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.
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.
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.
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.
分析右侧与左侧长期单侧耳聋（SSD）对声源定位（SSL）的影响，探讨SSD患者干预治疗的必要性，并从SSL角度分析长期单侧人工耳蜗植入（UCI）的治疗效果。
本研究纳入25例SSD患者、11例UCI患者和30例听力正常（NH）受试者。通过获取他们SSL测试的平均均方根（RMS）误差值来测试其SSL能力。
结果显示，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，SSD-R组和UCI组之间无显著差异。
双侧耳聋患者选择单侧治疗时，右侧人工耳蜗植入在SSL方面可能更有益，这意味着长期SSD患者的中枢听觉皮层根据其耳聋发生的侧别受到不同影响。
