Questions asked participants about their demographic information, device programming patterns, and attitudes regarding selective electrode deactivation.Results: Fifty-four audiologists completed the survey. When asked whether they believed selectively deactivating poorly encoded electrodes could improve speech perception outcomes, 43% of respondents selected 'Probably Yes,' 39% selected 'Definitely Yes,' and 18% selected 'Might or Might Not.' Of those who reported deactivating electrodes as part of CI programming, various methodology was reported to identify and deactivate poorly encoding electrodes and evaluate effectiveness of deactivation. General reasons against deactivation were also reported.Discussion: CI audiologists generally believed selective electrode deactivation could be used to improve speech perception outcomes for patients; however, few reported implementing selective electrode deactivation in practice. Among those who do perform selective electrode deactivation, the reported methodology was highly variable.Conclusion: These findings support the need for clinical practice guidelines to assist audiologists in performing selective electrode deactivation.","PeriodicalId":53553,"journal":{"name":"COCHLEAR IMPLANTS INTERNATIONAL","volume":"24 3","pages":"167-175"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10109200","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}

Currently, planning is usually done by multislice CT (MSCT). However, flat-panel volume CT (fpVCT) and its secondary reconstructions (fpVCTSECO) allow for more precise visualization of the cochlea. Combined with a newly developed otological planning software, the position of every single contact can be effectively predicted. In this study it was investigated how accurately radiological prediction forecasts the postoperative electrode localization and whether higher image resolution is advantageous.Methods: Utilizing otological planning software (OTOPLAN®) and different clinical imaging modalities (MSCT, fpVCT and fpVCTSECO) the electrode localization [angular insertion depth (AID)] and respective contact frequencies were predicted preoperatively and examined postoperatively. Furthermore, inter-electrode-distance (IED) and inter-electrode-frequency difference (IEFD) were evaluated postoperatively.Results: Measurements revealed a preoperative overestimation of AID. Corresponding frequencies were also miscalculated. Determination of IED and IEFD revealed discrepancies at the transition from the basal to the middle turn and round window to the basal turn. All predictions and discrepancies were lowest when using fpVCTSECO.Conclusion: The postoperative electrode position can be predicted quite accurately using otological planning software. However, because of several potential misjudgments, high-resolution imaging, such as offered by fpVCTSECO, should be used pre- and postoperatively.","PeriodicalId":53553,"journal":{"name":"COCHLEAR IMPLANTS INTERNATIONAL","volume":"24 3","pages":"144-154"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9723310","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}

Dependent variables were vocalization rate, turn taking rate, rate of speech overlap per second, and between-speaker pause duration.Results: The speech-language pathologist and children had lower rates of vocalization in the telepractice session than the in-person session. However, maternal vocalization rate was higher in the telepractice than in-person session. The rate of turn-taking between the provider and children was lower in telepractice than in-person sessions but the rate of turn taking between mothers and children was higher in telepractice than in-person sessions. Between-speaker pause duration between children and the provider and between mothers and children was longer in telepractice than in-person sessions.

'Not hearing well enough' was the most-common motivator to seek a CI. Due to the long wait for a public CI, they opted to pay for their implant privately. Funding was the most prominent barrier identified, with most participants using their own savings. The biggest struggle was in the period 3-months post switch-on. Many participants felt progress was slow and that they should have been doing better. After this period, benefits were most noted in quiet, with environmental sounds, and in helping them become more sociable. Music and telephone use were still areas many struggled with.Conclusions: Participants reported the CI was worth the cost, that they would recommend it to others, and would do it again.

Patient's speech perception scores and AFNS were compared before and after cochlear re-implantation, using monopolar stimulation associated with cathodic biphasic pulses and multi-mode stimulation mode associated to anodic monophasic pulses, respectively. The insertion depth angle and the electrode-nerve distances were also investigated, before and after cochlear re-implantation. Results: AFNS was resolved, and the speech recognition scores rapidly increased in the first year after cochlear re-implantation while remaining stable. After cochlear re-implantation, the e15 and e20 electrodes showed shorter electrode-nerve distances compared to their correspondent e4 and e7 electrodes, which induced AFNS in the first implantation.

In IOSO group, 3rd month's electrode impedances were high when compared to electrode impedances at Switch ON. Beyond the 3rd months, electrode impedance remained unchanged. In POSO group, there were no significant differences in electrode impedances between any measurement schedule.Conclusions: To our knowledge, this is the first study to investigate in detail the electrode impedances of the two above-said conditions of Switch ON in the process of cochlear implantation.

Of those, 7 patients (8 ears) demonstrated intracochlear fibrosis.Interventions: CI performed 1-4 months following meningitis/labyrinthitis and 12-24 months after idiopathic sudden SNHL. Fibrosis removal (38%) or dilation (63%) permitted implantation. A styleted-electrode was used in 63% due to dense fibrosis.Main outcome measures: Postoperative audiometry with CI in place, additional comparisons with audiometric outcomes in age-matched controls.Results: Full insertion achieved in all except one ear with partial ossification. Mean ipsilateral pure tone average (PTA) improved to 29 ± 15 dB and speech discrimination to 72 ± 28%. Fibrosis removal vs. dilation resulted in no PTA differences (p = 0.76).
