ABSTRACT

Background Otitis media with effusion is the leading cause of hearing loss and language disorders in children, usually secondary to Eustachian tube dysfunction, and it is directly related to allergic rhinitis, one third of patients with recurrent otitis media had allergic rhinitis, considering this, it is necessary to know how often occurs otitis media in children with allergic rhinitis to learn the extent of the problem and thus perform different preventive strategies.
Patients and method An observational, cross-sectional, analytic study of patients aged 2-12 years with a clinical diagnosis of allergic rhinitis with positive skin tests to aeroallergens. Patients with risk factors for otitis media were excluded. We studied the prevalence of otitis media and tube dysfunction by means of tympanometry in patients with allergic rhinitis, compared with a control group without allergic rhinitis. Patients were classified according to the severity of their symptoms within the ARIA classification and prevalence ratios between the two groups were calculated.
Results Nine-two patients, 46 per group, yielded a prevalence of 63% of abnormal tympanometry in allergic rhinitis group against 13% in control group, with a prevalence ratio of 4.83 (95% CI: 2.59-9.03) of abnormal tympanometry in allergic rhinitis patients, compared with control group, p ‹ 0.05; allergic rhinitis patients classified as mild persistent, moderate/severe intermittent and moderate/severe persistent showed a higher prevalence of abnormal tympanometry with p value ‹ 0.05.
Conclusions There is a high percentage of otitis media/tube dysfunction prevalence in patients with allergic rhinitis. It is necessary to perform impedance studies in children with allergic rhinitis to implement preventive strategies.
