To estimate the Single-sided deafness (SSD) among sensorineural hearing loss (SNHL) in Tertiary Care Rehabilitation Centre. To determine the audiological characteristics, associated and medical problems, and rehabilitative approaches among SSD.
A retrospective study was conducted to report on demographic details, audiological evaluation, and hearing aid management among SSD clients. A total of 11,534 cases of SNHL were reported to the Audiology department at the tertiary care rehabilitative center at Mysuru between January 2014 and December 2017.
A total of 225 were diagnosed as having SSD, accounting for approximately two cases of SSD in a cohort of 100 SNHL cases (225/11,534*100). In addition, males are affected more than females. SSD is found to have more in the right ear than the left ear. Their major complaints were tinnitus and vertigo, apart from reduced hearing sensitivity from the affected ear. In the side of the ear with profound hearing loss among SSD clients showed normal middle ear status with absent acoustic reflexes, otoacoustic emissions, and auditory brainstem response. Only 54 individuals (24%) out of 225 SSD clients underwent a hearing aid trial. Twenty-one (9%) SSD clients purchased a hearing aid, and a minuscule seven (3%) of 225 SSD clients are using a hearing aid. The preference for hearing aid uptake was low because of the experience of vibratory sensation and having near-normal hearing in one ear.
Two cases of SSD were observed among SNHL and they are less likely to get benefits from the hearing aid.
评估三级护理康复中心感音神经性听力损失（SNHL）患者中的单侧耳聋（SSD）情况。确定SSD患者的听力学特征、相关及医学问题以及康复方法。
进行一项回顾性研究，报告SSD患者的人口统计学细节、听力学评估及助听器使用情况。2014年1月至2017年12月期间，共有11534例SNHL病例报告至迈索尔三级护理康复中心的听力学科室。
共诊断出225例SSD患者，在100例SNHL病例中约有2例SSD（225/11534×100）。此外，男性受影响多于女性。SSD在右耳的发生率高于左耳。他们的主要症状除患耳听力敏感度下降外，还有耳鸣和眩晕。在SSD患者中，听力严重损失一侧的中耳状况正常，但声反射、耳声发射和听觉脑干反应消失。225例SSD患者中只有54人（24%）进行了助听器试用。21例（9%）SSD患者购买了助听器，225例SSD患者中仅有7例（3%）使用助听器。由于有振动感体验且单耳听力接近正常，使用助听器的意愿较低。
在SNHL患者中观察到2例SSD患者，他们从助听器中获益的可能性较小。
