Cereb Cortex 2024; 34:bhae145.

Abstract
Hearing is critical to spoken language, cognitive, and social development. Little is known about how early auditory experiences impact the brain structure of children with bilateral sensorineural hearing loss. This study examined the influence of hearing aid use and residual hearing on the auditory cortex of children with severe to profound congenital sensorineural hearing loss. We evaluated cortical preservation in 103 young pediatric cochlear implant candidates (55 females and 48 males) by comparing their multivoxel pattern similarity of auditory cortical structure with that of 78 age-matched children with typical hearing. The results demonstrated that early-stage hearing aid use preserved the auditory cortex of children with bilateral congenital sensorineural hearing loss. Children with less residual hearing experienced a more pronounced advantage from hearing aid use. However, this beneficial effect gradually diminished after 17 months of hearing aid use. These findings support timely fitting of hearing aids in conjunction with early implantation to take advantage of neural preservation to maximize auditory and spoken language development.

Abstract
OBJECTIVE Several studies have shown that cochlear implantation (CI) can influence language development in children with severe-to-profound hearing loss. 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.

Abstract
OBJECTIVES This study investigated age at implantation, improvement in hearing and speech perception outcomes, as well as surgical complications in pediatric cochlear implant recipients with Pendred Syndrome (PS) or non-syndromic enlarged vestibular aqueduct (NSEVA). DESIGN A systematic review of the literature between 1984 and 2021 was performed. Two independent reviewers performed abstract and full-text screening using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The inclusion criteria were: English language, cochlear implant, age at implantation available, age <18 years, PS, Mondini malformation, and enlarged vestibular aqueduct. Full-text analysis was completed using the National Institute of Health assessment tool for case series and case-control studies. Studies were also graded according to the Oxford Centre for Evidence-Based Medicine grading system. RESULTS In total, 198 studies were identified and screened, and 55 studies were included for analysis. Audiological outcomes were available in 46 studies, and the four-frequency pure-tone audiogram average improved by 60 to 78 dB HL due to cochlear implantation. Auditory performance and speech intelligibility scores increased by 44%. The overall average implantation age was 60 months. The implantation age was 21 months lower in the studies where individuals were implanted after the year 2000 compared with those implanted before the year 2000. Perilymph gusher/oozing was the most common surgical incident reported, occurring in 187 of 1572 implantations. CONCLUSIONS In children with PS/NSEVA, cochlear implantation improves pure-tone average by 60 to 78 dB HL and capacity of auditory performance/speech intelligibility by 44%. The implantation age for these children has decreased during the last two decades but is still somewhat higher than reported for unselected pediatric cochlear implantation. Perilymph gusher/oozing is the most common surgical complication.

Abstract
(1) Background: There is clear evidence supporting the need for individualized early intervention in children with hearing loss. However, relying on hearing thresholds and speech and language test results to guide intervention alone is problematic, particularly in infants and young children. This study aimed to establish the feasibility of a tool to monitor the development of functional listening skills to inform early and ongoing decisions by parents and professionals. (2) Methods: The FLI-P® is a 64-item checklist completed by parents and/or a child’s team. The listening development of 543 children with hearing loss enrolled in an early intervention and cochlear implant program was tracked with the FLI-P over a 6-year period. The scores for individual children were grouped according to hearing loss, device, additional needs, and age at device fitting. (3) Results: Results indicate that the FLI-P is a feasible and viable clinical measure that can be used to identify and track a child’s developing listening skills. Its use across a wide range of children supports its broad application. Children’s individual scores and aggregated group data were consistent with indicated expected differences and variations. Children’s individual scores and aggregated group data indicated expected differences and variations. (4) Conclusions: Information provided by children’s listening scores on the FLI-P can guide and support discussions and intervention decisions and bridge the gap between information from audiological assessments and language measures.

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.

Links of Prosodic Stress Perception and Musical Activities to Language Skills of Children With Cochlear Implants and Normal Hearing. Ear Hear 2021; 41:395-410.

