Objectives: This study aims to investigate the effects of adenoid hypertrophy on negative middle ear pressure and diagnostic efficiency of tympanogram in the detection of otitis media with effusion in children without parental suspicion of hearing loss. Patients and Methods: Fifty-six children 26 boys, 30 girls; mean age 5.9±2.2 years; range, 3 to 12 years who underwent adenoidectomy were analyzed using otoscopy, nasal endoscopy, and tympanometry before 1 week and 3 months after adenoidectomy . Results: The median negative middle ear pressure before the adenoidectomy was significantly higher from after adenoidectomy p=0.045 . Type B tympanogram were detected in 13 of the 112 ears preoperatively. About 17.9% n=20 of the ears with otitis media with effusion were confirmed by myringotomy. Conclusion: Our study findings suggest that the adenoid hyperthrophy is associated with increased negative pressure in the middle ear. We believe that it is necessary to perform the middle ear examination and tympanometry in children before adenoidectomy and in children without parental suspicion of hearing loss, even.

Amaç: Bu çalışmada adenoid hipertrofisinin orta kulak basıncı üzerine etkisi ve ailesel işitme kaybı şüphesi olmayan çocuklarda, timpanogramın efüzyonlu otitis mediada tanısal etkinliğinin araştırılması amaçlandı.Hastalar ve Yöntemler: Adenoidektomi ameliyatı yapılan 56 çocuk 26 erkek, 30 kız; ort. yaş 5.9±2.2 yıl; dağılım, 3-12 yıl otoskopi, nazal endoskopi ve timpanometre kullanılarak analiz edildi adenoidektomiden 1 hafta önce ve 3 ay sonra .Bulgular: Adenoidektomi öncesi ortalama negatif orta kulak basıncı adenoidektomi sonrasına göre anlamlı derecede yüksekti p=0.045 . Yüz on iki kulağın 13’ünde ameliyat öncesi tip B timpanogram saptandı. Kulakların %17.9’unda n=20 efüzyonlu otitis media miringotomi ile doğrulandı.Sonuç: Çalışma bulgularımız adenoid hipertrofisinin artmış negatif orta kulak basıncı ile ilişkili olduğunu göstermektedir. Çocuklara ve ailede işitme kaybı olmayan çocuklara dahi, adenoidektomi öncesinde orta kulak muayenesi ve timpanometri yapılmasının gerekli olduğu kanısındayız
