Dr. Soumyashree G, Dr. Suprith LK, Dr. Shruthi K, Dr. Abhilash N

Late identification of hearing loss presents a significant public health concern. However, without screening, children with hearing loss are usually not identified until 2 years of age, which results in significant delays in speech, language, social, cognitive and emotional development. Detailed history was taken about the baby and noted. Babies are brought to a noise free room for examination. With babies comfortably ling on mother’s lap, a soft pediatric probe tip is placed in the ear canal to obtain a tight seal. A miniature speaker within the probe assembly generates in the ear canal sound stimuli at a moderate intensity level. Among this population 1244 babies (90%) passed in the first screening, 136(10%) were failed (refer). Out of 136 babies, 6 were unilateral and 130 were bilateral. Of 136 babies 6 babies were lost follow up and second screening test was done for 130 babies. Among them 10 babies (0.7%) failed in the second screening test. Of these 10 babies 4 lost follow up and BERA was done for 6 babies, 5 of them were confirmed to have sensorineural hearing loss.
