Ages of hearing loss diagnosis and cochlear implantation in hearing impaired children
Audiology, 2012
Background and Aim: Early diagnosis of hearing loss lead to early intervention and improvement of developmental skills of children with hearing loss. The present study aimed to determine the mean age of hearing loss diagnosis and cochlear implantation (CI) in hearing impaired children and to compare the age of performing cochlear implantation in children who were identified by newborn hearing screening with those who were not. Methods: This cross-sectional study was conducted on 96 children with severe to profound sensorineural hearing loss who received cochlear implantation in Amir-e-Alam cochlear implantation center between the years 2008 and 2010. For data gathering, we assessed subjects' medical archives, interviewed with their parents and took medical history including demographic information, birth history and hearing loss history. Results: Mean age of hearing loss suspicion, diagnosis, hearing aids administration, Initiation of rehabilitation program, performing cochlear implantation and mean age when cochlear implantation was utilized were 6.73 (SD=5.79), 9.35 (SD=5.79), 13.41 (SD=6.10), 16 (SD=6.36), 41.25 (SD=11.12), and 42.15 (SD=11.00) months, respectively. There was statistically significant difference between them (p<0.05). 43.8% of hearing impaired children had been identified by newborn hearing screening. There was statistically significant difference between cochlear implantation operation age of children who were identified by newborn hearing screening with those who were not (p<0.0001). Conclusion: In spite of notable reduction in the age of hearing loss diagnosis and intervention during recent years, compared to international indices it is still tardy. Conducting newborn hearing screening can significantly reduce these ages.
A retrospective study of cochlear implant outcomes in children with residual hearing
BMC ear, nose, and throat disorders, 2006
There has been increasing demand for the cochlear implantation of children who demonstrate some auditory capacity with conventional hearing aids. The purpose of this study was to examine speech recognition outcomes in a group of children who were regarded as borderline candidates for cochlear implantation as their residual hearing and/or auditory functioning levels exceeded typical audiologic candidacy criteria. A retrospective chart review was undertaken at one Canadian cochlear implant centre to identify children implanted at age 4 or older with a pure-tone-average of 90 dB or better and speech recognition of 30% or greater. Pre-implant and post-implant open-set word and sentence test scores were analyzed. Eleven children of 195 paediatric cochlear implant recipients met the inclusion criteria for this study. Speech recognition results for the 10 English-speaking children indicated significant gains in both open-set word and sentence understanding within the first 6 to 12 months o...

Background and Objective: Age of cochlear implantation (CI) is an important factor for restoring normal auditory processing and different language skills so that early diagnosis of hearing loss significantly influences the rate of developmental skills in these children. The present study aimed to investigate different factors affecting the age of hearing loss diagnosis and CI in children with hearing loss. Methods: This was a descriptive cross-sectional trial conducted on the children with hearing loss that underwent CI (n=252) in the Khuzestan Cochlear Implant center, Ahvaz, Iran during 2012 to 2015. The demographic data of children and parents, age of diagnosis, application of hearing aid, and rehabilitation therapy were collected through a questionnaire during the regular visits of the patients. The data were analyzed using statistical package SPSS (Windows, version 18).The normality of data and homogeneity of variances were evaluated through Kolmogorov-Smirnov and Leven tests, respectively. Then, T-test was used to evaluate the statistically significance of the difference and Pearson correlation coefficient to determine the relationship between the quantitative variables. Results: The mean age of diagnosis was 10.7 months (range 0.1 to 60 months). Of 252 patients, 131 (52%) were male and 121 (48%) were female (p=0.98) and 123 patients (50.2%) had a positive family history of hearing loss or deafness (p<0.0001). In addition, 17 patients (6.9%) had a favorable economic status, while 96 (38.9%) had a moderate and 134 (53.2%) a low economic status. Interestingly, 78.8% of the deaf children were from parents of consanguineous marriages, and 12.2% from non-consanguineous unions. Of the six studied variables, only family history and family relationship variables showed significant relationship with age of diagnosis of hearing loss. Conclusion: Providing comprehensive basic information and increased awareness may help all parents, even those with low socioeconomic status and educational level, to detect hearing loss in their newborns as early as possible. This approach could prevent the consequent adverse effects of hearing loss on psychological, social, and social dimensions as well as on educational achievement in childhood.
