Rapid cVEMP and oVEMP responses elicited by a novel head striker and recording device.

Objective: To develop a reliable, easy to use bedside, office, or field system that allows the rapid measurement of cervical and ocular vestibular evoked myogenic potentials (cVEMP and oVEMP) using a bone-conduction stimulus.

Study Design: Prospective bioengineering design and proof of concept of the test system with saccular and utricular otolith response studies in human subjects.

Setting: Private practice, tertiary neurotology referral center.

Word recognition following implantation of conventional and 10-mm hybrid electrodes.

We compared the effectiveness of 2 surgical interventions for improving word recognition ability in a quiet environment among patients who presented with: (1) bilateral, precipitously sloping, high-frequency hearing loss; (2) relatively good auditory thresholds at and below 500 Hz, and (3) poor speech recognition. In 1 intervention (n = 25), a conventional electrode array was inserted into 1 cochlea. As a consequence, hearing was lost in the implanted ear.
