OBJECTIVES: We had two sets of objectives. First, to assess the effects of an online music program on the expressive vocabulary of children with cochlear implants (CIs) and on maternal stress. Second, to explore associations between children's vocabulary, maternal stress, and the quality of children's acoustic environment, measured as daily exposure to speech in quiet. METHODS: Sixteen children with CIs ( = 17.63 months, = 6.39) and their mothers participated weekly in a 12-week online music program (CI-T), and 16 children with CIs ( = 18.46 months, = 6.02) and their mothers served as controls (CI-C). The program started three months after CI activation. Both groups were assessed at three (T1), six (T2), and twelve (T3) months after CI activation. We collected measures of children's vocabulary (using the MacArthur-Bates Cognitive Development Inventories; MB-CDI), maternal stress (using the Parenting Stress Index; PSI), and children's daily exposure to speech in quiet (from the datalogging of children's devices). Friedman non-parametric tests examined within-group differences in children's vocabulary and in mothers' stress across time points. Spearman correlations (both groups combined) explored associations between changes in vocabulary, maternal stress, and the datalogging at T1, T2, and T3. RESULTS: The CI-T group showed significant vocabulary gains between T1 and T2, and between T2 and T3 [χ²(2) = 20.5, < .001]. The CI-C group significantly improved only between T2 and T3 [χ²(2) = 19.60, < .001]. Maternal stress decreased significantly in the CI-T group between T1 and T2 [χ²(2) = 8.22, = .02], but not in the CI-C group (all s > .05). In both groups, we found significant associations between increases in children's expressive vocabulary and maternal stress (e.g. between children's vocabulary increases between T1 and T2, and mothers' scores on the 'Parent-Child Dysfunctional Interaction' subscale at T1; = -.40, = .03); between increases in children's expressive vocabulary and daily exposure to speech in quiet (e.g. between children's vocabulary increases between T1 and T2 and the datalogging 'Speech' scene at T2; = .47, = .03); and between maternal stress and daily exposure to speech in quiet (e.g. between mothers' scores on the 'Parent Distress' subscale at T2 and the datalogging 'Speech' scene at T2; = -.56, = .01) CONCLUSIONS: Online music-based interventions could benefit children with CIs and their mothers, alongside longer exposure to speech in quiet.

OBJECTIVES: Cochlear implants (CIs) have revolutionized the treatment of severe to profound sensorineural hearing loss, with life-altering outcomes for patients. CI surgery requires the surgeon to delicately place an electrode array in the scala tympani of the cochlea, a procedure that often challenges surgeons due to the absence of visual guidance. In this work, we aim to develop a vision-based tracking strategy to track the movements of the patient and the surgical tools. METHODS: A comprehensive object detection and tracking workflow tailored for temporal bone environments was developed by evaluating the performance of multiple object detection models, which were integrated with a modified BoT-SORT algorithm to enable accurate identification, segmentation, and tracking of surgical tools, electrodes, the surgeon's hands, and the patient's head across frames. The tracking strategy was trained and tested on both in-vivo and ex-vivo datasets. RESULTS: YOLOv9-based framework achieved the best performance with a mAP50 of 0.788 for detection and 0.762 for segmentation. DISCUSSION: Our findings highlight the promise of vision-based detection and tracking models in surgical settings, while also underscoring the challenges of translating performance from ex vivo to in vivo environments. CONCLUSION: The integrated YOLOv9 and BoT-SORT tracking system maintained stable identity preservation and trajectory consistency, demonstrating strong potential for real-world surgical applications.