Abstract
OBJECTIVES A major issue in the rehabilitation of children with cochlear implants (CIs) is unexplained variance in their language skills, where many of them lag behind children with normal hearing (NH). Here, we assess links between generative language skills and the perception of prosodic stress, and with musical and parental activities in children with CIs and NH. Understanding these links is expected to guide future research and toward supporting language development in children with a CI. DESIGN Twenty-one unilaterally and early-implanted children and 31 children with NH, aged 5 to 13, were classified as musically active or nonactive by a questionnaire recording regularity of musical activities, in particular singing, and reading and other activities shared with parents. Perception of word and sentence stress, performance in word finding, verbal intelligence (Wechsler Intelligence Scale for Children (WISC) vocabulary), and phonological awareness (production of rhymes) were measured in all children. Comparisons between children with a CI and NH were made against a subset of 21 of the children with NH who were matched to children with CIs by age, gender, socioeconomic background, and musical activity. Regression analyses, run separately for children with CIs and NH, assessed how much variance in each language task was shared with each of prosodic perception, the child's own music activity, and activities with parents, including singing and reading. All statistical analyses were conducted both with and without control for age and maternal education. RESULTS Musically active children with CIs performed similarly to NH controls in all language tasks, while those who were not musically active performed more poorly. Only musically nonactive children with CIs made more phonological and semantic errors in word finding than NH controls, and word finding correlated with other language skills. Regression analysis results for word finding and VIQ were similar for children with CIs and NH. These language skills shared considerable variance with the perception of prosodic stress and musical activities. When age and maternal education were controlled for, strong links remained between perception of prosodic stress and VIQ (shared variance: CI, 32%/NH, 16%) and between musical activities and word finding (shared variance: CI, 53%/NH, 20%). Links were always stronger for children with CIs, for whom better phonological awareness was also linked to improved stress perception and more musical activity, and parental activities altogether shared significantly variance with word finding and VIQ. CONCLUSIONS For children with CIs and NH, better perception of prosodic stress and musical activities with singing are associated with improved generative language skills. In addition, for children with CIs, parental singing has a stronger positive association to word finding and VIQ than parental reading. These results cannot address causality, but they suggest that good perception of prosodic stress, musical activities involving singing, and parental singing and reading may all be beneficial for word finding and other generative language skills in implanted children.

Abstract
Questions about communication mode (a.k.a. "communication options" or "communication opportunities") remain among the most controversial issues in the many fields that are concerned with the development and well-being of children (and adults) who are d/Deaf or hard of hearing. In this manuscript, we argue that a large part of the reason that this debate persists is due to limitations of the construct itself. We focus on what we term "the crucial question": namely, what kind of experience with linguistic input during infancy and toddlerhood is most likely to result in mastery of at least one language (spoken or signed) by school entry. We argue that the construct of communication mode-as currently construed-actively prevents the discovery of compelling answers to that question. To substantiate our argument, we present a review of a relevant subset of the recent empirical literature and document the prevalence of our concerns. We conclude by articulating the desiderata of an alternative construct that, if appropriately measured, would have the potential to yield answers to what we identify as "the crucial question."

Abstract
Purpose The study sought to determine whether the onset of canonical vocalizations in children with cochlear implants (CIs) is related to speech perception skills and spoken vocabulary size at 24 months postactivation. Method The vocal development in 13 young CI recipients (implanted by their third birthdays; mean age at activation = 20.62 months, SD = 8.92 months) was examined at every 3-month interval during the first 2 years of CI use. All children were enrolled in auditory-oral intervention programs. Families of these children used spoken English only. To determine the onset of canonical syllables, the first 50 utterances from 20-min adult-child interactions were analyzed during each session. The onset timing was determined when at least 20% of utterances included canonical syllables. As children's outcomes, we examined their Lexical Neighborhood Test scores and vocabulary size at 24 months postactivation. Results Pearson correlation analysis showed that the onset timing of canonical syllables is significantly correlated with phonemic recognition skills and spoken vocabulary size at 24 months postactivation. Regression analyses also indicated that the onset timing of canonical syllables predicted phonemic recognition skills and spoken vocabulary size at 24 months postactivation. Conclusion Monitoring vocal advancement during the earliest periods following cochlear implantation could be valuable as an early indicator of auditory-driven language development in young children with CIs. It remains to be studied which factors improve vocal development for young CI recipients.

