Article Synopsis
- - The study investigates how skull vibrations at different frequencies cause nystagmus (involuntary eye movement) in patients with vestibular neuritis, specifically observing the frequency impact on nystagmus characteristics.
- - A total of 63 patients were tested with video head impulse tests (vHIT) and skull vibrations at frequencies of 30Hz, 60Hz, and 100Hz, finding increasing positive SVIN results with higher frequencies.
- - Results showed a significant correlation between the asymmetry in ear function measured by vHIT and the speed of nystagmus at 100Hz, indicating that ear function differences can inform the extent of vestibular disturbance in patients.
Objective: To evaluate vestibular function before and after cochlear implantation (CI) STUDY DESIGN: A prospective descriptive study.
Material And Methods: Thirty consecutive patients with profound sensorineural hearing loss undergoing CI. Objective assessment of vestibular function was performed with the caloric test and video head impulse test (vHIT) in patients before and after CI.
Electrode array misplacement is an infrequent complication in cochlear implant surgery. A case report of electrode array insertion into the posterior semicircular canal, and its effects on the vestibular function is described. Video head impulse test (vHIT) has become an exceptional diagnostic tool to study vestibular function.

Study Design: Retrospective cohorts study in a tertiary referral hospital. Forty-nine consecutive patients on which vestibular schwannoma surgery was performed at least 1 year before.
Conclusions: The degree of caloric weakness before surgery influences faster or slower recovery of patients undergoing vestibular schwannoma surgery. The Dizziness Handicap Inventory (DHI) is a good index to show the recovery of patients as it relates directly to an improvement or not of the subjective visual vertical (SVV).
Objective: To evaluate the process of recovery of patients as measured by the SVV and the DHI after surgical removal of vestibular schwannoma.