Variations in Gains in Auditory Performance from Pediatric Cochlear Implantation
Otology & Neurotology, 2002
To investigate variations in gains in auditory performance in children with cochlear implants. Study Design: The auditory performance of 98 children was measured with the Category of Auditory Performance survey instrument. All data were collected prospectively. Variables used to explain gain in Category of Auditory Performance were age at implantation, sex, the duration of "untreated" deafness, the year in which implantation occurred, health care inputs, and cause of hearing impairment. The data were analyzed by ordered probabilistic regression analysis. Results: Gain in Category of Auditory Performance was observed to be negatively related to age at implantation, the year in which implantation took place, and the number of medical consultations the child received. None of the other variables were significant determinants of gain in Category of Auditory Performance. Conclusion: This study demonstrates the value of examining incremental gain from implantation rather than simply examining outcome levels. It was found that pediatric implantation is subject to diminishing returns. This suggests that further relaxation of entry criteria to implant programs should be undertaken only after careful consideration. The study also confirmed that age at implantation is an important determinant of outcomes. Greater gain in Category of Auditory Performance was experienced by those who underwent implantation at a younger age. This finding has implications for screening, as well as for purchasers and providers of implant services, highlighting the importance of responding in a timely fashion to identified need.
Outcome of Cochlear Implantation at Different Ages from 0 to 6 Years
Otology & Neurotology, 2002
To evaluate the outcome of cochlear implantation in young children in relation to the age at implantation. Study Design: A retrospective longitudinal and cross-sectional analysis of pediatric cochlear implant patients. Patients: All children with congenital deafness who underwent implantation before the age of 6 years (n ס 48 for the longitudinal analysis and n ס 70 for the cross-sectional analysis) Interventions: All children received a multichannel cochlear implant. Main Outcome Measures: Categories of Auditory Performance (CAP) score and integration into the mainstream school system. Results: For all children, the CAP score increased after implantation. Implantation beyond the age of 4 years hardly ever resulted in normal CAP scores or in integration into the mainstream primary school (20 to 30% of cases). Implantation between the age of 2 and 4 years always resulted in normal CAP scores after 3 years with a 66% probability of integration into the primary school. Implantation before the age of 2 years always resulted in immediate normalization of the CAP scores, with a 90% probability of integration into the mainstream kindergarten, well before entrance into the primary school.

To compare the auditory abilities and speech performance of children with a profound prelingual bilateral hearing-impairment when subjected to a cochlear implant (CI) before or after 2 years of age. To analyze the complications that arose during, or as a result of, the implantation process in these groups. Design: Prospective cohort single-subject, repeatedmeasures study of children with profound bilateral hearing impairment subjected to CI. Setting: Tertiary referral center with a program of pediatric CI from 1991. Patients: This study analyzed 130 children subjected to multichannel CI for profound prelingual bilateral hearing-impairment in two age groups: 0 to 2 (n ؍ 36) and 2 to 6 years of age (n ؍ 94). Interventions: The children were evaluated before, and each year after, the intervention (for up to 5 years) with both closed-set and open-set auditory and speech perception tests. Their speech ability was evaluated according to the Peabody Picture Vocabulary and Reynell general oral expression scales. Results: Auditory and speech perception tests improved significantly in all children after CI, regardless of the follow-up time. The infant's performance was better the earlier the implant was performed. Speech tests showed that the development of children treated before 2 years of age was similar to normal children, and no additional complications were observed when compared with CI in older children. Conclusions: When performed before 2 years of age, CI offers a quicker and better improvement of performance without augmenting the complications associated with such an intervention. Key Words: Cochlear implantation, hearing impairment, inner ear surgery, speech development, treatment outcome, early implantation.
Delayed Cochlear Implantation in Children: A Parental Survey
The Scientific Journal of University of Benghazi, 2022
Background: Untreated childhood hearing loss can adversely affect speech and language development as well as academic, social, emotional, and behavioral development. Early cochlear implantation before the age of 4 years, within the critical period for central auditory development, was found to be crucial in reducing the negative impact of auditory deprivation and appears to provide better outcomes than late implantation. aim: The aim of this study was to determine the reasons behind late cochlear implantation in children with congenital severe to profound sensorineural hearing loss. Methods: A retrospective study was conducted on all cases who received cochlear implants at Specialty Surgical Center, Benghazi, Libya between October 2017 and June 2021. Patients' medical records were reviewed and demographic and clinical data were collected. Children with other disabilities, and post-lingual and post-meningitis implantees were excluded from the study. Information about the reasons for the delay in receiving cochlear implants was obtained over the phone from parents whose children underwent cochlear implant surgery beyond the age of 4 years. Results: A total of 74 children were included, 38 boys and 36 girls. The mean age at implantation was 47 months. Forty-one percent (41%) of children were implanted after 4 years of age. Two-thirds of these children live outside Benghazi. Most of the children had at least one risk factor for hearing loss. The majority of parents reported more than one reason for the delayed implantation. Conclusion: It is found that parent decision-making for cochlear implantation is difficult and affected by many factors, including their personal beliefs (denial, social stigma and fear of surgery), lack of awareness about the existence of cochlear implant technology, and financial constraints. It is recommended that a national newborn hearing screening program is established for early detection and intervention and cost-effectiveness.