Abstract
Purpose Normal-hearing (NH) children acquire plural morphemes at different rates, with the segmental allomorphs /-s, -z/ (e.g., cat-s) being acquired before the syllabic allomorph /-əz/ (e.g., bus-es). Children with hearing loss (HL) have been reported to show delays in the production of plural morphology, raising the possibility that this might be due to challenges acquiring different types of lexical/morphological representations. This study therefore examined the comprehension of plural morphology by 3- to 7-year-olds with HL and compared this with performance by their NH peers. We also investigated comprehension as a function of wearing hearing aids (HAs) versus cochlear implants (CIs). Method Participants included 129 NH children aged 3-5 years and 25 children with HL aged 3-7 years (13 with HAs, 12 with CIs). All participated in a novel word two-alternative forced-choice task presented on an iPad. The task tested comprehension of the segmental (e.g., teps, mubz) and syllabic (e.g., kosses) plural, as well as their singular counterparts (e.g., tep, mub, koss). Results While the children with NH were above chance for all conditions, those with HL performed at chance. As a group, the performance of the children with HL did not improve with age. However, results suggest possible differences between children with HAs and those with CIs, where those with HAs appeared to be in the process of developing representations of consonant-vowel-consonant singulars. Conclusions Results suggest that preschoolers with HL do not yet have a robust representation of plural morphology for words they have not heard before. However, those with HAs are beginning to access the singular/plural system as they get older.

Abstract
Introduction The cochlear implant is an effective device for children with severe and/or profound prelingual hearing loss, since it provides considerable improvement in oral language acquisition through the auditory pathway. The use of a cochlear implant contributes to the development of auditory perception, favoring the acquisition of the linguistic processes related to communication skills, which might have a positive effect on other areas of development. Objective The aim of this study was to verify the performance of children using cochlear implants for expressive and receptive oral language. Methods This was a prospective cross-sectional study that used the following tests: Child language test in the phonology, vocabulary, fluency and pragmatics areas, and the Peabody picture vocabulary test. Thirty children participated in this study, of both genders, aged between 36 and 72 months, with severe and/or profound bilateral sensorineural hearing loss, without other impairments and users of unilateral cochlear implant with full electrode insertion for a minimum of 12 months. Results The longer duration of the cochlear implant use, the younger age at surgery and the better performance in the auditory perception of speech influenced the performance in expressive and receptive oral language. Even though when compared to the normative language acquisition process, the results showed that these children had patterns of linguistic skills that are below their chronological age; the results indicate that these children are developing expressive and receptive oral language skills, and this is the outcome that should be taken into account in this study. Conclusion The longer duration of the cochlear implant use, the younger age at surgery and the better performance in the auditory perception of speech influenced the performance in expressive and receptive oral language skills, but not in all the studied semantic categories.

Abstract
Effects of music on language processing have been reported separately for syntax and for semantics. Previous studies have shown that regular musical rhythms can facilitate syntax processing and that semantic features of musical excerpts can influence semantic processing of words. It remains unclear whether musical parameters, such as rhythm and sound texture, may specifically influence different components of linguistic processing. In the current study, two types of musical sequences (one focusing on rhythm and the other focusing on sound texture) were presented to children who were requested to perform a syntax or a semantic task thereafter. The results revealed that rhythmic and textural musical sequences differently influence syntax and semantic processing. For grammaticality judgments, children's performance was better after regular rhythmic sequences than after textural sound sequences. In the semantic evocation task, children produced more numerous and more various concepts after textural sound sequences than after regular rhythmic sequences. These results suggest that rhythm boosts perceptual and cognitive sequencing required in syntax processing, whereas texture promote verbalization and concept activation in verbal production. The findings have implications for the interpretation of musical priming effects and are discussed in the frameworks of dynamic attending and conceptual processing.

