In this study a total of 174 patients were observed by using 95% confidence interval and 5% margin of error with expected frequency of sensorineural hearing loss 13% among cases with chronic suppurative otitis media with the help of WHO formula for sample size determination. More over consecutive (non-probability) sampling technique was used for sample collection. RESULTS: In this study mean age was 26 years with standard deviation +- 11.62.
