Sensorineural Hearing Loss in Chronic Otitis Media: A Cross Sectional Descriptive Study at Tertiary Care Hospital

Abstract

OBJECTIVE: To determine the frequency of sensorineural hearing loss in chronic suppurative otitis media.
 MATERIAL AND METHODS: A cross sectional descriptive study was done at department of ENT-B, Hayatabad Medical Complex (HMC), Peshawar, from March 2016 to September 2016. 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. Forty five percent patients were male while 55% patients were female. More over the incidence of sensorineural hearing loss was found to be 18% in patients with chronic suppurative otitis media.
 CONCLUSION: The incidence of sensorineural hearing loss was found to be 18% in patients with chronic suppurative otitis media.

Otitis Media with Persistent Inflammation is a Common Cause of Sensorineural Hearing Loss

“…Similar and precise results were interpreted based on the most recent study, which found that 47.8 percent of SNHL patients were reported in the second year after the complaint. [25] Higher frequencies were reported to be more affected in individuals with COM who had a substantial degree of SNHL by Kolo ES et al [26]. While older individuals and those with longer histories of otorrhea tend to have more severe SNHL, neither of these factors appears to correlate with the severity of SNHL in patients with COM.…”
