Abstract
This study aims to identify the microorganisms responsible for chronic suppurative otitis media (CSOM) through ear swab cultures and sensitivity testing, followed by appropriate treatment based on the culture results. The effectiveness of the treatment is subsequently evaluated. The findings indicate that the predominant organism isolated was Pseudomonas aeruginosa, accounting for 41.07% of cases, followed by Staphylococcus aureus at 26.79%, Klebsiella at 8.93% and Escherichia coli at 5.36%. Notably, 8.93% of samples exhibited no growth, while commensal organisms were identified in 1.8% of ear discharges. The majority of infections in the study population were classified as Tubo‐Tympanic disease (71.42%), with Attico‐Antral disease following at 23.21%. Gram‐negative organisms constituted 60.7% of the isolates, whereas gram‐positive organisms represented 28.57%. Additionally, 13% of infections showed no microbial growth. The majority of Pseudomonas infections presented with mucopurulent discharge (50%), while S. aureus infections were characterized by a similar discharge in 33.3% of cases. Mucoid discharge was predominantly observed in Pseudomonas (27%) and Klebsiella (16.6%). The study revealed that gram‐negative organisms exhibited high sensitivity to cefoperazone (Cf), gentamicin (G) and amikacin (Ak). Specifically, P. aeruginosa demonstrated the highest sensitivity to Cf (91.3%), followed by G (82.6%), ceftriaxone (Ce) (73.9%), and Ak (65.2%). Klebsiella showed complete sensitivity to Cf and G (100%), with Ak and Ce at 80%. Proteus also exhibited 100% sensitivity to Cf and G, followed by Ak and Ce (66.6%). E. coli showed full sensitivity to Ak, Cf, G and Ce. S. aureus had a high sensitivity to Ak (80%), with G, Ce and Cf all at 66.6%. Acinetobacter demonstrated 100% sensitivity to Ak, Cf and G. The study concludes that P. aeruginosa, S. aureus, Klebsiella and E. coli are the primary pathogens associated with CSOM, with the recommended antibiotics being Cf, G, Ak and Ce. So it becomes very important that each case of CSOM should be studied bacteriologically so as to prevent administration of unwanted antibiotics. This certainly will help in achieving dry ear and preventing complications.
