Abstract

The objective of this study is to identify the prevalence of otitis media with eVusion (OME) in primary school children and to value the possible predisposing factors focusing on relationship between allergy and OME in Western Sicily. 2,097 children attending primary school were screened from September 2006 to June 2007 in Sciacca. Children underwent pneumatic otoscopy, skin tests, tympanogram and acoustic reXex tests. Audiogram was performed if the child had a type B or a type C tympanogram. The criteria for diagnosis of OME were: documented persistent middle ear eVusion by otoscopic examination for a minimum of 3 months, presence of B or C tympanogram, absence of ipsilateral acoustic reXex and a conductive hearing loss greater than 25 dB at any one of the frequencies from 250 Hz to 4 kHz. OME was identiWed in 143 children, in 61 of whom OME was unilateral and in 82 of whom it was bilateral. The overall prevalence of OME was 6.8%, with a maximum prevalence of 12.9% between 5 and 6 years of age. By increasing age, the prevalence of OME decreased. Also, we found a higher prevalence rate of OME in children with positive skin tests (62.9%) than those with negative skin tests (37.1%). The present study evidences the high social impact of OME, whose prevalence is directly correlated to age and atopy. Moreover, our Wnding supports the literature data that climatic and environmental factors may also have a role in the occurrence of OME.
