The aim of this paper was to examine the influence of progressive hearing loss and different causes that had led to the hearing loss on the results of cochlear implantation. The heterogeneity of the population hinders rehabilitation and requires a detailed approach, therefore, for the purposes of the study we grouped the participants on the basis of common ground with regard to the time of the hearing loss and the factors that led to the hearing loss. We monitored the progressive decay of hearing over time and tried to find how it affected the results achieved after cochlear implantation. The study was conducted on a sample of thirty patients aged between 33-80 years with sensorineural hearing loss where the hearing loss occurred postlingually and who have met the criteria for the cochlear implantation. According to Clark et al. (2012), the duration of progressive hearing loss does not affect the results after cochlear implantation which proved to be correct for the majority of participants in this study. When the results after the cochlear implantation were worse, that was the case with the participants whose hearing loss lasted between 20 and 60 years. The results based on the different time span between diagnosed deafness and cochlear implantation of the participants showed no significant differences in the results after cochlear implantation, which is contrary to our initial assumption and research of Peterson et al. (2010). With regard to the causes of hearing loss, we expected that the results would be different, which proved to be accurate, but the differences in this study are insufficient for concrete conclusions. The research showed that participants who continued to use the hearing aid contralaterally had better results than other participants (Group D), which is in line with research of Firszt et al. (2012). Due to the large individual differences among subjects and arbitrary division according to aforementioned criteria, we believe that monitoring the results over a longer period of time after cochlear implantation and testing of cognitive abilities of the participants before and after cochlear implantation would be the first step in order to get a more detailed insight into the factors that influence the results after cochlear implantation.
