CLINICAL AND BACTERIOLOGICAL STUDY OF CHRONIC SUPPURATIVE OTITIS MEDIA BY ANAEROBIC CULTURE METHODS IN A TEACHING HOSPITAL

Abstract

Objective:

To observe the types of organisms grown in CSOM  both Tubotympanic (TT) and Atticoantral (AA) type

Material and Methods:

This was  a  prospective study conducted between October 2009 to June 2011 in tertiary referral center in India.120 chronic and actively discharging ears of 100 pateints were included in study.

Results:

Majority of patients were in age range 26 to 35 years. 69 % of patients were from low socioeconomic group. CSOM-TT was found in 81.67% and CSOM-AA in 18.88% cases. Out of 120 swabs only 113 swabs grew bacteria. Out of 120 swabs, 48.35% swabs grew monomicrobial isolates and 48.83% swabs grew polymicobial isolates. Aerobic growth was seen in 48.33 anaerobic growth was seen in 2.5 % and mixed flora was seen in 43.34% and no growth was seen in 5.83%. In COSM-TT commonest anaerobic was prevotella whereas peptostreptococcus was common in CSOM-AA.

Conclusion:

In COSM-TT commonest anaerobic was prevotella whereas peptostreptococcus was common in CSOM-AA.
