Abstract : Objective: Although many studies have shown relation between chronic otitis media(COM)and sensorineural hearing loss(SNHL),there still remains controversies about the relationship.The purpose of this study was to determine whether COM is associated with SNHL?Methods:127 patients met the following criteria:unilateral COM and no history of head trauma,meningitis,post traumatic tympanic membrane perforation,acoustic trauma,ototoxic drugs,previous ear surgery and systemic diseases that can affect hearing of the patients.The average bone conduction(BC) threshold at 500,1000,2000,4000HZ separately in COM ear and normal ear was compared using the t-test and MANOVA techniques.Results:Average BC at 500,1000,2000,4000HZ in normal ear was 10.76▒7.19 and 18.82 ▒ 11.55 in COM ear.The differences between BC threshold at 500,1000,2000,4000 HZ and average BC threshold at 500,1000,2000 HZ in the COM ear were statistically and probably clinically significant. (Pvalue<0.001 ))Conclusion :COM is associated with SNHL and has clinical importance..
