Nomogram for prediction of hearing rehabilitation outcome in children with congenital sensorineural hearing loss after cochlear implantation. Heliyon 2024; 10:e29529. [PMID: 38699755 PMCID: PMC11063407 DOI: 10.1016/j.heliyon.2024.e29529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 04/08/2024] [Accepted: 04/09/2024] [Indexed: 05/05/2024] Open
Abstract
Background Reliable predictors for rehabilitation outcomes in patients with congenital sensorineural hearing loss (CSNHL) after cochlear implantation (CI) are lacking. The purchase of this study was to develop a nomogram based on clinical characteristics and neuroimaging features to predict the outcome in children with CSNHL after CI. Methods Children with CSNHL prior to CI surgery and children with normal hearing were enrolled into the study. Clinical data, high resolution computed tomography (HRCT) for ototemporal bone, conventional brain MRI for structural analysis and brain resting-state fMRI (rs-fMRI) for the power spectrum assessment were assessed. A nomogram combining both clinical and imaging data was constructed using multivariate logistic regression analysis. Model performance was evaluated and validated using bootstrap resampling. Results The final cohort consisted of 72 children with CSNHL (41 children with poor outcome and 31 children with good outcome) and 32 healthy controls. The white matter lesion from structural assessment and six power spectrum parameters from rs-fMRI, including Power4, Power13, Power14, Power19, Power23 and Power25 were used to build the nomogram. The area under the receiver operating characteristic (ROC) curve of the nomogram obtained using the bootstrapping method was 0.812 (95 % CI = 0.772-0.836). The calibration curve showed no statistical difference between the predicted value and the actual value, indicating a robust performance of the nomogram. The clinical decision analysis curve showed a high clinical value of this model. Conclusions The nomogram constructed with clinical data, and neuroimaging features encompassing ototemporal bone measurements, white matter lesion values from structural brain MRI and power spectrum data from rs-fMRI showed a robust performance in predicting outcome of hearing rehabilitation in children with CSNHL after CI.

Abstract
Cochlear implantation gives children with prelingual severe hearing loss and deafness the opportunity to develop their hearing abilities, speech, language, cognitive abilities and academic skills with adequate rehabilitation. The aim of the research was to analyze verbal, figural and arithmetic fluency and their interrelationship in children with a cochlear implant (CI) and children with normal hearing (NH). A total of 46 children with CI and 110 children with NH, aged 9 to 16, participated in the research. Verbal fluency was assessed using phonemic and semantic fluency, and non-verbal fluency using figural fluency. Arithmetic fluency was assessed using simple arithmetic tasks within the number range up to 100. The results showed that children with CI achieved poorer results in phonemic fluency (z = -4.92; p < 0.001), semantic fluency (z = -3.89; p < 0.001), figural fluency (z = -3.07; p = 0.002), and arithmetic fluency (z = -4.27; p < 0.001). In both groups, a positive correlation was obtained between the measured modalities and types of fluency. In the group of children with CI, a sex difference was obtained on the phonemic fluency test, in favor of girls. The age of children with CI was correlated with arithmetic fluency. Verbal, figural and arithmetic fluency of children with CI speak in favor of the importance of early auditory and language experiences.

Abstract
Background and Objectives: Many otologists face a dilemma in the decision-making process of surgical management of patients with cochlear nerve (CN) aplasia. The goal of this study is to provide fresh evidence on cochlear implantation (CI) results in patients with CN aplasia. Materials and Methods: We scrutinized functional outcomes in 37 ears of 21 children with bilateral CN aplasia who underwent unilateral or bilateral CI based on cross-sectional and longitudinal assessments. Results: The Categories of Auditory Performance (CAP) scores gradually improved throughout the 3-year follow-up; however, variable outcomes existed between individuals. Specifically, 90% of recipients with a 1-year postoperative CAP score ≤1 could not achieve a CAP score over 1 even at 3-year postoperative evaluation, while the recipients with a 1-year postoperative CAP score >1 had improved auditory performance, and 72.7% of them were able to achieve a CAP score of 4 or higher. Meanwhile, intraoperative electrically evoked compound action potential was not correlated with postoperative CAP score. Conclusions: Our results further refine previous studies on the clinical feasibility of CI as the first treatment modality to elicit favorable auditory performance in children with CN aplasia. However, special attention should be paid to pediatric patients with an early postoperative CAP score ≤1 for identification of unsuccessful cochlear implants and switching to auditory brainstem implants.

