Keywords:
Chronic, suppurative, otitis media, microbiological culture, antibioticsAbstract
Objective: To find out the frequency and drug sensitivity of different bacteria causing chronic suppurative otitis media
(CSOM) in adult patients visiting a tertiary care hospital in Peshawar, KP.
Material and Methods: This is a descriptive cross sectional study, carried out at ENT Department, Khyber Teaching
Hospital, Peshawar, Pakistan from February 2015 to January 2016. One hundred and twenty-eight ear swabs were taken
from patients diagnosed as cases of chronic suppurative otitis media on the basis of history and clinical examination,
who have not taken any local or systematic antibiotic treatment for the last one week. Patients taking steroids or suffering
from any co morbidity like chronic renal failure, diabetic’s mellitus or any disease which may affect the immune
system were excluded from the study.
Results: Out of total 128 ear swabs, 51.5% shows Pseudomonas aeruginosa, 29% staphylococcus, 12% proteus, while
E. Coli, Klebsella, and streptococcus pneumonia were the less commonly involved organisms. Regarding the sensitivity
of antibiotics 90% were sensitive to ciprofloxacin, 88% to amikacin and 83% to ceftazidime.
Conclusion: Pseudomonas aeruginosa and staphylococcus aureus were the commonest organism causing CSOM.
Ciprofloxacin can still be found to be the most potent antibiotic against all common pathogens.
