Chronic suppurative otitis media (CSOM) is defined as a chronic inflammation of
the middle ear and mastoid cavity. The disease usually begins in childhood. We
need to study the prevalence and risk factors of chronic suppurative otitis media
in a teaching hospital in Telangana.
This was a cross sectional study done among patients with CSOM attending the
Department of ENT for a duration of one year from January 2019 to December
2019. Detailed history, otoscopic examination and culture sensitivity tests of ear
discharge were done.
The sample size was 150. The prevalence of CSOM was reported to be 7.5 %.
Majority of the cases were in the 11 - 15 years age group, i.e., 56.6 %.
Tubotympanic type was most commonly reported and accounted for 80 % (100 /
150) whereas atticoantral type was 20 %. Pseudomonas aeruginosa was the most
commonly isolated organism from the ear discharge. Most of the CSOM cases
presented with upper respiratory tract infection i.e., 20 %.
The prevalence of CSOM in our study was 7.5 % and it was more common in the
younger age group. CSOM was more common in the lower socioeconomic class.
Upper respiratory tract infection is a frequent mode of presentation of CSOM.
