Abstract
INTRODUCTION: Chronic Suppurative otitis media (CSOM) denotes chronic inflammation within the mucosa of middle ear and mastoid leading to production of ear discharge via tympanic membrane perforation. (1) CSOM results [...]
INTRODUCTION: Chronic Suppurative otitis media (CSOM) is the most common condition encountered by otolaryngologists in day to day practice. The importance of chronic otitis media lies in its dreaded complications and deafness. AIM: This study was under taken to identify the microbiological isolates of the ear discharge in CSOM cases and their sensitivity to antibiotics. SETTINGS AND DESIGN: Tertiary care hospital in north costal Andhra Pradesh. It was a Prospective study. MATERIALS & METHODS: About 100 patients having ear discharge who attended ENT outpatient department from July 2013 to Feb 2014 for a period of 8months were studied. Aural swabs were sent to microbiology lab for culture &sensitivity. RESULTS: Culture reports showed aerobic bacterial isolates in 85 cases, fungi in 7 cases and sterile in 8 cases. Of the 85 cases of aerobic bacteria, staphylococcus aureus was isolated in 34 cases (40%) followed by Pseudomonas aeruginosa in 29 cases (34%), klebsiella in 16 cases (18.8%), E.coli in 4 cases (4.7%) and proteus in 2 cases. Antibiotic sensitivity reports showed Staphylococcus was more susceptible to netilmycin (97%), amoxiclav (91.7%) and least sensitive to ceftazidime (64.7%). Pseudomonas was more sensitive to amikacin (96.5%), gentamycin (93.1%) and least sensitive to amoxyclav (79.3%), ampicillin + sulbactum (82.75%). CONCLUSION: Mono microbial etiology, especially Staphylococcus species was found to be the most common organism causing chronic otitis media. Knowledge of the prevailing flora and their susceptibility to antimicrobials will guide the clinicians for early and effective treatment thereby avoiding complications. KEYWORDS: Chronic Suppurative otitis media, culture and sensitivity, Staphylococcus aureus
