The aim of this study was to investigate the usefulness of eardrop treatment in patients with otitis externa and media. The survey using a questionnaire revealed that OFLX and CMX were used in 78.1％ of 228 patients who visited ENT doctors in Toyama between January and July, 2000. The clinical efficiency of the treatment was determined according to the criteria by Baba et al., which were based on changes of major symptoms after administration of eardrops. The rates of effectiveness were 81.8％ in otitis externa, 98.1％ in acute suppurative otitis media and 86.2％ in chronic otitis media. The combined administration of topical and systemic antibiotics in chronic otitis media patients was less effective on symptoms than only topical administration. On the other hand, ear cleaning treatment of by ENT doctors such as washing, wiping and suctioning of aural discharge accompanied with topical eardrops was much more effective in reducing otorrhea than only eardrop treatment. Bacterial replacement after the topical administration of antibiotics was observed in only one patient who continued to use eardrops against the doctor's instruction. In conclusion, administration of eardrops was very useful and the combination of eardrops and ear cleaning by doctors was helpful to cure otitis externa and suppurative otitis media.
Key words : topical ear treatment, eardrop, otitis externa and suppurative otitis media
