Chronic suppurative otitis media (CSOM) is a major health problem in India and a common cause of conductive deafness which may lead to delayed development of speech and language in children. Information regarding the common pathogens and their antibiotic sensitivity is essential for the proper choice of antibiotics. A total of 150 CSOM cases were studied, of which 79 males and 71 females. Majority of the patients were in the age group of 9 months to 20 years. Unilateral infection was more common than bilateral. Pseudomonas aeruginosa (34.93%) was the commonest isolated bacteria followed by Staphylococcus aureus (19.86%) and members of Enterobacteriaceae. Most effective antibiotics were ciprofloxacin (80.14%), gentamicin (71.92%) & amikacin (66.44%) but amoxicillin-clavulanate (6.85%) as least effective.