Abstract
Purpose The increasing prevalence of pediatric cochlear implantation over the past 25 years has left little doubt that resulting improvements in hearing offer significant benefits to language development for many deaf children. Furthermore, given the documented importance of access to language from birth, there has been strong support for providing congenitally deaf children with implants as early as possible. Earliest implantation, in many ways, has become the "gold standard" in pediatric cochlear implantation, on the assumption that it is the key to language development similar to that of hearing children. Empirical evidence to support this assumption, however, appears more equivocal than generally is believed. This article reviews recent research aimed at assessing the impact of age at implantation on vocabulary and grammatical development among young implant users. Method Articles published between 2003 and 2018 that included age at implantation as a variable of interest and in which it was subjected to statistical analysis were considered. Effect sizes were calculated whenever possible; we conducted a multivariate meta-analysis to compare outcomes in different language domains. Results Taken together, findings from 49 studies suggest that age at implantation is just one of a host of variables that influence vocabulary and grammatical development, its impact varying with several factors including whether age at implantation is treated as a dichotomous or continuous variable. Results from a meta-analysis showed significant differences across language domains. Conclusion The pattern of results obtained indicates the importance of considering various child, family, and environmental characteristics in future research aimed at determining how early "early implantation" needs to be and the extent to which age at implantation, duration of implant use, and other factors influence language and language-related outcomes.

Age-sensitive associations of segmental and suprasegmental perception with sentence-level language skills in Mandarin-speaking children with cochlear implants. RESEARCH IN DEVELOPMENTAL DISABILITIES 2019; 93:103453. [PMID: 31421305 DOI: 10.1016/j.ridd.2019.103453] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2018] [Revised: 07/22/2019] [Accepted: 07/28/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND AND AIM It remains unclear how recognition of segmental and suprasegmental phonemes contributes to sentence-level language processing skills in Mandarin-speaking children with cochlear implants (CIs). Our study examined the influence of implantation age on the recognition of consonants, lexical tones and sentences respectively, and more importantly, the contribution of phonological skills to sentence repetition accuracy in Mandarin-speaking children with CIs. METHODS The participants were three groups of prelingually deaf children who received cochlear implants at various ages and their age-matched controls with normal hearing. Three tasks were administered to assess their consonant perception, lexical tone recognition and language skills in open-set sentence repetition. RESULTS Children with CIs lagged behind NH peers in all the three tests, and performances on segmental, suprasegmental and sentence-level processing were differentially modulated by implantation age. Furthermore, performances on recognition of consonants and lexical tones were significant predictors of sentence repetition accuracy in the children with CIs. CONCLUSION Overall, segmental and suprasegmental perception as well as sentence-level processing is impaired in Mandarin-speaking children with CIs compared with age-matched children with NH. In children with CIs recognition of segmental and suprasegmental phonemes at the lower level predicts sentence repetition accuracy at the higher level. More importantly, implantation age plays an important role in the development of phonological skills and higher-order language skills, suggesting that age-appropriate aural rehabilitation and speech intervention programs need to be developed in order to better help CI users who receive CIs at different ages.

Abstract
OBJECTIVES To investigate the possible association between the etiology of hearing impairment (HI) and language outcome in children with congenital HI after an early medical-technical intervention and three years of AVT. METHODS A retrospective, two-center study was conducted of 53 patients who were divided in four categories of etiology (degeneratio labyrinthi acustici (DLA) congenita hereditaria, DLA congenita non specificata, DLA congenita postinfectiosa and auditory neuropathy). Language outcome was assessed by examining receptive vocabulary (Peabody Picture Vocabulary Test, PPVT-4), receptive language (Reynell test) and productive language (the Danish 'Viborgmaterialet'). All tests were conducted 1, 2 and 3 years after the children received their hearing device. Test scores were calculated from the child's chronological age. Analysis of possible associations was performed using Fisher's exact test and McNemar's test was conducted to examine possible differences between each year of testing for every speech-language test. Subsequently, univariate analyses were performed to search for other possible covariates associated with language outcome. RESULTS No significant associations were found between the etiology of the HI and the language outcome of children with HI after 1 year of AVT (PPVT, p = 0,234; Reynell, p = 0,845; Viborgmaterialet, p = 0,667), neither after 2 years of AVT (PPVT, p = 0,228; Reynell, p = 0,172; Viborgmaterialet, p = 0,659) nor after 3 years of AVT (PPVT, p = 0,102; Reynell, p = 0,512 Viborgmaterialet, p = 0,580). Some significant associations were found between language outcome and the type of hearing device and between language outcome and additional disabilities, however no strong evidence was found. CONCLUSION Most children with congenital HI developed a comparable level of speech and language regardless of the etiology of their HI. This study highlights the interest of further research using objective assessments techniques in a larger and more homogeneous population. If the findings from this study will be confirmed in future studies, this will have a clinical and societal impact regarding the diagnostics of HI.

