Abstract
As part of a longitudinal study regarding the benefit of early cochlear implantation for children with single-sided deafness, the current work explored the children's daily device use, potential barriers to full-time device use, and the children's ability to understand speech with the cochlear implant (CI). Data were collected from 20 children with prelingual SSD who received a CI before the age of 2.5 years, from the initial activation of the sound processor until the children were 4.8 to 11.0 years old. Daily device use was extracted from the CI's data logging, while word perception in quiet was assessed using direct audio input to the children's sound processor. The children's caregivers completed a questionnaire about habits, motivations, and barriers to device use. The children with SSD and a CI used their device on average 8.3 h per day, corresponding to 63 % of their time spent awake. All children except one could understand speech through the CI, with an average score of 59 % on a closed-set test and 73 % on an open-set test. More device use was associated with higher speech perception scores. Parents were happy with their decision to pursue a CI for their child. Certain habits, like taking off the sound processor during illness, were associated with lower device use. Providing timely counselling to the children's parents, focused on SSD-specific challenges, may be helpful to improve daily device use in these children.

Abstract
OBJECTIVE Unilateral hearing loss (UHL) in children is associated with speech and language delays. Cochlear implantation (CI) is currently the only rehabilitative option that restores binaural hearing. This study aims to describe auditory outcomes in children who underwent CI for UHL and to determine the association between duration of hearing loss and auditory outcomes. STUDY DESIGN Retrospective case series. SETTING Three tertiary-level, academic institutions. PATIENTS Children <18 years with UHL who underwent CI between 2018 and 2021. INTERVENTION Cochlear implantation. MAIN OUTCOME MEASURES Speech perception and Speech, Spatial and Qualities of Hearing Scale (SSQ) were assessed postimplantation. Scores >50% on speech perception and SSQ scores >8 points were considered satisfactory. Associations between duration of UHL and implantation age and outcomes were assessed using Spearman's rank correlation. RESULTS Of the 38 children included, mean age at CI was 7.9 ± 3.2 years and mean UHL duration was 5.0 ± 2.8 years. Mean datalogging was 8.1 ± 3.1 hours/day. Mean auditory testing scores were SSQ, 7.9 ± 1.2; BABY BIO, 68.1 ± 30.2%; CNC, 38.4 ± 28.4%; WIPI, 52.5 ± 23.1%. Scores >50% on CNC testing were achieved by 40% of patients. SSQ scores >8 points were reported by 78% (7/9) of patients. There were no significant correlations between UHL duration and auditory outcomes. CONCLUSION Overall, children with UHL who undergo CI can achieve satisfactory speech perception scores and SSQ scores. There were no associations between duration of hearing loss and age at implantation with auditory outcomes. Multiple variables may impact auditory outcomes, including motivation, family support, access to technology, and consistent isolated auditory training postactivation and should be taken into consideration in addition to age at implantation and duration of UHL in determination of CI candidacy.

Abstract
OBJECTIVE To assess the perceived benefit of cochlear implant (CI) use for children with unilateral hearing loss (UHL) and evaluate whether perceived abilities are associated with performance on measures of speech recognition and spatial hearing. METHOD Nineteen children with moderate-to-profound UHL underwent cochlear implantation. The Speech Spatial and Qualities of Hearing Questionnaire modified for children (SSQ-C) were completed by parental proxy pre-operatively and at 3, 6, 9, 12, 18, and 24 months post-activation. Linear mixed models evaluated perceived benefits over the study period. Pearson correlations assessed the association between subjective report and performance on measures of word recognition with the CI alone and spatial hearing (speech recognition in spatially-separated noise and sound source localization) in the combined condition (CI plus contralateral ear). RESULTS For the SSQ-C, parents reported significant improvements with CI use as compared to pre-operative perceptions (p < 0.001); improved perceptions were either maintained or continued to improve over the 2-year post-activation period. Perceived benefit did not significantly correlate with word recognition with the CI alone or spatial hearing outcomes in the combined condition. CONCLUSION Families of children with UHL observed benefits of CI use early after cochlear implantation that was maintained with long-term device use. Responses to subjective measures may broaden our understanding of the experiences of pediatric CI users with UHL in addition to outcomes on typical measures of CI performance.

