Objective: This study aimed to administer cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP) tests to patients with idiopathic sudden sensorineural hearing loss (ISSHL) before and after treatment. Material and Methods: The study included 60 patients aged 18-65 years. The individuals were divided into 2 groups: One comprised individuals diagnosed with ISSHL (n=30), and the other was a control group (n=30). All individuals underwent cVEMP and oVEMP tests before and after treatment, and individuals who complained of dizziness or nausea along with sudden hearing loss were further examined using a visual analog scale (VAS) and the Dizziness Handicap Inventory (DHI). Every patient with SHL was also questioned regarding the existence of tinnitus. Results: The pre-and post-treatment VEMP results for ears impacted by idiopathic ISSHL were compared. A notable decrease in N1 latency was observed in the cVEMP scores following treatment (p<0.05). Upon comparing the pre-and posttreatment DHI, VAS, and tinnitus scores of individuals with ISSHL and dizziness, the total scores before treatment were considerably higher than the post-treatment levels (p<0.05). Conclusion: Patients with ISSHL are more prone to vestibular disorders because their otolith organs are anatomically closer to the cochlea. VEMP testing can be used to investigate vestibular function in these patients.
