Bacteriological studies were carried out for the purpose of determining the kinds of bactaria detectable before, during and after tympanoplasty as well as to find out their survival rate on 55 cases (61 ears) with chronic otitis media who had been treated in our clinics during the two-year period from July 1958 to June 1960. The following are the results.<br>1. Out of the 98 strains of bacteria detected before the operation, the most numerous were Staphylococcus aureus (16 strains), followed by Pseudomonas aeruginosa (12 strains), Diphtheroid (12 strains), Diplococus pneumoniae (8 strains), Pneumococcus mucosus (7 strains.) and Micrococcus (7 strains) in the order mentioned.<br>2. In connection with the preoperative detection of bacteria, mixed infection was found to be a two-fold simple infection. As for the different kinds of bacteria, simple infection by Staphylococus aureus was twice as frequent as by other bacteria, while in the cases of infection by the other bacteria the majority proved to be of mixed infection.<br>3. Simple infection decreased during and after the operation, whereas mixed infection, although it did decrease during the operation, increased again postoperatively.<br>4. Staph. aureus completely disappeared during or after the operation, while Pseudomonas aeruginosa, Diplococcus pneumoniae, and Diphtheroid proved to be persistent, not decreasing so readily during or after the operation. Therefore, in the cases where these bacteria are detected prior to tympanoplasty, every possible care needs to be taken for the disinfection during the operation.<br>5. Of the detectable bacteria, Gram-positive ones were twice as numerous as the Gram-negative.<br>6. Such saprophytes as Bacillus fusiformis, spore forming bacteria and Serratia marcescens were also detected, although they were very small in number.<br>7. Those that could not be detected at all were Mycobacterium tuberculosa, Haemophilus influenzae and true Fungi such as Candid.
