The neonatal department of our hospitals have a programme of universal newborn hearing screening, on the basis of which all babies have their hearing tested prior to discharge. We recommend that your baby has his/her hearing tested.
Good hearing is important for your child to learn speech and language. Because a hearing loss can prevent your baby from learning speech and language, it is important to diagnose hearing problems early, which is why we recommend your baby's hearing to be tested.
The purpose of newborn screening is to identify children who are at greater riskfor hearing loss so that they may receive timely diagnostic and interventionservices. Hearing screenings are NOT diagnostic evaluations. Screening testsidentify a need for further diagnostic hearing evaluations.
Approximately 3 in 1000 babies are born with a hearing loss. 1 in 1000 babies are born deaf. 90% of children with hearing loss are born to hearing parents. Some babies may be at a higher risk of developing a hearing loss. Theearlier that the hearing loss is identified, the sooner that intervention may begin.
Hearing can be assessed at any age, even the day that a child is born. Brainstem Evoked Response Audiometery (BERA) and Evoked OtoacousticEmissions (EOAE) evaluations are an effective and efficient means foridentifying and quantifying hearing loss. Both tests are effective for newbornhearing screening.
The hearing test will be primarily carried out using EAOE. The EOAE evaluation is performed by placing a small earphone into the child's ear. Clicking sounds are introduced into the child's ear. Echo responses, or emissions, are measured in healthy ears. EOAEs are acoustic signals generated by the cochlea, specifically, outer hair cells, in response to auditory stimulation. In response to click stimuli, EOAEs provide information over a broad frequency range (~500-6000Hz). Present EOAEs indicate that a child has normal/near normal hearing.
At the end of the test you will be given a report of the outcome, as well as a "Hearing Checklist' which allows you to monitor the Hearing Milestones of your baby.
If the EOAE screen is not conclusive, the child is 'referred' for the Hearing Screen to be repeated. This must be done within 30 days. If the second EOAE screen is also not conclusive, the baby is 'referred' for further definitive hearing tests using a battery of detailed hearing tests. A referral does not necessarily mean that the baby has a hearing loss, but suggests that the test was inconclusive and further testing is indicated. The Comprehensive Hearing Assessment (CHA) battery includes these tests: ABR., ASSR, OAE, Impedence, BOA. This should ideally be carried out before the baby is 3 months of age.
My experience with cochlear implant My name is Gerald Andrew; I am 29 year old male Tanzanian. Last year (2009) was one of the most memorable for me. It’s when I received my cochlear implant at Apollo hospital in New Delhi after Read More »
I wanted to thank you immensely for the help that you provided to my father and thus to our family by giving him the gift of hearing. He is now recovering well and is able to hear all the conversations as normally as anyone else can.
My father, underwent a Stapedotomy ear surgery to correc ct his hearing problem, first in one ear and then 6 months later in the other. The result of the surgery was better than expected and post full recovery my father is able to hear very well. Read More »
My experience with cochlear implant My name is Gerald Andrew; I am 29 year old male Tanzanian. Last year (2009) was one of the most memorable for me. It’s when I received my cochlear implant at Apollo hospital in New Delhi after more than three years of hearing loss. Everyone’s experience with coch hlear implant is a bit different therefore, am happy to share mine with anybody out there, from the moment I lost my hearing, my experience during my stay at Apollo Hospital and one year later on, after cochlear implant.
