Relationship between Itching and the Presence of Demodex Species in the External Auditory Canal in Patients with Chronic Ear Itching

Objective: The aim of this study was to investigate the relationship between ear itching and Demodex and to reveal the presence of Demodex in the aetiology of ear itching. Our study will contribute to this area, where there is a limited number of studies in the literature, and treatment planning can be provided by considering this aetiology in patients with chronic ear itching.Material and Methods: Fifty-two patients with chronic ear itching and 51 patients without itching were included in the study. The patients’ itching severity was assessed with the VAS (visual analog scale). A sample with the plug was taken from the external auditory canal. Demodex mites were investigated by examining the obtained samples using a light microscope. Results: There was no statistically significant difference between the groups with and without ear itching in the presence of Demodex mites (p=0.09). However, Demodex positivity was found to be higher in the patient group with itching (53.8%). There was no statistically significant relationship between the presence of Demodex and VAS scores measuring itching severity (p=0.89).Conclusion: In our study, the presence of Demodex mites was found to be numerically higher in patients with chronic ear itching. We believe that Demodex mites play a role in the aetiology of ear itching.
