Study design: Observational Study
Abstract: : Chronic suppurative otitis media(CSOM) is a chronic inflammation of the middle ear cleft characterised by persistent tympanic membrane perforation with intermittent or continuous purulent or mucopurulent discharge from the ear canal for more than 2 weeks to three months. : We collected 249 growth isolates from patients of CSOM. We isolated and identified the common organism of CSOM and studied antibiotic susceptibility patterns. : In our study, patient ages range from 1 year to 75 years. Most patients were male. the maximum number of patients (69%) were from age group 1-15. The most common organisms isolated were Spp (37%), followed by (30%) and (14%). Majority of Spp is were susceptible to Imepenem (100%), Piperacillin-Tazobactam (77%) and Amikacin (69%). Majority of the other Gram negative bacilli isolates were also susceptible to these antibiotics. Most of the Staphylococci were susceptible to linezolid and ofloxacin. 39% of Spp and 34% of were multidrug resistant (MDR). Spp. followed by Staphylococcus Spp were the two common causative organisms of CSOM. Based on this study, suggestions for empirical antibiotics are Amikacin for gram negative bacilli and ofloxacin for Staphylococcus Spp.
