We used the Acoustic Otoscope in patients with otitis media with effusion (OME), tubal stenosis, chronic otitis media with large perforation, and obstruction of the ear canal with cerumen in order to evaluate its ability to assess these middle ear conditions. Tympanograms were performed to confirm the diagnosis of these diseases. The diagnosis of OME obtained by Acoustic Otoscope showed a high degree of false negativity in comparison with the diagnosis obtained by tympanography, especially when there was a fluid level. Chronic otitis media with large perforation and obstruction of the ear canal with cerumen also showed considerable false negative results. It is impossible to diagnose tubal stenosis with the Acoustic Otoscope.
