Abstract
PURPOSE: Chronic suppurative otitis media (CSOM) is the major cause of hearing impairment, especially conductive hearing loss. Few patients also had sensorineural component, the sensorineural hearing loss (SNHL) in CSOM is controversial, especially for safe mucosal type. This study aims to assess the relationship between the frequency of SNHL development in patients with safe mucosal CSOM and its relation to patient's age, sex, duration of disease, size of perforation and different audiological findings. MATERIAL AND METHODS: This is a prospective study conducted from June 2016 to June 2017 in a tertiary referral hospital. 200 patients with unilateral mucosal type of CSOM with normal contralateral ear were included in the study. The diseased ears were taken as study ears and normal ears as control ears in all patients. Detailed otologic history, clinical and audiometric findings were recorded and analyzed. Results were statistically compared in all patients for both study and control ears using different parameters. RESULTS: Twenty patients had an average bone conduction threshold of all frequencies above 25dB, which implies SNHL (10%). The incidence of SNHL was statistically significant at higher speech frequencies. The incidence increased with the presence of Diabetes Mellitus, smoking, duration of disease, presence of active discharge and the increase in size of perforation. However, it is not age dependent and there was no difference between males and females. CONCLUSION: Safe mucosal CSOM can cause SNHL with multiple predisposing factors.
