Abstrakt:	Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction involving nasal mucosa characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness, and eyes itching. Tympanometry is a simple, rapid, and objective test that can be easily carried out. The use of tympanometry in clinical setting can improve detection of middle ear effusion and other middle ear abnormalities. AR has been found to be one of the predisposing factors to developing Otitis Media with Effusion (OME) in children. Patients and Methods: A case-control study was used to determine the prevalence of OME among children with AR as cases and those without allergy as controls. The study participants were children aged 4-12 years with clinical diagnosis of AR attending ENT clinics of Aminu Kano Teaching Hospital, whereas controls were children age 4-12 years without history of AR, ear diseases, or other respiratory system related ailments attending general outpatient clinics in Aminu Kano Teaching Hospital. An interviewer-administered score for AR (SFAR) questionnaire was filled out for all the participants, those with score of 6 and above were selected as cases. The two groups had complete ENT examination and tympanometry done, findings were recorded, and analyzed using SPSS version 21. Results: The mean age of the cases was 6.8 ± 2.1 years, whereas it was 7.5 ± 2.6 years for the controls. The mean difference was 0.7 and was not statistically significant (t = 2.35, df = 258, P value = 0.20). Type B tympanogram suggesting OME was found in 7.3% of subjects and in 2.8% of controls. Type C tympanogram suggesting negative middle ear pressure was found in 15.5% of subjects and in 4.6% of controls. Type A tympanogram suggesting normal middle ear pressure was found in 75% of subjects and in 90% of controls. Acoustic reflex was found to be absent in 29.6% of subjects and in 15.4% of controls and this found to be statistically significant (χ 2 = 7.77, df = 1, P value = 0.001). The difference between type A, B, and C tympanograms of subjects and that of controls was found to be statistically significant (Type A χ 2 = 14.62, df = 4, P value = 0.01, Type B χ 2 = 14.06, df = 4, P value = 0.01, Type C χ 2 = 17.01, df = 6, P value = 0.01). Type B tympanogram was used as an indicator to suggest OME for the purpose of this study. Conclusion: Participants with AR were found to have more abnormalities of tympanometric parameters and higher prevalence of type B tympanogram suggesting OME than controls. Competing Interests: None
