Auditory neuropathy spectrum disorder (ANSD) is a term to describe the auditory characteristics of patients who exhibit normal outer hair cell function and aberrant or disordered neural conduction in other sites along the auditory pathway. The management of children with ANSD is a controversial topic. It is the intention of this study, to investigate the effects of the cochlear implant on the auditory skills of these children. In a cross-sectional analytic study, eight cochlear implanted children with ANSD and eight implanted children with profound sensory-neural hearing loss (SNHL) were selected to participate in this study, with an age ranging between 4.4 to 7.2 years of age and 4.5 to 7.2 years of age, respectively. There was a significant correlation between the age of the hearing loss diagnosed group and the score levels in the auditory skill cases (P=0.012) and the control-groups (P=0.011). All children had a delayed response as compared to the normal hearing children in the investigated skill levels, while no significant differences were noted in the cochlear implanted children with and without ANSD (P=0.877). There were no significant dissimilarities among the auditory skills of the children with ANSD and their matches which indicate that the cochlear implantation results in the synchronous neural activity provided a coherent electrical stimulation; therefore, the hearing function will be improved.

Aural rehabilitation program after a cochlear implant leads to improve the auditory performance of hearing impaired children. The present study aims to determine the effect of cochlear implants and aural rehabilitation program in the auditory development of children with cochlear implants (CI). This longitudinal analytical study was conducted on 15 deaf children (m. a. 45. 27 mo) who received CI in the AmirAlam cochlear implant center between August 2010 and January 2011. Auditory skills of deaf children were assessed before they received CI، and then again 2، 4، 6 and 8 months after implantation. Data was collected by interview with parents of deaf children. Newsha developmental scale is used for this purpose. After determining the developmental age، Pretest Developmental Rate، Intervention Efficiency Index and Proportional Change Index were calculated. One-way ANOVA and LSD post hoc tests were used for analysis of data. There was a significant increase in Pretest Developmental Rate during the aural rehabilitation after a cochlear implantation (p<0. 0001). There was a significant difference among the 4 follow up assessments of Intervention Efficiency Index (P<0. 0001). There was also a significant difference among the 4 follow up assessments of proportional change index (P<0. 0001). Aural rehabilitation program after a cochlear implant can accelerate the development of auditory skills of children with cochlear implants، which in turn results in acquire skills close to normal hearing peers.

Evaluation of hearing-impaired children's auditory skills by a valid test is very important before starting auditory training. There are many different tests available for languages other than Persian, and some limited Persian tests for children above 5 year of age as well. Accordingly considering the importance of early intervention, we aimed to design a test for evaluating auditory skills of 3-4 year-old hearing-impaired Persian (Farsi) children, which is not available to date. The study method was test (scale) construction. The test named Tavana includes four subtests: detection, discrimination, identification and sentence comprehension. For determining content validity of the test, the vocabulary of 3-4 year-old normal-hearing and hearing-impaired children and also the comments of seven specialists were applied. We classified 10,10,8 and 6 sub skills for 1st to 4th subtests, respectively. The content validity of Tavana test's subskills were 100%, 83%, 96% and 95%, respectively (mean=94%). Mean time for test performance was 82 minutes. Content validity of Tavana test was 94% which was statistically valid compared to Modarres test (97%) and Mazaheryazdi test (88%).
