Vestibular Function After Cochlear Implantation Using Soft Surgery Techniques

Completed · Not applicable

Conditions studied: Vestibular Function in Cochlear Implant Patients

In brief

This study will measure the effects of soft surgical techniques on vestibular function and quality of life in patients pre- and post-cochlear implant (CI) surgery. Additionally, the investigators will attempt to systematically evaluate the utility of different electrophysiological measures of vestibular system function in surgical ears. Vestibular system function in CI patients will be evaluated pre-surgically and twice post-surgically, at 3 months and again at 1 year post-surgery. Traditional test techniques - such as VNG, rotational testing, and air conduction VEMPs - will be compared to and cross-checked with newer techniques including video head impulse testing (vHIT) and bone conduction VEMPs.
