To investigate the insertion speed and its impact on electrode insertion characteristics, hearing preservation and clinical vestibular function in a prospective cohort study with a retrospective control group at a tertiary otology/neurotology centre.
Hearing-preserving cochlear implantation using systemic and topical steroids in conjunction with a round-window approach, a complete cochlear coverage electrode and two different electrode insertion speeds [60 mm/min (n = 18) vs. 15 mm/min (n = 22)] was performed.
The insertion speed had a significant impact on various insertion characteristics as well as hearing preservation and vestibular function. In conclusion, a slow electrode insertion speed appears to facilitate full electrode insertion, reduce the occurrence of insertion resistance as well as promote preservation of residual hearing and vestibular function after cochlear implantation.
在一家三级耳科/神经耳科中心进行的一项前瞻性队列研究及回顾性对照组研究中，调查电极插入速度及其对电极插入特性、听力保留和临床前庭功能的影响。
采用全身和局部类固醇联合圆窗入路、完整覆盖耳蜗的电极以及两种不同的电极插入速度[60毫米/分钟（n = 18）与15毫米/分钟（n = 22）]进行听力保留型人工耳蜗植入。
插入速度对各种插入特性以及听力保留和前庭功能有显著影响。总之，缓慢的电极插入速度似乎有助于电极完全插入，降低插入阻力的发生率，并促进人工耳蜗植入后残余听力和前庭功能的保留。
