有关功能障碍恢复潜力的信息，促进早期医疗干预。

期刊介绍： The international journal Auris Nasus Larynx provides the opportunity for rapid, carefully reviewed publications concerning the fundamental and clinical aspects of otorhinolaryngology and related fields. This includes otology, neurotology, bronchoesophagology, laryngology, rhinology, allergology, head and neck medicine and oncologic surgery, maxillofacial and plastic surgery, audiology, speech science. Original papers, short communications and original case reports can be submitted. Reviews on recent developments are invited regularly and Letters to the Editor commenting on papers or any aspect of Auris Nasus Larynx are welcomed. Founded in 1973 and previously published by the Society for Promotion of International Otorhinolaryngology, the journal is now the official English-language journal of the Oto-Rhino-Laryngological Society of Japan, Inc. The aim of its new international Editorial Board is to make Auris Nasus Larynx an international forum for high quality research and clinical sciences.
