Abstract:   (22374 Views)
This study has been performed on show the incidence of sensory neural hearing loss (SNHL) in patients with chronic Otitis Media (COM) and it’s different parameters. 207 patients with persistent or previous otorrhea have been examined. 70 patients had bilateral otorrhea and 137 patients had unilateral problem so overall 277 ears are evaluated. The BC greater than 15 dB without carhartnotch was the basis for diagnosis of SNHL. 66 patients had SNHL and of them 26 cases were bilateral so total number of ears with SNHL were 92 (The incidence of SNHL was 32.2%). 3 cases were due to other causes like TB (1 case) RM fistula (1 case) and squamous cell carcinoma (SCC) of middle ear (1 case). About 90.3% of cases had down slooping high frequency SNHL in their audiogram. In 47.6% of the ears with granulation tissue and cholesteatoma had SNHL while 28.7% of cases with chronic perforation revealed SNHL. Analysis of this study showed that there is a probability of increased SNHL during old ages the cases of prolonged and persisted otorrhea also revealed a higher incidence of SNHL. We didn’t disclose correlation between age and severity of SNHL.
