Abstract
OBJECTIVE: The aim of the present study was to investigate Demodex species infestation in patients with ear itching. The relationship between the severity of ear itching and Demodex spp. positivity has not been previously reported in the literature, and we believe that our study will make a significant contribution to the understanding of the etiology of ear itching. METHODS: Fifty patients with itching ears and 54 healthy control patients were asked to use a visual analogue scale (VAS) to rate the itch, the itching period, and the medication used for the itching. All samples were evaluated for Demodex spp. under a light microscope. RESULTS: There was no statistically significant difference between the groups in terms of numbers of Demodex spp. (p=0.154), and there was no statistically significant difference between the groups in terms of Demodex spp. positivity (p=0.054). Despite the lack of statistically significant differences, Demodex spp. infestations were more common in the affected group than in the control group. A positive and strongly significant relationship was observed between the number of Demodex spp. and severity of ear itch in the patient group based on VAS scores (p=0.0001; r=0.724). CONCLUSION: We found that an increased number of Demodex spp. was strongly related to increased severity of ear itching.
