Background: Chronic suppurative otitis media (CSOM) is a common chronic ear disease causing serious local damage and complications. Irrational use of antibiotics for its management has led to the emergence of multidrug-resistant strains. This study was conducted to find out the microbial profile and their antimicrobial sensitivity patterns in CSOM patients in Garhwal belt.

Methods: A total number of 100 patients of clinically diagnosed CSOM were enrolled over the duration of 1 year. Ear discharge was collected using sterile swabs and processed for the identification of aerobes, anaerobes and fungal isolates. Antimicrobial susceptibility testing of the isolates was performed.  

Results: Maximum incidence of CSOM was observed in patients of 10–20 years age group with female preponderance. Decreased hearing was the main associated symptom. Out of 100 swabs, microbial growth was obtained in 88 samples amongst which 61 had monomicrobial growth while 39 had polymicrobial growth. Pseudomonas aeruginosa was the most common isolate. Amikacin showed maximum activity to most of the isolates.

Conclusions: Evaluation of microbes and their antibiotic sensitivity pattern in local area becomes helpful in prescribing empirical treatment for successful cure of CSOM.