Abstract
Introduction Single sided deafness (SSD) results in profound cortical reorganization that presents clinically with a significant impact on sound localization and speech comprehension. Cochlear implantation (CI) has been approved for two manufacturers' devices in the United States to restore bilateral function in SSD patients with up to 10 years of auditory deprivation. However, there is great variability in auditory performance and it remains unclear how auditory deprivation affects CI benefits within this 10-year window. This prospective study explores how measured auditory performance relates to real-world experience and device use in a cohort of SSD-CI subjects who have between 0 and 10 years of auditory deprivation. Methods Subjects were assessed before implantation and 3-, 6-, and 12-months post-CI activation via Consonant-Nucleus-Consonant (CNC) word recognition and Arizona Biomedical Institute (AzBio) sentence recognition in varying spatial speech and noise presentations that simulate head shadow, squelch, and summation effects (S0N0, SSSDNNH, SNHNSSD; 0 = front, SSD = impacted ear, NH = normal hearing ear). Patient-centered assessments were performed using Tinnitus Handicap Inventory (THI), Spatial Hearing Questionnaire (SHQ), and Health Utility Index Mark 3 (HUI3). Device use data was acquired from manufacturer software. Further subgroup analysis was performed on data stratified by <5 years and 5-10 years duration of deafness. Results In the SSD ear, median (IQR) CNC word scores pre-implant and at 3-, 6-, and 12-months post-implant were 0% (0-0%), 24% (8-44%), 28% (4-44%), and 18% (7-33%), respectively. At 6 months post-activation, AzBio scores in S0N0 and SSSDNNH configurations (n = 25) demonstrated statistically significant increases in performance by 5% (p = 0.03) and 20% (p = 0.005), respectively. The median HUI3 score was 0.56 pre-implant, lower than scores for common conditions such as anxiety (0.68) and diabetes (0.77), and comparable to stroke (0.58). Scores improved to 0.83 (0.71-0.91) by 3 months post-activation. These audiologic and subjective benefits were observed even in patients with longer durations of deafness. Discussion By merging CI-associated changes in objective and patient-centered measures of auditory function, our findings implicate central mechanisms of auditory compensation and adaptation critical in auditory performance after SSD-CI and quantify the extent to which they affect the real-world experience reported by individuals.

Abstract
OBJECTIVES Children with severe-to-profound unilateral hearing loss, including cases of single-sided deafness (SSD), lack access to binaural cues that support spatial hearing, such as recognizing speech in complex multisource environments and sound source localization. Listening in a monaural condition negatively impacts communication, learning, and quality of life for children with SSD. Cochlear implant (CI) use may restore binaural hearing abilities and improve outcomes as compared to alternative treatments or no treatment. This study investigated performance over 24 months of CI use in young children with SSD as compared to the better hearing ear alone and to children with bilateral normal hearing (NH). DESIGN Eighteen children with SSD who received a CI between the ages of 3.5 and 6.5 years as part of a prospective clinical trial completed assessments of word recognition in quiet, masked sentence recognition, and sound source localization at regular intervals out to 24-month postactivation. Eighteen peers with bilateral NH, matched by age at the group level, completed the same test battery. Performance at 24-month postactivation for the SSD group was compared to the performance of the NH group. RESULTS Children with SSD have significantly poorer speech recognition in quiet, masked sentence recognition, and localization both with and without the use of the CI than their peers with NH. The SSD group experienced significant benefits with the CI+NH versus the NH ear alone on measures of isolated word recognition, masked sentence recognition, and localization. These benefits were realized within the first 3 months of use and were maintained through the 24-month postactivation interval. CONCLUSIONS Young children with SSD who use a CI experience significant isolated word recognition and bilateral spatial hearing benefits, although their performance remains poorer than their peers with NH.

Abstract
Introduction Candidacy criteria for cochlear implantation in the United States has expanded to include children with single-sided deafness (SSD) who are at least 5 years of age. Pediatric cochlear implant (CI) users with SSD experience improved speech recognition with increased daily device use. There are few studies that report the hearing hour percentage (HHP) or the incidence of non-use for pediatric CI recipients with SSD. The aim of this study was to investigate factors that impact outcomes in children with SSD who use CIs. A secondary aim was to identify factors that impact daily device use in this population. Methods A clinical database query revealed 97 pediatric CI recipients with SSD who underwent implantation between 2014 and 2022 and had records of datalogs. The clinical test battery included speech recognition assessment for CNC words with the CI-alone and BKB-SIN with the CI plus the normal-hearing ear (combined condition). The target and masker for the BKB-SIN were presented in collocated and spatially separated conditions to evaluate spatial release from masking (SRM). Linear mixed-effects models evaluated the influence of time since activation, duration of deafness, HHP, and age at activation on performance (CNC and SRM). A separate linear mixed-effects model evaluated the main effects of age at testing, time since activation, duration of deafness, and onset of deafness (stable, progressive, or sudden) on HHP. Results Longer time since activation, shorter duration of deafness, and higher HHP were significantly correlated with better CNC word scores. Younger age at device activation was not found to be a significant predictor of CNC outcomes. There was a significant relationship between HHP and SRM, with children who had higher HHP experiencing greater SRM. There was a significant negative correlation between time since activation and age at test with HHP. Children with sudden hearing loss had a higher HHP than children with progressive and congenital hearing losses. Conclusion The present data presented here do not support a cut-off age or duration of deafness for pediatric cochlear implantation in cases of SSD. Instead, they expand on our understanding of the benefits of CI use in this population by reviewing the factors that influence outcomes in this growing patient population. Higher HHP, or greater percentage of time spent each day using bilateral input, was associated with better outcomes in the CI-alone and in the combined condition. Younger children and those within the first months of use had higher HHP. Clinicians should discuss these factors and how they may influence CI outcomes with potential candidates with SSD and their families. Ongoing work is investigating the long-term outcomes in this patient population, including whether increasing HHP after a period of limited CI use results in improved outcomes.