Abstract
OBJECTIVES This study compared the auditory reasoning skills of school-going children with early and late cochlear implantation and assessed the relationship between auditory reasoning skills, language development, vocabulary knowledge, and communication skills. MATERIALS AND METHODS In this case series study, 90 pre-lingually deaf children aged 7-10 years were assessed. Children were divided into two groups: early-implanted group with children who received cochlear implants before 3 years of age (mean, 23.45; 12-35 months) and late-implanted group with children implanted after 3 years of age (mean, 50.54; 36-84 months). Tests were performed in the auditory-visual condition. Correlational analyses were used to assess the relationships between daily communication skills, language development performances, vocabulary knowledge, and auditory reasoning skills of both the groups. RESULTS Auditory reasoning skills were better in the early-implanted group than in the late-implanted group (Mann-Whitney U test=518, p<0.05). Language performances of the early-implanted group were significantly better than those of the late-implanted group (receptive language performances: Mann-Whitney U=522, p<0.05; expressive language performances: Mann-Whitney U=552, p<0.05). Stepwise regression analysis showed that expressive language performances, vocabulary knowledge, and chronological age could predict 82% of the variance. CONCLUSION Reasoning skills of children with cochlear implants should be supported during the language-learning process.

Abstract
RESUMO Objetivo: verificar a aquisição de vocabulário em crianças surdas, usuárias de implante coclear, bem como os fatores que influenciam esse desenvolvimento. Métodos: foi aplicada a parte de vocabulário do teste de linguagem infantil ABFW em 20 crianças usuárias de implante coclear por no mínimo três anos. Além disso, foi avaliada a participação familiar no desenvolvimento dessas crianças. Resultados: foi observado que as crianças implantadas apresentam possibilidade de alcançar o desenvolvimento normal de vocabulário, quando comparadas às crianças ouvintes, a depender de diversos fatores. O fator que apresentou influência estatisticamente significante no vocabulário foi a participação familiar, sendo que quanto maior o envolvimento da família no processo terapêutico, melhores os resultados no teste de vocabulário. Conclusão: as crianças implantadas podem apresentar desempenho similar às crianças ouvintes no teste de vocabulário, a depender das variáveis que transcendem a idade à implantação ou mesmo o tempo de uso do implante coclear. A estimulação/ participação familiar no desenvolvimento das crianças se mostrou de extrema importância no desenvolvimento da linguagem oral.

Abstract
PURPOSE We describe the natural auditory environment of people with cochlear implants (CIs), how it changes across the life span, and how it varies between individuals. METHOD We performed a retrospective cross-sectional analysis of Cochlear Nucleus 6 CI sound-processor data logs. The logs were obtained from 1,501 people with CIs (ages 0-96 years). They covered over 2.4 million hr of implant use and indicated how much time the CI users had spent in various acoustical environments. We investigated exposure to spoken language, noise, music, and quiet, and analyzed variation between age groups, users, and countries. RESULTS CI users spent a substantial part of their daily life in noisy environments. As a consequence, most speech was presented in background noise. We found significant differences between age groups for all auditory scenes. Yet even within the same age group and country, variability between individuals was substantial. CONCLUSIONS Regardless of their age, people with CIs face challenging acoustical environments in their daily life. Our results underline the importance of supporting them with assistive listening technology. Moreover, we found large differences between individuals' auditory diets that might contribute to differences in rehabilitation outcomes. Their causes and effects should be investigated further.

Abstract
Cochlear Implantation is now regarded as the most successful medical technology. It carries promises to provide deaf/hearing impaired individuals with a technological sense of hearing and an access to participate on a more equal level in social life. In this article, we explore the adoption of cochlear implantations among Danish users in order to shed more light on their social and political implications. We situate cochlear implantation in a framework of new life science advances, politics, and user experiences. Analytically, we draw upon the notion of social imaginary and explore the social dimension of life science through a notion of public politics adopted from the political theory of John Dewey. We show how cochlear implantation engages different social imaginaries on the collective and individual levels and we suggest that users share an imaginary of being "wired to freedom" that involves new access to social life, continuous communicative challenges, common practices, and experiences. In looking at their lives as "wired to freedom," we hope to promote a wider spectrum of civic participation in the benefit of future life science developments within and beyond the field of Cochlear Implantation. As our empirical observations are largely based in the Scandinavian countries (notably Denmark), we also provide some reflections on the character of the technology-friendly Scandinavian welfare states and the unintended consequences that may follow in the wake of rapid technology implementation of life science in society.