OBJECTIVES: To evaluate the perceived utility, challenges, and opportunities for improving a regional telehealth model for cochlear implant (CI) care. METHODS: This qualitative study involved a focus group with five CI audiologists at a tertiary care center. Participants discussed their experiences with a regional telehealth program that used seven satellite sites as part of an ongoing non-inferiority trial. The transcript was analyzed using inductive thematic analysis. RESULTS: Audiologists identified regional telehealth as beneficial for routine follow-ups, troubleshooting, and reducing travel burden. Visits were shorter and more convenient for patients and providers. Challenges included difficulty communicating with patients who had cognitive or auditory limitations, limited capacity for remote troubleshooting and device handling, and lack of audiometric testing. Site variability in equipment and room acoustics also affected care quality. Participants recommended improving audiovisual infrastructure, standardizing site setups, integrating interpreter and captioning services, and expanding reimbursement. While certain populations posed greater challenges, regional telehealth was viewed as beneficial for mitigating geographic access barriers without the technological requisites for home-based telehealth. CONCLUSION: Audiologists perceived regional telehealth as a valuable adjunct to traditional CI care for improving access in underserved areas. Addressing infrastructure and workflow limitations may enhance effectiveness and support broader adoption.

OBJECTIVE: To identify major themes of interest posted by users of the foremost Facebook cochlear implant (CI) support group, understand how these users engage in online support communities, and identify educational gaps in CI care. METHODS: We conducted a retrospective thematic content analysis approach rooted in framework analysis. 536 Facebook posts were gathered over a two-week period in July 2024 from the Cochlear Implant Experiences Facebook group. Posts were analyzed for author, tone, content, and engagement metrics. Posts were inductively coded into more specific themes and subthemes by two coders with any disagreements resolved by consensus discussion. RESULTS: Majority of posts were authored by patients (81.6%), followed by unknown authors (11.8%), family members (6.2%), companies/vendors (0.2%), and providers (0.2%). The average number of reactions and comments was 22 and 20, respectively. Most posts had a neutral tone (49.6%), followed by a negative tone (28.3%), and positive tone (22.1%). Majority of posts were questions (69%), followed by experience-sharing (21%), and information-sharing posts (10%). Eight major themes were identified from the analysis. CONCLUSION: Patients utilize this social media community for various reasons but overwhelmingly utilize it to ask questions related to management of the CI device and related equipment. These findings demonstrate trust among patients to gain information from each other and seek support, providing valuable information for providers and companies to fill educational gaps in CI care.

OBJECTIVE: To present a case series of patients with Chudley - McCullough syndrome (CMS) and provide audiometric outcomes pre - and post - cochlear implantation. METHODS: A retrospective case series was written based on six patients with CMS and hearing loss. Patients were treated in a tertiary-care medical center for their hearing loss with hearing aid fitting and cochlear implantation. Audiometric outcomes pre- and post-cochlear implantation were analyzed. RESULTS: Three out of six patients were diagnosed with auditory neuropathy spectrum disorder (ANSD), one patient was suspected of ANSD, and in two patients, the presence of ANSD could neither be confirmed nor excluded. All patients were fitted with hearing aids, and all had limited benefit. In most cases, hearing deteriorated rapidly and eventually, all patients received a cochlear implant (CI), unilateral or bilateral. In general, aided thresholds with CIs were satisfactory. However, speech recognition varied widely between patients and was, on average, worse compared to patients with sensorineural hearing loss without CMS. CONCLUSIONS: CMS was often diagnosed relatively late during childhood, and sometimes hearing loss was the first apparent symptom. Hearing loss was found to be progressive, often not detected shortly after birth and often complicated by ANSD. Cochlear implantation emerged as the optimal treatment, demonstrating superiority over hearing aid rehabilitation to improve hearing performance. Auditory and speech-language development outcomes remained poorer than in children with CI and without CMS. Based on these results, we advocate considering cochlear implantation early for children who have CMS and hearing loss.

OBJECTIVES: Cochlear implantation (CI) is feasible for hearing rehabilitation in post-irradiated patients with profound sensorineural hearing loss. Complication especially explantation in patient with history of irradiation is a concern. The study aimed to investigate the incidence and cause of cochlear device explantation in between nasopharyngeal cancer (NPC)-related irradiation when compare with adults without. METHODS: This was a retrospective multicentre case-control study, which conducted on adults who underwent CI between 1994 and 2024. The rate, reasons and time after implantation of cochlear device explantation, and reimplantation rate were compared. RESULTS: A total of 1067 ears (122 ears of NPC and 945 ears of non-NPC) were included in the study. The explantation rate was significantly higher in NPC group with a percentage of 7.38% compared with 2.01% in non-NPC group (p < 0.001, OR = 3.908). There was no significant difference between the groups regarding the causes of explantation (p > 0.05). Among all the infected ears, 50% of them were infected by skin bacteria. CONCLUSIONS: This multicenter study presents regional data on post- CI explantation in patients with NPC after radiotherapy. While explantation rates were four times higher in the NPC group, no single definitive cause beyond prior radiation exposure could be identified.

