Imad ., Mohtasim Billah, Sanaullah ., Sadia Farhad


BACKGROUND: Chronic otitis media is a common problem especially in the under developed part of the world causing a number of complications. Improper use of antibiotics is a major contributing factor .This can be prevented by knowing the involved organisms and their sensitivity to different types of anti microbes.

OBJECTIVE: To find out the frequent microbes involved in chronic otitis media(COM) and their sensitivity to various anti bacterials.

MATERIAL AND METHODS : In our study 170 patients visiting E.N.T. OPD At Mardan Medical Complex Teaching Hospital Mardan from January 2016 to December 2016 for discharging ears were included. Patients already treated elsewhere partially treated or with complications were excluded from the study .Thorough history, physical examination and investigations were done .Pus swabs were taken from discharging ears under strict aseptic technique and sent to BKMC Pathology lab for culture and sensitivity.

RESULTS: Out of 170 patients,102 were Males and 68 Females .Most frequently isolated organism was Pseudomonas Aeuroginosa (64.7%) followed by Staph Aureus(25.88%) and Proteus (4.7%) etc. Sensitivity to ciprofloxacin, imepenem, amikacin and polymyxin was found in different cases. Most of the organisms were found resistant to Gentamicin , Pencillin and Erythromycin.

CONCLUSION: Microbial study and culture sensitivity determines the organisms involved in chronic otitis media and to treat the disease with proper antimicrobials for successful outcome.
