The objective of the study was to evaluate the quality of life and benefit in patients with single-side deafness before and 1 year after cochlear implantation. In a prospective observational study design, ten adult patients with single-sided deafness undergoing cochlear implantation were included. All patients had on the implantation side no speech discrimination with normal hearing aids. The contralateral side was normal or marginal hearing loss. For determining the subject benefit from cochlear implantation, each patient answered standardized questionnaires directly before implantation and 1 year after. Regarding the questionnaire Speech, Spatial and Qualities of Hearing (SSQ), the tests yielded a significant difference in the subdomains “speech intelligibility” and “spatial hearing”. The Nijmegen Cochlear Implant Questionnaire (NCIQ) showed a significant difference in the subdomain “basic sound perception”, but not in the total score. The Glasgow Hearing Aid Benefit Profile (GHABP) showed on average moderate satisfaction in the subdomains “hearing aid benefit” and “residual disability”. In general quality of life, no significant difference was found measured by the questionnaire EQ-5D-3L. One year after cochlear implantation, most patients with single-sided deafness showed benefits in hearing as measured by validated questionnaires However, not all patients reported a significant improvement in general quality of life. Therefore, it is important to inform patients adequately and offer alternative treatments before implantation.
