Otitis media with effusion (OME) is a condition of uncertain aetiology seen in paediatric practice. It has important sequelae that can result in significant morbidity. Worldwide documentation of OME prevalence in older children is poor as OME is traditionally seen in children below the age of 6 years. Available research in Nepal reports a prevalence of OME in children between the ages of 3 and 8 years as high as 27%. This study aims to establish a reliable prevalence of OME in children between the ages of 9 and 16 years in order to inform public health policy and target limited resources.
