This study highlights the effect of localisation of the fracture to morphologic, electric and functional criteria.Methods: The study group consists of patients suffering from hearing loss caused by temporal bone fracture (n = 61 ears). Patients were divided into otic capsule sparing (OCS) and otic capsule involving (OCI) fractures. The OCI group was additionally divided into subgroups with or without signs of ossification inside the cochlea. Postoperative imaging, hearing tests and electrode impedances were analysed.Results: The results of postoperative hearing rehabilitation showed lower speech understanding scores for the OCI group, especially for the ossification group. OCI fractures with signs of ossification showed increased impedances. Patients in the OCI group suffered more frequently from facial nerve stimulation (FNS). FNS was most frequently observed within the ossification group.Conclusion: Cochlear implantation in patients with temporal bone fracture is adequate therapy for the treatment of fracture-induced deafness. In long-term observation, these patients show comparable results with regular cochlear implant (CI) patients. Implantation should be performed as soon as possible after hearing loss, before obstructing obliteration or ossification of the cochlea start.","PeriodicalId":53553,"journal":{"name":"COCHLEAR IMPLANTS INTERNATIONAL","volume":"24 4","pages":"195-204"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10145319","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}

Patients with Advanced Bionics (AB) Clarion 1.2 cochlear implants may undergo CIR for device age/failure or desired technology upgrade so that they may use newer external processors that have improved connectivity features. The objective of this study was to evaluate audiologic outcomes for patients who were initially implanted with an AB Clarion 1.2 internal device and underwent CIR for technology upgrade or device failure.Methods: Retrospective chart review was performed at a single academic medical center for patients (pediatric and adult) with an AB Clarion 1.2 internal device who underwent CIR to a later generation AB internal device and had available audiologic data.Results: Forty-eight individuals with a Clarion 1.2 implant underwent CIR. Pre- and post-CIR speech understanding did not change for AzBio (p-value = 0.11, mean change = 12.1%, 95% CI = -2.9-27.2%), CNCw (p-value = 0.74, mean change = -1%, 95% CI = -10.4-12.4%), or HINT (p-value = 0.12, mean change = 19.9%, 95% CI = -2.6-42.4%) scores. Pure-tone averages improved following CIR (p-value < 0.01, mean change = 4.3 dB, 95% CI = 1.5-7.1 dB).Conclusions: Revision of AB Clarion 1.2 cochlear implants does not significantly worsen audiologic outcomes and may improve hearing in some individuals, but individual patient-level outcomes are variable.","PeriodicalId":53553,"journal":{"name":"COCHLEAR IMPLANTS INTERNATIONAL","volume":"24 4","pages":"190-194"},"PeriodicalIF":1.4,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10524760/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9791066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether the age of implantation and duration of CI use influence language development remains unclear, particularly in Mandarin-speaking children with hearing loss. Therefore, this study investigated the effects of CI-related variables on language development in these children.Methods: The present study recruited 133 Mandarin-speaking children with hearing loss, aged between 36 and 71 months chronologically, from a nonprofit organisation in Taiwan. The Revised Preschool Language Assessment (RPLA) was used to evaluate the children's language performance.Results: Children with hearing loss demonstrated delayed language comprehension and oral expression. Among them, 34% achieved age-appropriate language development. The duration of CI use had a significant direct effect on language-related abilities. Conversely, the age of implantation did not have a significant direct effect. Furthermore, the age of initial interventions (auditory-oral) had a significant direct effect only on language comprehension. Compared with the age of implantation, the duration of CI use was a significant mediator of language-related abilities.Conclusion: In Mandarin-speaking children with late CIs, the duration of CI use is a more effective mediator of language development than the age of implantation.","PeriodicalId":53553,"journal":{"name":"COCHLEAR IMPLANTS INTERNATIONAL","volume":"24 4","pages":"205-215"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9792311","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}

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.

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}