Abstract
Some patients with severe-profound sensorineural hearing loss (SNHL) with normal cochlear anatomical structure received cochlear implantation (CI) and the hearing and speech rehabilitation effect was not ideal. Through retrospective analysis, it was found that some of these patients had cochlear never canal (CNC) stenosis, or atresia in severe cases.This article reviews the development of the CNC, the diagnostic criteria of CNC stenosis and the results of hearing and speech rehabilitation in these patients after CI.

Effects of ‘Perinatal Risk Factors Associated with Hearing Loss’ on Auditory Outcomes in Cochlear Implant Recipient Children. Indian J Otolaryngol Head Neck Surg 2022; 74:255-262.

Abstract
Cochlear implantation (CI) is used for rehabilitation of children with bilateral severe to profound permanent childhood hearing loss (PCHL). Recently, treatment of such children has been influenced by diagnostic technological advances. Children with perinatal risk factors associated with PCHL can undergo CI. The primary aim of this study was to determine the effects of 'perinatal risk factor associated with PCHL' on post-CI auditory outcomes. In this prospective study at a tertiary care centre we evaluated 50 cochlear implanted children from October 2011 to March 2013. The case group consisted of 6 (12%) children who had presence of 'perinatal risk factor associated with PCHL' and control group consisted of 44 (88%) children without any 'perinatal risk factor associated with PCHL'. All patients received auditory and speech rehabilitation and we evaluated their auditory perception outcomes by categories of auditory performance (CAP) and meaningful auditory integration scale (MAIS) scores at 1 year post-CI. There were significantly decreased mean MAIS scores (decrease of 8.6%) and mean CAP scores (decrease of 6.7%) in CI recipient children with 'perinatal risk factor associated with PCHL' as compared to those who were without any 'perinatal risk factor associated with PCHL' at 1 year after CI. However, in children with 'perinatal risk factor associated with PCHL', mean CAP & MAIS scores (auditory perception outcomes) were still more than 80% of maximum achievable CAP & MAIS scores. In this study, CI recipient children who were without any 'perinatal risk factor associated with PCHL' had significantly better mean MAIS & CAP scores (auditory perception outcomes) 1 year post-CI. However, even in children who had 'perinatal risk factor associated with PCHL', there was substantial improvement in auditory perception outcomes at 1 year post-CI and CI was still helpful in these children. Hence, knowledge of 'perinatal risk factor associated with PCHL' can provide reasonable help in predicting the auditory perception outcome and optimal counselling of families of CI candidates.

Abstract
This study aimed to assess the function of the cochlear nerve using electrically evoked compound action potentials (ECAPs) for children with cochlear implants who were diagnosed with cochlear nerve aplasia and to analyze the correlation between preimplantation imaging results and ECAP responses. Thirty-five children diagnosed with cochlear nerve aplasia based on magnetic resonance imaging (MRI) were included. Preimplantation MRI and high-resolution computed tomography (HRCT) images were reconstructed, and the width of the bone cochlear nerve canal (BCNC), the diameter of the vestibulocochlear nerve (VCN), and the diameter of the facial nerve (FN) were measured. ECAP input/output (I/O) functions were measured at three electrode locations along the electrode array for each participant. The relationship between ECAP responses (including ECAP threshold, ECAP maximum amplitude, and slope of ECAP I/O function) and sizes of the BCNC and VCN was analyzed using Pearson's correlation coefficients. Our analysis revealed that ECAP responses varied greatly among individual participants. Overall, ECAP thresholds gradually increased, while maximum amplitudes and ECAP I/O function slopes gradually decreased, as the electrode location moved from the basal to the apical direction in the cochlea. ECAP responses exhibited no significant correlations with BCNC width or VCN diameter. The ratio of the VCN to FN diameters was significantly correlated with the slope of the ECAP I/O function and the maximum amplitude. BCNC width could not predict the function of the cochlear nerve. Compared with the absolute size of the VCN, the size of the VCN relative to the FN may represent an indicator for predicting the functional status of the cochlear nerve in children diagnosed with cochlear nerve aplasia based on imaging results.

