SUMMARY 2000 ,Tehran schoolaged children, were included in a randomized trial to evaluate the risk factors for otitis media with effusion through interviews, a written questionnaire, otoscopy pneumatic and tympanometry. We found that the incidence of OME increased in children with parents who smoke (P<0.001) and were bottle fed as babies (P<0.005). Others factor such as, allergy, sinusitis, p...
