ABSTRACT: The aim of our study is to present the results of 11 children where auditory brainstem implantation (ABI) was successfully performed to restore hearing. Case presentation. This study was conducted at the departments of Otolaryngology and Neurosurgery at Hacettepe University Ankara, Turkey. Between July 2006 and April 2008, 11 prelingual (30-56 mo) deaf children with several cochlear malformations had ABI. All patients were programmed and were enrolled in auditory verbal therapy sessions and family counseling programs at Hacettepe Auditory Verbal Center. The evaluation was performed at preimplant and again 1, 3, 6, 9, and 12 months post-switch on. The main test components composing this test battery were Ling 6 Sound Detection-Identification Test, Word Identification Test in Turkish, Meaningful Auditory Integration Scale, and Meaningful Use of Speech Scale. Successful brainstem implantations were performed in all patients with retrosigmoid approach. Six children gained basic audiologic functions and were able to recognize and discriminate sounds, and many could identify environmental sounds such as a doorbell and telephone ring by the third month of ABI. Improvement in mean performance on Meaningful Auditory Integration Scale is apparent for all ABI children. Improvement in Meaningful Use of Speech Scale scores in 2 patients, demonstrating that the child using its own voice for speech performance, was observed between the baseline and 12th month. First, 5 children were able to identify Ling's 6 sound by the end of 2 to 6 months, and 2 of them also started to identify words due to their pattern differences and multisyllabic word identification by 6 to 9 months. Two children with Attention Deficit Hyperactivity Disorder have made slower progress than the other children with ABIs. Our preliminary results show that there is adequate contribution of brainstem implants in the development of auditory-verbal skills. Additional handicaps slow the progress of the prelingually deaf children.Otology & neurotology: official publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology 10/2009; 30(6):708-15. · 1.44 Impact Factor -
Article: The needs of hearing impaired children's parents who attend to auditory verbal therapy-counseling program.
[show abstract] [hide abstract]
ABSTRACT: Exploring the information and support needs of parents with hearing impairment in habilitation process. The effects of variables such as duration of hearing aid use and habilitation (duration of intervention) and the number of hearing impaired individuals in family are also considered during the evaluation. Sixty-five parents of children between 24 and 348 months of age (median: 80) participated in this study by returning the completed in The Family Needs Survey. Age at diagnosis of deafness varied from 1 to 84 months of age (median: 16). The duration of hearing aid use was 8-252 months (median: 24) and the duration of intervention was 2-176 months (median: 36). In view of the fact that the family dynamics might have effects on the type and amount of the needs of parents, the number of siblings (none, two or more siblings) and the presence of hearing impaired individuals apart from their child was also explored. The parental needs with regard to different topics such as general information, hearing loss, communication-services and educational resources, family and social support, childcare and community services, financial were evaluated separately. The needs of parents participating in a multi-dimensional Auditory-Verbal intervention program differed by their preferential demands. The duration of intervention was found significantly correlated with the amount of information needs related with other conditions their children may have, explaining their children's hearing problem to others, locating good baby-sitters and day-care programs for their children and transportation (p< or =0.05). It was also found that the long-termed continuing intervention generates additional psychotherapeutic, social and financial needs for the parents. No significant correlation was found between hearing impaired individuals existence with the type and amount of family needs (p>0.05). These findings support the positive effect of persistent and long-term Auditory-Verbal therapy and Counseling approach which incorporates parents as inalienable members in all rehabilitation process. Creating an adequate and appropriate educational environment by considering individualized needs and family dynamics in a long term and persistent Auditory-Verbal therapy and Counseling approach are all equally important. In addition to a team approach to management, with parents taking a major role in the habilitation process, and all these will lead to a much better outcome.International Journal of Pediatric Otorhinolaryngology 07/2008; 72(7):1097-111. · 1.17 Impact Factor -
