Introduction: Aim of this study is to identify the microbes causing active mucosal Chronic otitis media (COM) and to know sensitivity pattern in this group.

Materials and method: Pus swabs were collected using sterile swabs and sent to microbiology laboratory to be cul-tured immediately. Antibiotic susceptibility was assessed with Kirby-Bauer disc diffusion method.

Results: The most common microbes isolated were Staphylococcus aureus followed by Pseudo-monas aeruginosa. The most effective antibi-otic against Staphylococcus aureus is linezolid and for Pseudomonas aeruginosa is piperacil-lin-tazobactam.

Discussion: Pseudomonas aeruginosa followed by Staphylo-coccus aureus is the common known bacteria isolated but in our study staphylococcus aureus followed by pseudomonas aeruginosa was the common isolate. Our empirical antibiotic policy is oral erythromycin with topical ofloxacin.

Conclusion: The trends in antibiotic policy have to be re-viewed from time to time, to see the changing susceptibility pattern of the bacteria.
