Present vestibular status of subjects implanted with auditory prostheses.
Electronstagmographic studies were performed on all 13 patients with the caloric stimulus series, omitted in two subjects with external otitis. Eleven of the 13 subjects exhibited normal eye movement screening tests. Of the remaining nine subjects who could be evaluated, all demonstrated markedly reduced or absent caloric-induced nystagmus responses. These results confirmed preoperative vestibular test findings performed by implant surgery teams and indicated that the vestibular systems of the patients were severly damaged.
