This report concerns the frequency of medication and/or medical therapy for 18 infants with hearing-impairment who were treated at Kanazawa University Hospital. Our study assessed the frequency of otitis media with effusion (OME) and/or chronic sinusitis in hearing-impaired children between January and December 2002. All the subjects were using hearing aids. At each visit to our clinic, an ENT doctor checked their ears, nose and throat. The children's history was checked by ENT doctors for OME and/or sinusitis. In all the subjects, ENT disease was identified during the one-year period. Therefore, we stress the importance of otorhinolaryngologic after-care for hearingimpaired children.
