Tympanostomy tubes were inserted in 82 ears under local anesthesia of the ear by iontophoresis in our clinic between the beginning of 1985 and the end of 1988. After 3 months,6 months and 9 months, hearing was tested in two groups of patients: those with tympanostomy tubes indwelt for 3 months or longer and those with indwelt for less than 3months. Hearing improvement was greater in the former than in the latter groups. Otorrhea was observed in 13 ears (16%) while the tympanostomy tubes were in their proper places. The cases administered Betamethasone sodium phosphate by ear drippings are more often infected significantly. The air-bone gaps of adults are larger than those of young patients after tympanostomy with tubes. These phenomena may be related to the sequelae after OME. OME recurred in 36% of the patients after tympanostomy tubes were indwelt.
