Abstract

Our prospective study conducted over a period of 9 months includes 100 samples of ear discharge collected from 90 patients suffering from tubo-tympanic type of chronic suppurative otitis media (CSOM). The ear discharge which is collected with sterile swabs is subjected to Gram’s staining and culture of the causative organism. Antibiotic sensitivity test of cultured bacterial growth is undertaken to know the susceptibility of the causative organism. Of the 100 samples, 62 were culture positive where Pseudomonas aeruginosa was the most common pathogen followed by Staphylococcus aureus. Most of the cultured organisms in our study were sensitive to drug Ciprofloxacin. The outcome of our study enabled us to set an empirical medical treatment for an early resolution of ear discharge and inflammation in our patients with CSOM as we could understand the aetiological pathogens and their susceptibility pattern. Effective medical treatment in obtaining a discharge free ear prior to surgical treatment led us to improve the surgical outcome in our patients with CSOM.