OBJECTIVES: To assess the clinical relevance of the MEV in paediatric Osia implantation and its association between MEV diameter and intraoperative bleeding. METHODS: We conducted a retrospective case series of paediatric Osia implantations performed at Starship Children's Hospital between January 2022 and July 2025, comprising 52 surgeries in 39 patients. The primary outcome was incidence of intraoperative bleeding and its relationship with MEV diameter. Secondary outcomes included imaging rates and qualitative results. A parallel literature review was performed to characterise the MEV. RESULTS: Intraoperative bleeding directly attributable to injury of the MEV occurred in 3 of 52 cases (5.77%). Preoperative temporal bone CT was available in 28 cases (53.85%). Mean MEV diameter was significantly larger in bleeding compared to non-bleeding cases (5.17 ± 1.78 mm vs 1.41 ± 1.10 mm; P .03), with a large effect size. There were few post-operative complications and excellent audiometric outcomes.The paucity of literature on the MEV's surgical relevance reflects the infrequent need for posterior mastoid region dissection in standard otologic procedures. This series is the first to demonstrate a direct link between MEV diameter and bleeding risk during paediatric Osia implantation. Routine preoperative assessment of the MEV may reduce avoidable surgical complications and enhance operative saftey.

OBJECTIVES: This study investigates whether pre-implantation cognitive function, assessed using the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing Impaired Individuals (RBANS-H) correlates with speech perception oneyear post-implantation, and whether it can serve as a factor explaining unexpected outcome variability in adult Cochlear implant (CI) recipients. METHODS: This prospective longitudinal study involved 68 postlingually deaf CI recipients (ClinicalTrials.gov NCT05525221. RBANS-H assesses five cognitive domains: ), ), ), ) and ). RBANS-H and vocabulary tests were conducted pre-implantation. Phoneme scores were derived using Dutch consonant-vowel-consonant words-in-quiet, collected oneyear post-implantation in best-aided condition. RESULTS: Moderate positive correlations were observed for ( = 0.43, = 0.007), ( = 0.39, = 0.015), ( = 0.43, = 0.019), and ( = 0.34, = 0.030). No significant relationships were found for other tasks, domains, total scores or the vocabulary tests. DISCUSSION: Correlations of , and tasks with speech outcomes highlight the involvement of attention and memory in perceiving speech with CI or acquiring this ability. CONCLUSION: RBANS-H as a battery may not be sensitive enough to predict outcomes, suggesting the need for a tailored test battery that covers relevant cognitive functions and is sensitive to the specific needs of CI users.

OBJECTIVES: Broad variability exists in the outcomes of adult cochlear implant (CI) recipients. This study assessed performance of adult CI recipients on Cognivue Thrive, a quick, automated cognitive screening device applied in a private Otolaryngology practice, and assessed its ability to predict CI outcomes. METHODS: Thirty-one adults who received CIs between September 2020 and December 2022 were enrolled and tested using Cognivue Thrive before implantation. Consonant Nucleus Consonant (CNC) words and AzBio sentence recognition scores were collected early (1-3 months) and late (6-12 months) after cochlear implantation. . RESULTS: The group demonstrated poor-to-moderate mean scores relative to normative scores in the Cognivue domains of Memory, Visuospatial, and Executive Function and good performance in Reaction Time and Processing Speed. Controlling for age, the pre-operative Cognivue Memory domain score correlated positively with early post-CI CNC word score (rho = .6, P = .009) and AzBio sentence score (rho = .71, P = .002) with large effect sizes. The pre-operative Visuospatial domain score also correlated with early post-CI AzBio sentence score (rho = .62, P = .01) with large effect size. Correlations between Cognivue scores and late post-CI speech recognition were mostly weaker and non-significant. DISCUSSION: A pre-operative 5-minute, automated, visual cognitive screening test yields scores that are predictive of short-term adaptation after cochlear implantation but not longer-term speech recognition. A prospective study with larger sample is needed to validate findings. . CONCLUSION: This preliminary study demonstrates proof of concept of applying Cognivue Thrive in a private CI program and its potential to help clinicians and patients to predict CI outcomes.

