Background: Chronic suppurative otitis media (CSOM) is the commonest clinical condition diagnosed in ENT out patients department (OPD) in the developing country like: India. CSOM can lead to serious intracranial/extracranial complications. Hence knowledge of local bacteriological pattern and its antibiotic sensitivity may help for treating them with appropriate antibiotic therapy.
Methods: This prospective study was done with the collaboration of ENT and microbiology department. in a tertiary care centre, India The pus sample was collected from clinically suspected CSOM patients and culture sensitivity as done. Identification of bacterial isolates and antibiotic susceptibility patter was done by standard CLSI guidelines.
Results: On assessing about 122 patients of CSOM, most of them (2 group with male predominance. The commonest organism isolated was Pseudomonas species (24.2%) followed by klebsiella. Pseudomonas species was most sensitive to imipenem, colistin and polymixin b Staphylococcus aureus was mainly sensitive to linezolid and Vancomycin.
Conclusion: The study concludes imipenem for Pseudomonas species and linezolid and Vancomycin for Staphylococcus was most sensitive drug. The appropriate and adequate antibiotic therapy is always recommended for chronic otitis media to avoid complications.
