Objective: The aim of this study was to investigate the role of tympanogram test in routine use comparing the tympanogram findings and otoscopic examination find- ings in patients with suspicious otitis media with effusion. Materials and methods: 64 outpatients with suspicious otitis media with effusion presented at our Otorhinolar- yngology clinic and first otoscopic examination and then tympanometric examination was performed for their 128 ears. Predictions of the physicians who performed oto- scopic examination for outcomes from tympanogram and actual tympanogram outcomes were compared. Results: Predictions of the physician for otoscopic ex- amination were different from tympanogram outcomes in 22.6 percent (n=29) of 128 otoscopic examinations in total. However, the physician predicted Type A tym- panogram suggesting no effusion in only four of these otoscopic examinations yet Type B or Type C outcomes suggesting existence of effusion were obtained from tym- panogram. Conclusion: Application of tympanogram test routinely as part of otologic examination to each patient is a cause of material loss. Our first choice should be otoscopic ex- amination.
