A prospective cross-sectional study was done to investigate the involvement of @entity2172 in @entity1577 . Eighty-eight @entity1 with @entity1577 , aged 1-28 years, were examined during the winter period 1995-1996 at regular follow-up visits to detect history and prevalence of inflammatory and infectious @entity2172 by questionnaire, otoscopy and tympanometry. One third of the @entity1 had a history of @entity2346 media, but only in 9% did this occur more than once. Hearing problems were recorded in 8%, but this was severe in only one case. Otoscopy showed 141 normal tympanic membranes, 17 times retraction, 15 times @entity2346 media with effusion, once an @entity697 media in both ears. Only one @entity1 had a grommet in one ear. More than 70% of the tympanograms were normal. A flat curve, type B according to Jerger's classification, was found in 11 ears. The youngest age group had a higher prevalence of abnormal findings on otoscopy and tympanometry, while @entity1 who had undergone paranasal sinus surgery had less frequently abnormal findings. In conclusion, no evidence that @entity1577 is associated with increased prevalence of @entity2172 has been found in this prospective cross-sectional study.
