Abstract

Sensorineural hearing loss (SNHL) is known to be associated with lesions at various sites, including outer hair cell (OHC) and inner hair cell (IHC) injury, as well as auditory dyssynchrony or vestibulocochlear nerve tumors. Therefore, it is important to establish the differential diagnosis of SNHL, which however is particularly challenging in patients with unilateral SNHL. The test battery approach is effective for accurate diagnosis in such cases. In this report, we discuss the usefulness of the test battery approach to accurately detect the site of the lesion in a patient with unilateral hearing loss. A 14-year-9-month-old adolescent who observed decreased hearing sensitivity in the left ear accompanied by difficulty with understanding speech at a distance was diagnosed with unilateral hearing loss in the left ear. In this report, we describe a rare and diagnostically challenging case of unilateral SNHL in a patient with normal OHC function and selective injury to IHCs, which was diagnosed using a test battery approach.

选择性单侧内毛细胞损伤1例报告。

众所周知，感觉神经性听力损失（SNHL）与不同部位的损伤有关，包括外毛细胞（OHC）和内毛细胞（IHC）损伤，以及听觉不同步或前庭耳蜗神经肿瘤。因此，建立SNHL的鉴别诊断是很重要的，然而这在单侧SNHL患者中尤其具有挑战性。在这种情况下，测试电池方法对于准确诊断是有效的。在本报告中，我们讨论了测试电池方法在单侧听力损失患者中准确检测病变部位的有用性。一名14岁至9个月大的青少年观察到左耳听力敏感度下降，并难以理解远处的言语，被诊断为左耳单侧听力损失。在本报告中，我们描述了一例罕见且具有诊断挑战性的单侧SNHL病例，该患者的OHC功能正常，IHC选择性损伤，该病例是使用测试组方法诊断的。

期刊介绍： Journal of Audiology and Otology (JAO) (formerly known as Korean Journal of Audiology) aims to publish the most advanced findings for all aspects of the auditory and vestibular system and diseases of the ear using state-of-the-art techniques and analyses. The journal covers recent trends related to the topics of audiology, otology, and neurotology conducted by professionals, with the goal of providing better possible treatment to people of all ages, from infants to the elderly, who suffer from auditory and/or vestibular disorders and thus, improving their quality of life. This journal encourages the submission of review papers about current professional issues, research papers presenting a scientific base and clinical application, and case papers with unique reports or clinical trials. We also invite letters to the editor and papers related to the manufacture and distribution of medical devices. This journal provides integrated views from otologists, audiologists, and other healthcare practitioners, offering readers high quality scientific and clinical information. This peer-reviewed and open access journal has been the official journal of the Korean Audiological Society since 1997 and of both the Korean Audiological Society and the Korean Otological Society since 2017. It is published in English four times a year in January, April, July, and October.
