Abstract

Chronic Suppurative Otitis Media (CSOM) is a long standing infection of middle ear characterized by ear discharge and permanent perforation. Ranchi is amongst those geographical areas in India which have environmental factors favouring frequent upper respiratory infections resulting in a higher incidence of persistent and recurrent Otitis Media, which in turn leads to complications. Hence the present study was done to observe the aerobic bacterial flora in causation of CSOM and their antimicrobial susceptibility pattern. 336 samples of ear discharge from 310 patients of CSOM were studied, out of which 297 were culture positive. The most predominant bacteria was Staphylococcus aureus followed by Pseudomonas aeruginosa. Sensitivity of Staphylococcus was good to Vancomycin, Cloxacillin, Linezolid, Cefalexin, Cotrimoxazole, Clindamycin, Ciprofloxacin and Amoxyclave while 25.9% were MRSA. Pseudomonas showed high susceptibility to Meropenem, Sulbactam-Cefoperazone, Chloramphenicol, Ceftazidime, Ciprofloxacin, Piperacillin-Tazobactum and Amikacin. Therefore the present study proved useful for clinicians in knowing the predominant pathogen and their susceptibility pattern for the appropriate management of CSOM patients.

KEYWORDS: Chronic Suppurative otitis media, Aerobic Bacterial, Staphylococcus aureus , Antibiotic sensitivity pattern.
