Retrospective study of chronic otitis media on 339 cases was carried out. The results were summarized as followed;1) Many kinds of pathogenic micro-organisms were isolated, consisting of 25 species with 427 strains. The frequency of mixed infection was 23.0 percent of the total cases.2) Staphylococcus aureus was the most frequent species detected from otorrhea, followed by pseudomonas aeruginosa, proteus inconstans, proteus mirabilis, staphylococcus epidermidis and the other 20 species of low incidence.3) Genus proteus bacilli were isolated with significantly higher incidence from otorrhea of cholesteatoma than that of chronic suppurative otitis media.4) The results of the antimicrobial agent susceptibility test revealed that the combined use of SBPC with GM was the most effective regimen for the emergent stage of chronic otitis media such as otogenic intracranial complications.
