About this study

The objective of this study is to identify possible preoperative risk factors including genetic background and to suggest the optimal test battery of vestibular function in cochlear implant recipients Participants underwent standard vestibular testing including video head impulse test (vHIT), vestibular evoked myogenic potentials (VEMP), subjective visual vertical and stabilometry before and after the surgery.
