Abstract


Background: Chronic suppurative otitis media (CSOM) is a massive public health problem in developing countries like India, especially among low socio-economic class because of malnutrition, overcrowding, poor hygiene, inadequate health care and recurrent upper respiratory tract infections. CSOM cases unless managed effectively may land into various complications such as persistent otorrhoea, hearing impairment, mastoiditis, labyrinthitis, facial nerve paralysis to more serious intracranial abscesses.

Methods: The study was carried out in a tertiary care hospital from January 2017 to December 2017 with an aim to determine the microbiological profile of ear discharge in patients suffering from CSOM and their antimicrobial susceptibility pattern using Kirby Bauer disc diffusion method.

Results: Out of 630 samples processed, 407 (64.6%) samples were culture positive. Most common organism isolated was Pseudomonas spp. (43.2%) followed by S. aureus (39.1%). Most of isolates recovered were multidrug resistant.

Conclusions: Management of CSOM consists mainly of eradicating infection and closure of tympanic membrane. Periodic monitoring of bacterial isolates and their antibiotic susceptibility pattern is necessary for administering appropriate antibiotics as empirical treatment and also helps in reducing the potentially disabling and fatal complications of CSOM.
