Background: Many cochlear implant (CI) users struggle to obtain speech understanding, particularly pre-lingually deafened CI users, and the relationship between audiological performance and insertion depth is not established.
Aims: To determine audiological performance in Slovak CI users using a long flexible electrode.
Materials and Methods: Tone and speech audiometry at 1- and 5-years after CI surgery; and monosyllable word testing.
Results: Post-lingual onset of deafness CI users performed better than pre-lingual in tone audiometry after 1-year (except 250Hz) and in speech audiometry. Tone audiometry at 1-year predicted speech audiometry at 5-years in pre-lingually deafened CI users; and the speech audiometry in post-lingual at 1- and 5 years. Tone audiometry at 5-years predicted speech audiometry at 5-years. Tone audiometry at 1- and 5-years predicted the monosyllable word score in post-lingual onset of deafness CI users. In general, post-lingual onset of deafness CI users had more monosyllables correct. The pre-lingual onset of deafness CI user’s monosyllable word score was predicted by duration of deafness, but not CI use.
Conclusions and Significance:. This paper contributes to the few studies available in the Slovak language and shows that CI with a long flexible electrode improves audiological performance in pre- and post-lingually deafened CI users.
