Abstract

Purpose

To analyze the effect of right versus left long-term single-sided deafness (SSD) on sound source localization (SSL), discuss the necessity of intervention and treatment for SSD patients, and analyze the therapeutic effect of long-term unilateral cochlear implantation (UCI) from the perspective of SSL.

Methods

This study included 25 patients with SSD, 11 patients with UCI, and 30 participants with normal hearing (NH). Their SSL ability was tested by obtaining their average root mean square (RMS) error values of SSL test.

Results

The results showed that the RMS error value of SSD, UCI and NH groups were 52.26 ± 20.25°, 69.84 ± 12.14° and 4.27 ± 2.66°, respectively. The ability of SSL was better in the SSD-L group than that in the SSD-R group, and no significant difference existed in the SSD-R and the UCI group.

Conclusion

When bilateral deafness patients select unilateral treatment, right-side cochlear implantation may be more beneficial in terms of SSL, which means that the central auditory cortex in long-term SSD patients is affected differently based on which side their deafness occurs.

左右长期单侧耳聋对声源定位的影响。

目的：分析右、左长期单侧耳聋（SSD）对声源定位（SSL）的影响，探讨对SSD患者进行干预和治疗的必要性，并从SSL的角度分析长期单侧耳蜗植入术（UCI）的治疗效果。方法：本研究纳入25例SSD患者，11例UCI患者和30例听力正常（NH）患者。通过获得其SSL测试的均方根误差值来测试其SSL能力。结果：SSD组、UCI组和NH组的RMS误差值分别为52.26±20.25°、69.84±12.14°和4.27±2.66°。SSD-L组的SSL能力优于SSD-R组，而SSD-R组与UCI组无显著差异。结论：当双侧耳聋患者选择单侧治疗时，右侧人工耳蜗植入可能对侧耳道更有利，这意味着长期耳聋患者的中枢听觉皮层因侧耳耳聋的不同而受到不同的影响。

期刊介绍： Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
