Background: Chronic Suppurative Otitis Media is a disease of multiple aetiology and is well known for its persistence and recurrence in spite of treatment. Changes in the microbiological profile following the advent of sophisticated synthetic antibiotics and unscrupulous usage of antibiotics increase the relevance of reappraisal of the modern day organisms in CSOM and their in vitro antibiotic sensitivity pattern. Aim: To identify bacteriological profile in our geographical area in CSOM both in TTD and AAD types, their latest sensitivity trends to antibiotics. Materials & Methods: 100 Patients with more than 3 months history of ear discharge selected over a period of 18 months. All patients are enquired about the history then subjected to ENT examination. From the discharging ear, pus taken with two sterile swabs and sent for direct smear and aerobic culture and sensitivity. Results: Gram negative organisms are predominant than gram positive. Pseudomonas is the most common organism found followed by Staph. aureus. Sensitivity in gram negative bacteria were mainly to Ciprofloxacin, Gentamycin and Amikacin. The gram positive organisms were highly sensitive to Amoxycillin/Clavulanic acid, Amikacin, Gentamycin, Ciprofloxacin and Tetracycline. Conclusion: Bacterial profile in discharging ears keep changing, latest bacteriological profile with antibiotic sensitivities needed to be obtained from time to time so as to treat the patient more efficiently.
