Engel, Lucien Anteunis, Mickey Chenault, Edmond Marres] To determine the value of different otoscopic findings in diagnosing otitis media with effusion, 3,780 otological examinations of 250 infants at ages 0-2 years were compared with tympanometric findings. Otoscopy was performed by an experienced otologist and research-audiologist prior to tympanometry. The following success rates for these procedures were found: otoscopy, 85-91%, tympanometry, 74-94%, either otoscopy or tympanometry, 89- 99%. "Glue” was noted as the most frequent abnormal otoscopic feature, i.e., depending on age, 6-32%. Fluid line/ bubbles, bulging/hyperaemia or otorrhoea were rarely (0- 5%) observed and contributed little to the diagnosis of otitis media with effusion. No structural changes of the tympanic membrane were observed. Analysis of tympanometric data revealed that the prevalence of tympanogram types B (21-44%), C1 (0.5-16%) and C2 (0-8%) was age-dependent. Comparison of otoscopic and tympanometric findings indicated sufficient diagnostic agreement (Cohen's kappa between 0.41 and 0.74) at age 6-24 months. In conclusion, otoscopy appears to be a valid instrument for diagnosing otitis media with effusion, at least from 6 to 24 months of age. In addition, the results of our study suggest that tuba-dysfunction and otitis media with effusion are age-dependent disorders during infancy, without structural effects on the tympanic membrane.