OBJECTIVE: To comprehensively assess insertion characteristics, auditory performance, and cochlear implant fitting outcomes in a large cohort of implanted patients with otosclerosis, in comparison with a control group of implanted non-otosclerotic individuals. The most of the otosclerotic patients had retrofenestral otosclerosis and were indicated to cochlear implantation because of deafness. STUDY DESIGN: Retrospective observational cohort study. SETTING: Tertiary referral center. PATIENTS AND INTERVENTION: A group of 49 patients (54 implanted ears) with otosclerosis who received a Cochlear Nucleus 512 or Freedom 24RE between 2009 and 2015 were included, along with a control group of 577 patients (599 implanted ears) with hearing loss due to causes other than otosclerosis, osteogenesis imperfecta, meningitis, head trauma, temporal bone fracture, labyrinthitis, or prior middle ear surgery. All patients were implanted with the same type of electrode. MAIN OUTCOME MEASURES: Audiometric data were collected from routine fitting and re-fitting appointments using the Freiburg Monosyllabic Test and the Hochmaier-Schulz-Moser test in 10 dB noise (HSM 10 dB). Electrode impedance values, Neural Response Telemetry (NRT), C-levels, the incidence of facial nerve stimulation, and electrode deactivation during the fitting process were also assessed in both groups. For the otosclerotic patients, postoperative radiologic data included measurements of the electrode insertion angle. RESULTS: Patients in the otosclerosis group achieved a median score of 50% in the Freiburg Monosyllabic Test by the end of the first fitting week, followed by further improvement within the first year and a plateau at approximately 65%. Five years post-implantation, they achieved a mean score of 40% on the HSM 10 dB test. No statistically significant differences were observed in the audiometric test results between the otosclerosis and control groups. Impedance values in the otosclerosis group were significantly higher than in the control group. In both groups, impedances decreased after the first fitting up to the 3 months appointment, and then remained stable over the following 5 years. No statistically significant differences were observed in NRT or C-levels between the two groups. However, facial nerve stimulation occurred significantly more often in the otosclerosis group, with an incidence of 29%. The median insertion angle in the otosclerosis group was 368°, and a statistically significant positive correlation was found between insertion angle and Freiburg test scores, as determined by Pearson correlation analysis. CONCLUSION: Despite challenging anatomical conditions and increased postoperative impedances, there are no differences in audiological performance between patients undergoing cochlear implantation with compared to without otosclerosis. Patients with otosclerosis are significantly more likely to experience facial nerve stimulation. However, regarding the deactivation of electrodes overall and postoperative fitting parameters, no further differences emerge compared to the control group.

OBJECTIVES: Despite the established benefits of cochlear implantation for adults with significant hearing loss, utilisation remains low. Professional and organisational barriers may impede referral for cochlear implants (CIs). This systematic review aimed to identify and synthesise professional barriers to adult CI referral within audiological rehabilitation. METHODS: A systematic search of English-language literature was performed from January 1 1990 to May 16 2025 using Medline, CINAHL, PubMed, EMBASE and PsycINFO databases. Eighteen studies met inclusion criteria, and findings were synthesised descriptively. This systematic review was registered with PROSPERO (CRD42024540394). RESULTS: Four themes were identified as professional barriers to adult cochlear implantation: lack of knowledge and training; concerns and beliefs about CIs and patients; organisational factors; and low prioritisation of hearing loss in healthcare. DISCUSSION: Limited clinician understanding of CI candidacy criteria and referral pathways was the most frequently reported barrier. Organisational barriers included financial disincentives related to hearing aid sales and inconsistent communication between providers. Non-audiology specialists often perceived hearing loss as a lower-priority condition, contributing to under-referral despite established criteria. CONCLUSION: Improving adult CI access requires targeted clinician education, integration of CI education with hearing aids, and reduction of financial disincentives. Future research should explore patient perspectives to identify barriers and inform intervention strategies.

