Chronic suppurative otitis media (CSOM) is still a major cause of acquired hearing impairment especially in developing countries. Longer the ear discharge persists worse the hearing gets and in some cases the hearing impairment may be profound. Chronicity of discharge is because of the peculiar anatomy of the middle ear, repeated infections from nasopharynx and improper treatment.
1. To study the microbiology of chronic suppurative otitis media. 2. To study the drug sensitivity of the isolated micro organisms.
This prospective study was conducted on 123 ears of 94 patients in the Department of Otorhinolaryngology and Department of Microbiology, Gajra Raja Medical College and associated J.A. Group of Hospitals, Gwalior (M.P.) from August 2009 to October 2010. Aural culture study was done in all the patients. Out of 2 aural swabs, one was inoculated on Robertson Cooked meat medium and the other swab inoculated on nutrient broth. Gram's staining of the slide was also done to have an idea of the type of organism present.
After culture most common organism isolated was staphylococcus aureus 64 (40.7%) followed by pseudomonas aerogenosa 44 (28%). In 32 (26.1%) samples more than one organisms were isolated. Staphyloccus aureus was highly sensitive to cefotaxim in 91% and Pseudomonas was found to be highly sensitive to ofloxacin 80%.Coagulase negative staphyloccus was highly sensitive to gentamycin in 88%.
Antibacterial sensitivity of organisms alter overtime. Staphylococcus aureus being most common oragnism isolated, is highly sensitive to cefotaxim.
