Antalya Eğitim ve Araştırma Hastanesi, KBB, Antalya, Türkiye Objective: To investigate the preoperative sensitivity and specificity of binocular microscopy in the diagnosis of otitis media with effusion (OME).

Methods: By reviewing the retrospective findings of preoperative tympanometry, intraoperative binocular microscopy and middle ear fluid features which was aspirated during myringotomy, we evaluated 800 ears in total in 400 children who had myringotomy in our clinic.

Results: The average age of patients was 6.28 (± 2.99) and the ages ranged between ages 1 and 17. Tympanometry sensitivity was 93.6%, specificity was 21.3%, the positive predictive value (PPV) was 73.9% and the negative predictive value (NPV) was found to be 58.1%. Binocular microscopic examination's sensitivity was identified as 94.5%, specificity as 22.6%, PPV as 74.4% and NPV as 63.1%

Conclusions: In our study we found that binocular microscopy is the most specific and sensitive diagnostic tool in the diagnosis of OME. Keywords : Otitis media with effusion, binocular microscopy, tympanometry
