Bone Conduction Changes in Acute Otitis Media

DESCRIPTION OF THE CLINICAL MATERIAL An analysis of the results of bone conduction tests is presented here. The tests were performed on 30 patients. Of this number, 25 patients were affected with purulent perforative otitis media and 5 patients with acute congestive otitis media. Of those with purulent disease, 7 hadtheir first inflammatory aural attack and 23 had an acute exacerbation of chronic purulent otitis media. The 5 patients suffering with acute congestive otitis media all had their first inflammatory aural attack during the period under study. The group represents all consecutive cases of acute purulent and chronic purulent exacerbated otitis media in which satisfactory observations could be obtained. However, it does not represent all such consecutive cases of acute congestive otitis media. Only such cases of the latter type were included in which during the period of the sickness such phenomena of bone conduction were observed