IMPORTANCE: Cochlear implants provide a treatment option for adults with severe to profound sensorineural hearing loss (SNHL). However, their long-term impact on mental health were understudied. OBJECTIVE: This study explored the long-term effect of cochlear implants on the incidence of psychiatric disorders in adults with bilateral severe to profound SNHL, and examined the subgroup differences in these outcomes. DESIGN, SETTING, AND PARTICIPANTS: Data for this cohort study were analyzed on January 12, 2024, from the TriNetX electronic records database. Adults with bilateral severe to profound SNHL who received a cochlear implant were compared with matched peers who did not. MAIN OUTCOMES AND MEASURES: The primary outcome was the combined incidence of anxiety, depression, and insomnia, within one to three-years after baseline. Each psychiatric disorder was examined separately as a secondary outcome. RESULTS: This study included 8,964 adults in each group. The cochlear implant group demonstrated a significant lower risk of psychiatric disorders compared to the non-implanted group. Reductions were also observed for depression, insomnia, and anxiety, with effects consistent across the follow-up period and subgroups. CONCLUSIONS: Cochlear implantation was associated with a lower long-term incidence of psychiatric disorders among adults with bilateral severe to profound SNHL.

OBJECTIVES: Cochlear implants (CIs) substantially benefit individuals with hearing loss but remain underutilized, likely due to barriers in access. This study examined how social vulnerability affects preoperative hearing loss, evaluation delays, and likelihood of CI surgery among referred adults. METHODS: This retrospective study included 120 adults referred for CI evaluation (2018-2023) who missed ≥1 evaluation appointment. Social vulnerability was assessed using the CDC Social Vulnerability Index (SVI). Associations between SVI scores and clinical variables were analyzed using t-tests and regression models. RESULTS: Higher social vulnerability correlated with younger age at referral (β = -17.9, p = 0.005) and at deafness diagnosis (β = -36.1, p = 0.007), greater travel distance (β = 124.3, p < 0.001), and longer intervals between missed appointments (β=31.1, p = 0.02). More vulnerable patients had shorter hearing-aid use, poorer audiometric thresholds, and worse word recognition scores (all p < 0.05). Overall surgical conversion was 52.6%, with non-significant trends toward lower rates in higher SVI quartiles (p = 0.10). CONCLUSION: Social vulnerability operates upstream of implantation, shaping disease progression and care access. More vulnerable adults are diagnosed earlier in life, present with more severe hearing loss, travel farther, and experience greater delays between appointments. Interventions targeting logistical barriers-including telehealth, travel support, and patient navigation-may reduce disparities and improve CI access.

OBJECTIVE: To determine the rate of vestibular dysfunction after cochlear implantation (CI), identify optimal preoperative testing to detect at-risk patients, examine correlations between objective dysfunction and symptoms, and summarize benefits of postoperative vestibular therapy. METHODS: A scoping review following PRISMA-ScR guidelines was conducted. Searches of PubMed/MEDLINE, Web of Science, Scopus, Embase, and CINAHL identified studies from inception to December 2024. RESULTS: Thirty-five studies including 2,096 adults met criteria. Preoperative vestibular dysfunction in the implanted ear was reported in 47% on caloric testing and 34.9% on cVEMP, increasing postoperatively to 65.9% and 43.1%, respectively. Subjective symptoms rose from 25.1% to 29%, with most resolving by late follow-up. Caloric testing was the most frequently used assessment (66.6%), followed by cVEMP (59.2%) and vHIT (55.5%). Combined paradigms offered the most complete evaluation. Correlation between objective dysfunction and dizziness was weak. Vestibular rehabilitation improved dizziness, balance, and DHI scores in 80-100% of treated patients. DISCUSSION: Most CI recipients experience mild and transient vestibular symptoms, though some require targeted management. CONCLUSION: A substantial proportion of CI recipients develop vestibular dysfunction, supporting the need for comprehensive preoperative assessment.