Abstract
PURPOSE Unilateral cochlear implants (CIs) can restore binaural hearing in single-sided deafness (SSD). Direct stimulation of the CI can be obtained via the Bluetooth connection of a device to the CI, thus excluding the typical-hearing ear. This study aims to investigate the use of CI connectivity features as a rehabilitative strategy in a small cohort of children affected by SSD. METHOD A newly developed training protocol was presented to children with SSD who have less than 2 years of experience with CI. We developed a user-friendly and short-term (six sessions within 20 days) training protocol for speech perception that patients themselves can manage independently at home using CI connectivity systems. Children were telematically tested before and after the training by trained speech and language therapists. RESULTS Four patients met the inclusion criteria. They all showed better results in the final online assessment, when compared with the initial one. CONCLUSIONS To our knowledge, this is the first clinical focus article presenting an auditory training protocol for SSD patients with CI using the Bluetooth connectivity systems for teletherapy. The results, although preliminary, support the efficacy of this rehabilitative strategy. Further research is needed to support our findings.

Abstract
Cochlear implants (CIs) allow to restore the hearing function in profoundly deaf individuals. Due to the degradation of the stimulus by CI signal processing, implanted individuals with single-sided deafness (SSD) have the specific challenge that the input highly differs between their ears. The present study compared normal-hearing (NH) listeners (N = 10) and left- and right-ear implanted SSD CI users (N = 10 left, N = 9 right), to evaluate cortical speech processing between CI- and NH-ears and to explore for side-of-implantation effects. The participants performed a two-deviant oddball task, separately with the left and the right ear. Auditory event-related potentials (ERPs) in response to syllables were compared between proficient and non-proficient CI users, as well as between CI and NH ears. The effect of the side of implantation was analysed on the sensor and the source level. CI proficiency could be distinguished based on the ERP amplitudes of the N1 and the P3b. Moreover, syllable processing via the CI ear, when compared to the NH ear, resulted in attenuated and delayed ERPs. In addition, the left-ear implanted SSD CI users revealed an enhanced functional asymmetry in the auditory cortex than right-ear implanted SSD CI users, regardless of whether the syllables were perceived via the CI or the NH ear. Our findings reveal that speech-discrimination proficiency in SSD CI users can be assessed by N1 and P3b ERPs. The results contribute to a better understanding of the rehabilitation success in SSD CI users by showing that cortical speech processing in SSD CI users is affected by CI-related stimulus degradation and experience-related functional changes in the auditory cortex.

Abstract
Objectives/Hypotheses Children with unilateral sensory hearing loss (UHL) struggle to understand speech in noise and locate the origin of sound and have reduced quality of hearing. This clinical trial will determine the benefits of cochlear implantation in children with UHL. Study Design Prospective clinical trial. Methods Twenty children with at least moderate to profound sensory hearing loss and poor speech perception (word score <30%) in one ear and normal hearing in the contralateral ear participated in a Food and Drug Administration‐approved clinical trial. Subjects were evaluated for speech perception in quiet, speech perception in noise, sound localization, and subjective benefits after implantation. Results CNC word score perception in quiet significantly improved (1% to 50%, P < .0001) by 12 months after activation. Speech perception in noise by BKB‐SIN significantly improved in all three noise configurations; there was a 3.6 dB advantage in head shadow (P < .0001), a 1.6 dB advantage in summation (P = .003), and a 2.5 dB advantage in squelch (P = .0001). Localization improved by 26° at 9 months (P < .0001). Speech, Spatial, and Qualities (SSQ) demonstrated significant improvements in speech (5.2 to 7.4, P = .0012), qualities of hearing (5.9 to 7.5, P = .0056), and spatial hearing (2.7 to 6.6, P < .0001). SSQ subscales associated with binaural hearing were significantly improved, as was listening effort (P = .0082). Subjects demonstrated a non‐significant improvement in fatigue. Conclusions This study demonstrates that children with UHL significantly benefit from cochlear implantation. Level of Evidence Level 3 Laryngoscope, 132:S1–S18, 2022
