ABSTRACT
Background and Objectives: Chronic otitis media (COM) poses a major health problem in developing countries causing serious socioeconomic consequences and occasional life threatening complications. Early and effective treatment based on the antibiotic sensitivity of the microbes is the key for effective management. This study was done to find out aerobic microorganisms responsible for chronic otitis media (COM), in both mucosal and squamosal disease and to study the antibiotic sensitivity pattern of the organisms isolated.
Materials & Methods: 100 patients with COM were included in the study. The patients had chronic ear discharge and had not received antibiotics for the last two weeks. Swabs were taken and cultured for microbial flora. Drug susceptibility testing for aerobic isolates was conducted by Kirby-Bauer’s disc diffusion method.
Results: Out of 100 patients 88 were diagnosed with mucosal disease and 12 squamosal disease. Analysis of this study showed predominance of gram negative organisms (60%). The highest incidence was that of Pseudomonas aeruginosa (42%), followed by Staphylococcus aureus (21%). Antimicrobial profile revealed maximum sensitivity to gentamicin (75%), ciprofloxacin (70% and Amikacin (66%).
Conclusion: Knowing the aetiological agents of COM and their antimicrobial susceptibility is important in effective treatment and prevention of complications and development of antibiotic resistance and finally cost-effective management.