Abstract
This article summarizes the available evidence on pediatric cochlear implantation to provide current guidelines for clinical protocols and candidacy recommendations in the United States. Candidacy determination involves specification of audiologic and medical criteria per guidelines of the Food and Drug Administration. However, recommendations for a cochlear implant evaluation also should maintain flexibility and consider a child’s skill progression (i.e., month-for-month progress in speech, language, and auditory development) and quality of life with appropriately fit hearing aids. Moreover, evidence supports medical and clinical decisions based on other factors, including (a) ear-specific performance, which affords inclusion of children with asymmetric hearing loss and single-sided deafness as implant candidates; (b) ear-specific residual hearing, which influences surgical technique and device selection to optimize hearing; and (c) early intervention to minimize negative long-term effects on communication and quality of life related to delayed identification of implant candidacy, later age at implantation, and/or limited commitment to an audiologic rehabilitation program. These evidence-based guidelines for current clinical protocols in determining pediatric cochlear implant candidacy encourage a team-based approach focused on the whole child and the family system.

Abstract
OBJECTIVE Our objective was to examine the prognostic factors for post-cochlear implant (CI) communication improvement and determine whether the otologist's and speech-language pathologist's (SLP's) recommendations exhibited the same predictive performance regarding children's post-CI verbal expression acquisition. STUDY DESIGN Retrospective, diagnostic study. SETTING Hospital. PATIENTS The study reviewed 339 medical charts of preschool children who underwent CI surgery before the age of 6 years during 1999 to 2016. After these medical charts were assessed, the cohort comprised of 79 preschool children with pre- and post-CI surgery speech-language assessment reports and medical records. INTERVENTION A senior SLP and an otologist conducted blind testing of CI candidacy according to the 79 children's pre-CI reports. MAIN OUTCOME MEASURES Spoken mean length of utterance (MLU). RESULTS Children with superior skills in comprehending facial and gesture expressions or using gestures or sounds for expression were significantly more likely to receive the SLP's recommendation for CI surgery. The SLP's CI candidacy recommendation, based on background information, communication skill assessments, and magnetic resonance imaging (provided by an otologist), had significant predictive effects. Children recommended by the SLP exhibited a 20 times higher probability of benefiting from CI surgery; such a benefit would be a longer MLU after 2 years. CONCLUSION CI candidacy testing for young children with prelingual hearing impairment based on a SLP's recommendations provided significant predictive effects. LEVEL OF EVIDENCE 4 (Evidence from well-designed case-control or cohort studies).

Abstract
To evaluate various factors that affects the auditory outcomes in pediatric patients with bilateral profound sensorineural hearing loss who underwent unilateral cochlear implantation. 50 prelingually deaf pediatric patients aged between 1 and 6 years with bilateral profound sensorineural hearing loss who underwent unilateral cochlear implantation between January 2016 and June 2018 at our tertiary centre were included in this study. Auditory performance was measured using revised categories of auditory performance score at 1 year post cochlear implantation. A Statistical analysis of several factors was performed to reveal any significant relation with outcomes of cochlear implantation. The results of the study showed that patients with younger age at implantation, patient who used hearing aid prior to surgery and patients with normal cochlear morphology had better auditory outcomes post cochlear implantation than their counter group and are the factors which have positive effect on the cochlear implantation outcomes, whereas factors which did not showed any significant relation with the auditory outcomes of cochlear implantation are gender, consanguinity and birth hypoxia. Age at implantation, use of hearing aid prior to surgery and cochlear morphology are the factors with direct impact on the outcomes of cochlear implant.

Abstract
Introduction: Cochlear implants (CI) is considered a safe procedure with overall complication rate of 12.5% amongst adult and pediatric population. Cerebrospinal fluid (CSF) gusher is regarded as a common CI intraoperative complication.Objective: In this study, we determined the association between probable associated factors and occurrence of intraoperative CSF gusher.Method: In a retrospective survey, 394 patients with severe to profound sensorineural hearing loss who underwent primary cochlear implantation surgery were evaluated. Patients with incomplete electronic or manual file and those with revision, explantation or reimplantation surgery were excluded.Result: three hundred and ninety-four CI patients with a mean age of 8.74 ± 12.21 years were reviewed 49.62% of them were female. CSF gusher developed in 22 patients (5.58%). Patients with CSF gusher had more structural abnormalities in their CT scans' report. Common cavity malformation and Mondini dysplasia were the most common abnormal reports amongst those with intra-operative CSF gusher.Conclusion: In conclusion, cochlea structural abnormalities affect the incidence of CSF gusher in CI recipients. Common cavity malformation and Mondini dysplasia were associated with an increased incidence of CSF gusher. We insist on more precise pre-operative imaging of those with abnormal cochlea structures to provide the needed management.

