Patients with single-sided deafness (SSD) are limited by their asymmetric hearing in various areas of everyday life.
The aim of this investigation was to perform an age-correlated comparison of the hearing threshold of the better ear of SSD patients with a normal-hearing (NH) reference cohort. In addition, the potential influence of etiology, duration of deafness, and cochlear implantation (CI) of the poorer ear on the peripheral hearing ability of the better ear was investigated.
In a multicenter study, the mean bone conduction hearing threshold of the better ear of 413 adult SSD patients was compared with that of an NH cohort drawn from ISO 7029:2017 for the frequencies 0.5, 1, 2, and 4 kHz.
SSD patients showed significantly poorer hearing in the better ear compared to the age-correlated group of NH subjects. CI, duration of deafness, and etiology had no significant effect on the hearing ability of the better ear.
The origin of the poorer hearing of the better-hearing ear of SSD patients compared to an age-correlated NH cohort is still unclear. It is most likely a combination of different anatomical, immunological, etiological, and microcirculatory causes, which lead to poorer hearing of the better-hearing ear in SSD patients.
单侧耳聋（SSD）患者在日常生活的各个方面都受到其不对称听力的限制。
本研究旨在对SSD患者较好耳的听力阈值与正常听力（NH）参考队列进行年龄相关性比较。此外，还研究了病因、耳聋持续时间以及较差耳的人工耳蜗植入（CI）对较好耳外周听力能力的潜在影响。
在一项多中心研究中，将413例成年SSD患者较好耳的平均骨导听力阈值与从ISO 7029:2017中抽取的NH队列在0.5、1、2和4kHz频率下的平均骨导听力阈值进行比较。
与年龄匹配的NH组相比，SSD患者较好耳的听力明显较差。CI、耳聋持续时间和病因对较好耳的听力能力没有显著影响。
与年龄匹配的NH队列相比，SSD患者较好听力耳听力较差的原因尚不清楚。很可能是不同的解剖学、免疫学、病因学和微循环原因共同作用，导致SSD患者较好听力耳的听力较差。