INTRODUCTION: The LittlEARS Early Speech Production Questionnaire (LEESPQ) assesses preverbal and early verbal communication in children from birth to 18 months. This study validates the Farsi LEESPQ for Iranian infants. METHODS: The LEESPQ was translated into Farsi and back-translated for accuracy. Content validity was reviewed by experts. A sample of 180 monolingual Farsi-speaking infants (birth-18 months; 10 per month) with typical hearing completed the questionnaire via their parents. We evaluated internal consistency, test-retest reliability, and criterion validity (correlation with age). Gender effects were also explored. RESULTS: The Farsi LEESPQ showed excellent internal consistency (Cronbach's α = 0.876). Age positively correlated with total scores ( 0.001), reflecting expected developmental progression. No significant gender differences were found. Age-specific normative percentile curves and minimal expected score thresholds were established. CONCLUSIONS: The Farsi LEESPQ is a reliable and valid tool for monitoring early speech development in Iranian infants up to 18 months, expanding applicability across linguistic and cultural contexts for early detection of delays.

OBJECTIVE: This study aimed to develop and validate the KBio sentence lists for assessing speech perception in children with cochlear implants (CI). METHOD: A total of 301 sentences were first rated by five teachers using a 5-point Likert scale, resulting in 172 selected sentences. These were recorded by four speakers and processed through a CI simulation to measure intelligibility in ten children with normal hearing. Based on performance, 115 sentences with ≥50% recognition were organised into five lists of twenty, with fifteen used for practice. List equivalency was evaluated in ten normal-hearing children and ten CI users across five Signal-to-Noise Ratios (SNRs). RESULTS: High content validity was confirmed through the Item Content Validity Index, Universal Agreement, and Kappa coefficients, with intelligibility ranging from 26% to 100%. One-way ANOVA showed no significant differences between lists at each SNR. Repeated-measures ANOVA with Bonferroni comparisons revealed significant effects of SNR in CI users. DISCUSSION: The KBio lists showed strong validity, high inter-rater agreement, and equivalency after CI simulation. Performance improved with increasing SNR. Variations from earlier studies may relate to linguistic factors, participant age, implantation age, and the use of speech-shaped noise. CONCLUSION: KBio comprises five validated lists influenced by background noise, with lower SNRs reducing recognition accuracy.

Cochlear implants (CIs) are the most successful neural prosthesis ever developed. While cochlear implantation was initially indicated for those with profound hearing loss, the evolving candidacy criteria has expanded to include those with low-frequency residual natural hearing. The development of ''soft'' surgical techniques has led to the ability to preserve residual hearing. This hearing preservation is particularly important for ''real-life'' listening. However, there remains a large amount of variability in rates of hearing preservation and CI outcomes. Understanding the factors that influence this variation is key. There is evidence that the overall health of the cochlea and its interaction with the CI, could potentially play a key role. Cochlear implant manufacturers have recognised this challenge, and tools to measure and monitor the health and this interaction are evolving. This editorial seeks to outline and position traditional electrophysiological testing and novel measurement tools and speculate on future utilisation in cochlear implantation.