Abstract
OBJECTIVES Bilateral duplication of the internal auditory canal (IAC) is rare and is associated with profound sensorineural hearing loss. The present study aims to review our experience with bilateral cochlear implantation (CI) in children with a duplication of the IAC and to review the literature. METHODS The Sydney Cochlear Implant Centre database was searched for children with duplication of the internal auditory canal. Data was collected regarding clinical history, MRI and CT findings, auditory brainstem responses (ABR), tympanometry and otoacoustic emissions (OAE), visually reinforced orientation audiometry, auditory brainstem response, electrocochleography (ECochG), transtympanic electrical auditory brainstem response (ABR), aided cortical evoked potentials (CAEP) and intraoperative neural response telemetry (NRT) and CI evoked electrical auditory brainstem testing. RESULTS two children with bilateral duplication of the IAC were identified who successfully underwent bilateral cochlear implantation. Audiological development was monitored for 2 and 3 years respectively, both children could spontaneously verbalise and displayed Categories of Auditory Performance (CAP) score of 5 and 6 respectively. CONCLUSION Children with duplication of the IAC, with accompanying cochlear nerve dysplasia (CND) can benefit from CI surgery, and verbal receptive and expressive language is possible.

Abstract
Background. Cochlear implantation (CI) is the main treatment method for deaf children. CI influences not only communication, but also psychosocial outcomes in children with severe to profound hearing loss. Focusing on issues specific to CI (e.g., self-reliance, social relations, education) may provide a more accurate and relative view of functional status of paediatric cochlear implant users. The objectives of this study were to translate into Lithuanian and adapt an international questionnaire of the quality of life after cochlear implantation and to evaluate parental perspectives regarding CI and the child’s progress after a minimum of two years after surgery. Materials and methods. The parental questionnaire The Children with Cochlear Implants: Parental Perspectives CCIPP was used to evaluate the quality of life following cochlear implantation. The questionnaire includes 74 items covering two main domains: decision-making (26 items) and the outcomes of implantation (48 items). Quality of life is estimated according to the scores of eight sub-domains: communication, general functioning, well-being, self-reliance, social relations, education, effects of implantation, and supporting the child. Results. The paediatric sample consisted of 11 (39%) girls and 17 (61%) boys, whose mean age at the time of cochlear implantation was 2.41 ± 2.25 years, mean duration of the implant use 3.7 ± 1.3 years. All the grand means in the outcomes of implantation domain exceeded 3 on the 5-point scale, meaning that parents viewed the quality of life of their children as either average or better. Parents rated the sub-domains of communication (3.90 ± 0.77 points), social relations (4.05 ± 0.41), and supporting the child (3.89 ± 0.49) most positively. Conclusions. According to parents, the quality of life improves after the cochlear implantation, especially in the fields of communication, social relations and supporting the child.

Does the Width of the Bony Cochlear Nerve Canal Predict the Outcomes of Cochlear Implantation? BIOMED RESEARCH INTERNATIONAL 2018; 2018:5675848. [PMID: 29750161 PMCID: PMC5884285 DOI: 10.1155/2018/5675848] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/16/2017] [Accepted: 01/22/2018] [Indexed: 11/17/2022]
Abstract
A narrow bony cochlear nerve canal (BCNC) is associated with sensorineural hearing loss necessitating cochlear implantation (CI). This study evaluated the implications of BCNC width for post-CI outcomes. A total of 56 children who had received CIs were included. The patients were divided into three groups according to the width of the BCNC (Group 1: diameter < 1.4 mm, n = 17; Group 2: diameter 1.4-2.0 mm, n = 14; Group 3: diameter > 2.0 mm, n = 25). The post-CI speech performances were compared among the three groups according to BCNC width. The correlation between BCNC width and post-CI speech performance was evaluated. Logistic regression analysis was also performed to investigate factors that can impact post-CI speech performance. Cochlear nerve deficiency (CND) occurred more frequently in Group 1. Groups 1 and 2 had significantly worse post-CI outcomes. Patients with intact cochlear nerves had significantly better post-CI outcomes than those with CND. When the cochlear nerve was intact, patients with a narrower BCNC showed less favorable results. Therefore, patients with either a narrow BCNC or CND seemed to have poorer outcomes. A narrow BCNC is associated with higher CND rates and poor outcomes. Measurement of BCNC diameter may help predict CI outcomes.