Abstract
CONTEXT Permanent hearing loss affects 1 to 3 per 1000 children and interferes with typical communication development. Early detection through newborn hearing screening and hearing technology provide most children with the option of spoken language acquisition. However, no consensus exists on optimal interventions for spoken language development. OBJECTIVE To conduct a systematic review of the effectiveness of early sign and oral language intervention compared with oral language intervention only for children with permanent hearing loss. DATA SOURCES An a priori protocol was developed. Electronic databases (eg, Medline, Embase, CINAHL) from 1995 to June 2013 and gray literature sources were searched. Studies in English and French were included. STUDY SELECTION Two reviewers screened potentially relevant articles. DATA EXTRACTION Outcomes of interest were measures of auditory, vocabulary, language, and speech production skills. All data collection and risk of bias assessments were completed and then verified by a second person. Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) was used to judge the strength of evidence. RESULTS Eleven cohort studies met inclusion criteria, of which 8 included only children with severe to profound hearing loss with cochlear implants. Language development was the most frequently reported outcome. Other reported outcomes included speech and speech perception. LIMITATIONS Several measures and metrics were reported across studies, and descriptions of interventions were sometimes unclear. CONCLUSIONS Very limited, and hence insufficient, high-quality evidence exists to determine whether sign language in combination with oral language is more effective than oral language therapy alone. More research is needed to supplement the evidence base.

Abstract
OBJECTIVES The objectives of this study were: (1) to investigate the effect of age at cochlear implantation (CI) on vocabulary development; (2) to evaluate the age effect at CI surgery on the syntactic development; and (3) to examine the role of gender, age at first diagnosis and maternal education level on spoken language development. MATERIAL AND METHODS Retrospective study. Thirty children with congenital severe- to -profound sensorineural hearing loss (SNHL) were sampled. They were diagnosed and fitted with hearing aids through six months of age. They were implanted between 8 and 17 months of age. The MacArthur-Bates Communicative Development Inventory (MCDI) was administrated at the age of 36 months. The total productive vocabulary (word number raw score), the mean length of utterance (M3L) and the sentences complexity were analysed. RESULTS The average word number raw score was 566.3 for the children implanted before 12 months of age versus 355 for those implanted later. The M3L was 8.3 for those implanted under 1 year versus 4.2 of those implanted later. The average sentences complexity was 82.3% for those receiving CI before 12 months, while it was 24.4% for those underwent at CI after 12 months. Regression analysis revealed a highly significant and negative linear effect of age at CI surgery on all outcomes. Females had better outcomes. Age at diagnosis was not correlated with the linguistic results. The mother's education level had a positive significant effect on sentences complexity. CONCLUSION The CI in pre-school children with SNHL implanted under 1 year has a positive effect on spoken language. Females seem to have better linguistic results. Finally high maternal educational level appears to have some positive effect on language development.

Abstract
Cochlear implants have a significant positive effect on spoken language development in severely hearing impaired children. Previous work in this population has focused mostly on the emergence of early-developing language skills, such as vocabulary. The current study aims at comparing narratives, which are more complex and later-developing spoken language skills, of a contemporary group of profoundly deaf school-aged children using cochlear implants (n=66, median age=8 years 3 months) with matched normal hearing peers. Results show that children with cochlear implants demonstrate good results on quantity and coherence of the utterances, but problematic outcomes on quality, content and efficiency of retold stories. However, for a subgroup (n=20, median age=8 years 1 month) of deaf children without additional disabilities who receive cochlear implantation before the age of 2 years, use two implants, and are raised with one spoken language, age-adequate spoken narrative skills at school-age are feasible. This is the first study to set the goals regarding spoken narrative skills for deaf children using cochlear implants.
