Introduction: We hypothesized that oxidative stress plays a role in the pathogenesis of chronic otitis media, chronic mucosal inflammatory disease. We aimed to investigate a novel oxidative stress marker in this study. Materıals and methods: Thirty patient with chronic otitis media as the patient group and 30 healthy volunteer subjects as the control group were admitted to the study. Blood samples were taken when they admitted to our clinic before surgical intervention. In healthy volunteers, blood samples were taken when they were admitted to our policlinic.    Thiol/disulphide levels were analyzed with a newly developed method by Erel and Neselioglu. Results: 30 subjects were included in chronic otitis media group (20 females, 10 males).  30 subjects were included in the control group (8 females and 22 males). Sex distribution within the groups was significantly different (p=0.004). There was no significant difference between groups with respect to the age distribution (p=0.072). Measured native thiol, disulphide and total thiol values of the groups were not significantly different from each other. Conclusion: This study demonstrated that although dynamic thiol/disulphide homeostasis was shifted towards disulphide formation as a result of thiol oxidation in patients with chronic otitis media. But we could not find any significant difference between groups.