We retrospectively analyzed pediatric patients who underwent CI surgery in our clinic, focusing on the management of Acute Otitis Media (AOM), Acute Mastoiditis (AM), and Otitis Media with Effusion (OME) in the postoperative period. METHODS: We assessed 94 CI surgeries performed in 59 pediatric patients between January 2020 and November 2023. We examined the duration of conditions, the affected ears, and the treatment approaches used. RESULTS: We identified cases of postoperative otitis media or its complications in 18 of 94 CI surgeries. Of these cases, ten were diagnosed with OME, six with AOM, and two with AM. OME cases were managed with oral antibiotics. Of six patients who developed AOM, four received intravenous antibiotics in the hospital, whereas two were treated with oral antibiotics. Two patients developed AM, one patient received only parenteral antibiotic therapy, and the other patient underwent myringotomy in addition to parenteral antibiotic therapy due to ongoing signs of infection. CONCLUSION: Postoperative OME, AOM, and AM are common complications of cochlear implant surgery. Aggressive antibiotic therapy is warranted in this specific population to prevent complications.

OBJECTIVE: To investigate the safety of magnetic resonance imaging (MRI) of cochlear implants under nonimplanted external conditions and to evaluate the potential effects of the MRI environment on their functionality. METHODS: Twelve qualified volunteers were recruited for the study, and the CS-30A cochlear implant, manufactured by Zhejiang Nurotron Biotechnology Co., Ltd., was securely positioned at the standard surgical implantation site on the head using a silicone swim cap. The implant site was marked to facilitate precise displacement measurements. MRI scans were performed under static magnetic fields of 1.5 and 3.0 T. Volunteers were systematically surveyed for pain, thermal burns, and electrical sensations. Implant displacement, magnet dislodgement or flipping, and overall device functionality, including measurements of electrode impedance, maximum stimulation amplitude, pulse width, and magnet demagnetization, were comprehensively assessed. RESULTS: The volunteers successfully completed MRI examinations under 1.5 and 3.0 T static magnetic fields without experiencing any abnormalities. After the 3.0 T MRI scan, no pain or electrical stimulation was reported, although two volunteers experienced mild warming. Similarly, after the 1.5 T MRI scan, no pain or electrical stimulation occurred, but one volunteer noted mild warming. Pre - and post-scan comparisons showed that the implant was not displaced. Electrode impedance remained within the standard range (1-20 kΩ), averaging 6.87 ± 2.45 kΩ, with no significant group differences ( > 0.05). Evaluations of implant functionality and magnet performance across monopolar 1, monopolar 2, monopolar 1 + 2 (MP1 + 2), and common ground parameters revealed no significant alterations before and after the scans ( > 0.05). DISCUSSION: This study provides important evidence supporting the clinical safety of cochlear implants under MRI conditions, ensuring their compatibility and functionality for patients requiring MRI scans. CONCLUSION: In non-implanted volunteers with the CS-30A externally affixed at the anatomical site, MRI at both 1.5 and 3.0 T produced no reports of pain, electrical-like sensations, or thermal burns. Pre- and post-scan position assessments confirmed the absence of displacement, and comprehensive functional and magnet performance testing demonstrated stable operation throughout. These device-specific findings, obtained under the tested MRI parameters, provide preliminary but important evidence supporting the compatibility of the CS-30A with MRI.

OBJECTIVES: The current study investigated the effects of processor microphone placement, microphone directionality, and remote microphone (RM) use on hearing-in-noise abilities in pediatric cochlear implant (CI) users and interactions among those technologies. METHODS: The signal-to-noise ratio required for 50%-correct recognition (SNR-50) was measured in twenty-five bilateral CI recipients using the R-SPACE in a repeated-measures design. RESULTS: For Cochlear users, behind-the-ear (BTE) microphone placement with directional settings produced better SNR-50 scores than BTE in an omnidirectional setting (Omni), but performance with an off-the-ear (OTE) placement with directional settings was not different from OTE Omni. For Advanced Bionics users, performance was better with BTE and in-the-ear (ITE) placements than OTE, and performance was better with directional microphones than without. For both manufacturers, best performance was achieved with RM. DISCUSSION: Microphone placement can have an effect on hearing-in-noise abilities, but it is moderated by microphone directionality and RM usage. SNR-50 can be improved through optimizing microphone placement and directionality, but the largest gains were obtained through use of RM. CONCLUSION: The impact of microphone placement depends on manufacturer and the use of directional and remote microphones. Findings support continued use of RM for pediatric CI users to improve hearing-in-noise.
