Common ground electrode impedances, pre- and post-operative hearing thresholds and CNC word recognition scores were retrieved.Results: Electrode impedances were significantly higher for recipients of the straight electrode array. Within individuals, electrode impedances were stable after the first week post-activation. However, increased standard deviation of electrode impedances was associated with greater loss of low frequency hearing at initial activation, and with poorer speech recognition at 6 months post-implantation.Conclusions: Results demonstrate that electrode impedances depend on the type of implanted array. Findings also suggest that there may be a role for the variability in electrode impedance across electrodes as an indicator of changes in the intracochlear environment that contribute to outcomes with a CI.","PeriodicalId":53553,"journal":{"name":"COCHLEAR IMPLANTS INTERNATIONAL","volume":" ","pages":"59-68"},"PeriodicalIF":1.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138800515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesize that ceiling effects are highly prevalent for most tests.Design: Retrospective chart review of children receiving a CI between 2002 and 2014.Results: 165 children were included. Median scores were above ceiling levels (≥90% correct) for the majority of speech perception tests and all distributions of scores were highly skewed. Children who were implanted earlier, received two implants, and were oral communicators were more likely to reach ceiling-level performance. Age and years of CI listening experience at time of test were negatively correlated with performance, suggesting a non-random assignment of tests.

Patients who underwent CI over a 22-year period (1999-2021) and had videonystagmography (VNG) testing pre- and postimplantation were included. Caloric responses were compared pre- versus post-implantation, and assessed for their ability to predict CI performance as evaluated using AzBio +10 decibels signal-to-noise ratio (dB S/N) scores.Results: 43 CI recipients were included. There was a significant difference in the average maximal slow-phase velocity in response to caloric irrigation in the implanted ear pre- versus post-operatively (21.2 vs. 18.5 deg/s; p = 0.02). Controlling for age and pre-implantation speech recognition performance, pre- and post-implantation caloric responses in the implanted ear significantly predicted CI performance at 0-6 months and >6 months post-implantation.

According to speech recognition scores and pure-tone thresholds, the study group was further subdivided into two subgroups: 24 children with excellent auditory performance and 10 children with fair auditory performance.