Article: The effect of implantation age on visual attention skills.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study is to evaluate the visual attention skills of deaf children with cochlear implants and to determine whether age at implantation had any impact on visual attention skills. Thirty children with cochlear implants aged 6 and 11 years were evaluated and were compared with age matched 36 normal hearing children. The children with cochlear implants were analyzed in to two groups according to their age at implantation; under and at/over 4 years old. The Gordon Diagnostic System (GDS) was used in order to evaluate visual attention skills of cochlear implanted (Group 1 and Group 2) and children with normal hearing. The number of correct responses, extraneous button presses (commission errors) and the number of omission errors or the failure to respond to target stimuli which were recorded by GDS was used to evaluate the visual attention skills of the subjects. Also six different types of commission errors (19X, XX9, XX1, X1X, X9X, XXX) were analyzed and compared both for normal and cochlear implant user children. Concerning the total number of correct response, omission and commission errors no statistical difference was found between two implanted groups. Besides, both groups with cochlear implantation differed from normal hearing peers on the total number of correct responses, omission errors (p<0.017). According to these findings cochlear implanted children had less correct responses and had more omission errors compared with control group. These findings clearly show that children with cochlear implants performed poorly on visual attention task which requires constant attention together with the ability to exert impulse control despite they hear enhanced sensory information by cochlear implants. Concerning the types of commission errors Group 1 and 2 performed similarly in all types of errors (p>0.017). Besides, Group 1 and 2 made more errors in types 19X, XX9 and XXX, XX9 compared with the control group (p<0.017). Group 2 who had their implants after age of 4 years old had more commission errors than the control group (p<0.017) and positive correlation was found between the total commission errors and XX9 error type with age at implantation. These findings show that children who had their implants at older ages made more commission errors and XX9 type of commission error. The children who were implanted after 4 years old were less mature; unsuccessful in controlling their impulsive behaviors and more careless where they can not get enough benefit from social and environmental motives compared with their normal hearing peers. This present research points out the positive effect of early implantation on visual attention and the possible adversities such as impulsivity, over-impatience and attention deficits which have been previously suggested as preventive or slowing down factors for the pace of auditory-verbal therapy for cochlear implantees. Assuming that the results of this study support the theory of insufficiency which suggested that the deprivation in auditory system would also adversely affect cognitive structures involved in intermodal processing the importance of early implantation is underlined. If early cochlear implantation will be carried out especially at the very critical period of language development (before age of four), this will help the child, in his/her future life, not only with his/her hearing skills and communication but for his/her attention skills and behavior.International Journal of Pediatric Otorhinolaryngology 06/2008; 72(6):869-77. · 1.17 Impact Factor -
Article: Is psychological status a determinant of speech perception outcomes in highly selected good adolescent cochlear implant users?
[show abstract] [hide abstract]
ABSTRACT: The main purpose of this study was to assess the relationship between the speech perception skills and state-trait anxiety in cochlear implant user adolescents who were highly selected good candidates. The impact of preoperative speech perception ability on postoperative speech perception and state-trait anxiety status were also examined. The subjects for this study were 25 consecutively chosen congenitally profoundly deaf adolescents (12 boys, 13 girls) who received nucleus multi channel cochlear implants and were followed for at least a year at Hacettepe University. Daily Sentences in Turkish and State-Trait Anxiety Inventories (STAI) were administered to subjects after 12-72 months (mean: 35.28+/-18.27) of implant use. The trait and state anxiety scores were matched with the relative rank of normal hearing subjects' trait-state anxiety scores and the analysis of post-implant state-trait anxiety findings shows that both state and trait anxiety scores were widespread but still in normal range. The correlation between trait, state anxiety scores and speech perception ability was not statistically significant in adolescent cochlear implant users. However, their preoperative speech perception scores were significantly correlated with their postoperative speech perception abilities. The majority of adolescents, in this study, achieved varying degrees of open-set speech recognition and made greater gains than their previous auditory experience with hearing aids. Also, the indirect positive effects of early identification-amplification, communication therapy and counseling programs on their personal well-being is clearly observed from the outcomes of their state and trait anxiety scores. As a result of correlating the trait and state anxiety levels with pre- and post-implant speech perception skills, a significant negative correlation was expected. However, no statistical correlation was found between speech perception skills and the psychological outcomes. This result may be the indicator of the positive effect of the early habilitation-parental support and cochlear implant on the quality of life as the adolescents involved in this study were developmentally and audiologically ready for implantation. The present study provides understanding of the audiological and social-emotional influences of early identification and habilitation programs on adolescents with cochlear implants.International Journal of Pediatric Otorhinolaryngology 10/2007; 71(9):1415-22. · 1.17 Impact Factor
