Functional Assessment of Hearing and Vestibular Function Tests

We present the results of the vestibular function tests of 35 patients who were selected for cochlear implantation. Vestibular function was evaluated with a caloric test and a velocity step test. The preimplant data were compared to those in previously reported series. Intracochlear implantation was performed in 25 patients. The vestibular complications encountered in this group are presented and discussed. Six patients had normal or residual (but substantial) vestibular function in the ear eligible for implantation. Vestibular function was preserved in 3 patients and was lost in 3 patients, in 1 case through an iatrogenic cause. We estimate the risk of losing vestibular function as a result of intracochlear implantation as between 50% and 60% on the basis of the present and previously reported data.

Pursuit Gain

The effectiveness of pursuit gain, cancellation of the vestibulo-ocular reflex, and a clinical oscillopsia test were assessed as vestibular function tests and tests that may allow prediction of which patients would compensate poorly after vestibular surgery. Cancellation of the vestibulo-ocular reflex in 17 patients and 17 control subjects was compared. Pursuit gain for 17 patients was determined for three frequencies at peak velocities of 25 and 50 degrees/sec. The oscillopsia test was administered to seven patients during at least the first 6 postoperative months. We are unable to state that any of these parameters were effective “markers” of impaired compensation, but the oscillopsia test appears to be a useful clinical tool for vestibular examination.
