Abstract
An unselected material of 136 patients with signs and symtoms of acute otitis media were audio-metrically tested with both air and bone conduction. The audiograms were made at intervals during the healing period. The first audiogram was taken before any kind of treatment. No sensonneural hearing impairments were registered. The air-bone gap averaged 20 dB initially but was closed in most cases in 20 days. No permanent hearing impairments were noted. No major differences were noted between the audiograms of patients with spontaneous rupture, myringotomy and no myringotomy.
