Abstract

BACKGROUND: Chronic suppurative otitis media is one of the most common disease in the otolaryngologic field. It is important to choose of antibiotics in the management of chronic suppurative otitis media.
OBJECTIVES
Bacteriologic studies can make it possible to use appropriate antibiotics.
MATERIALS AND METHODS
The bacteriologic study was made on 98 cases of chronic suppurative otitis media who visited the department of otolaryngology, Dae Dong Hospital in Pusan from Nov. 1989 to Dec. 1995 and the following results were obtained.
RESULTS
1) In 90 cases in which pathogenic organism was isolated, single infection was 81 cases(90%) and mixed infection was 9 cases(10%). 2) The most frequent pathogenic organism was Staphylococcus(46.5%) and Proteus(16.1%), Pseudomonas(14.1%), Providencia(10.1%) were the next. 3) In the aspect of the sensitivity to antibiotics, Ciprofloxacin, Ceftriaxon and Amikacin were sensitive drug generally. 4) Staphylococcus was sensitive to Vancomycin and Ciprofloxacin. 5) Proteus was sensitive to Amikacin, Ciprofloxacin, and Ceftriaxon. 6) Pseudomonas was sensitive to Ciprofloxacin, Amikacin and Piperacin. 7) Providencia was sensitive to Ciprofloxacin, Ceftriaxon, Amikacin and Piperacin. 8) Methicillin Resistant Staphylococcus Aureus(MRSA) was 19 Strains(45.5%).
CONCLUSION
Recently, pathologic strain and it's sensitivity to antibiotics has changed. So, we recommand that periodic bacteriologic study and sensitivity test should be done for effective management of chronic otitis media.
