摘要Purpose:The study aimed to investigate the otology-specific and general health-related quality of life(HRQoL)after cochlear implantation,and scrutinize the variables associated with them.Methods:The Ear Outcome Survey-16(EOS-16),which assesses ear-specific symptoms and quality of life(QoL),was administered before and after cochlear implantation along with the post-operative administration of the 15D questionnaire that evaluates general HRQoL.The authors investigated post-implantation changes in the EOS-16 total scores and its category responses,examining their relationship with pre-and post-operative hearing levels,speech perception in noise,and the follow-up period length(time elapsed since cochlear implantation).Results:There were positive changes noted for the hearing,need for care,and QoL categories of the EOS-16 after implanta-tion.The length of the follow-up period was a significant factor associated with improvements in subjective outcome measures.Changes in self-perceived hearing and HRQoL post-implantation seem independent of pre-and post-implantation hearing performance.Conclusion:These results suggest that while patients regain their hearing abilities shortly after implant activation,their subjective hearing-related benefits and QoL improve over time.
