Analysis Of Children With Hearing Disorders And Hearing Rehabilitation

"The hearing impairment status analysis and hearing rehabilitationon children" is composed of 3 parts: the sampling survey of hearingimpairment, the analysis of rehabilitation strategy and the new technologyin mapping after cochlear implants in prelingually deafness youngchildren. There are several highlights:1. According to the first-hand database from the China secondsampling disability survey (Jiangsu province) in 2006, the prevalence,grade, and pathogenesis of hearing disability on 0-6 year old childrenwere analysised. The results reflect the new trends on the prevalence anddevelopments of hearing disability in the new era.2. To confirm that automatic auditory brainstem response (AABR)can be used as the first choice in the universal neonatal hearing screening.3. To investigate the rehabilitation demands and strategy of 0-6 yearsold children with hearing disability in Jiangsu province. The results show:(1) The low income families with severe hearing loss children need morespecial policy to help them in expensive medical service such as cochlearimplants. (2) The rehabilitation demands of less than 3 years old childrenand rural areas should be taken into account.4. Under the support from University of Queensland, Australia, triedto develop an appropriate mass screening system to evaluate hearing loss for primary school children, especially in rural areas.5. To investigate the relationship of electrically evoked compoundaction potentials (ECAP) to psychophysical performance. Linearregression analysis showed both the average of T-level and C-level hadgood correlation with ECAP threshold. The linear regression formula is:T=0.83NRT threshold +0.57 (R~2=0.9052, P=0.0128), C=59.83+0.75NRTthreshold (R~2=0.9796, P=0.0103). It is useful in predicting mapping aftercochlear implants on young prelingually deaf children, who could notdemonstrate reliable psychophysical performance.
