Hearing impairment in preschool children is an important developmental disability, we conducted a study on 250 preschool age group children to find out type and cause of hearing impairment amongst them. The commonest type was conductive hearing loss (CHL). Impacted ear wax (18%), otitis media (16%), neonatal jaundice (12.4%), birth asphyxia being the common cause. Type A tympanometry was seen in majority of the patient. Hearing impairment amongst preschool children makes a huge disease burden and a better execution of nation and state level awareness program is needed.
