Correlation between macula funtion and basal Electric Compound Action Potentials (ECAPS) in unilateral Cochlear-Implant Patients
Authors
Introduction A Cochlear Implant restores the inner ear function of patients with profound to severe hearing loss. A side effect in some patients can be a positive or negative influence on the vestibular function. One theory is that this can be caused by the anatomical proximity of macula organs and basal cochlear turns. Thus the question arises whether or not a preoperatively impaired macula function comes along with a different pattern of cochlear stimulation responses.
Patients and methods In a retrospective study there were 20 unilateral Cochlear-Implant patients (Advanced Bionics). An analysis of the correlation between preoperatively measured oVEMPs, cVEMPs (ocular and cervical vestibular evoked myogenic potentials) and subjective visual verticales (SVV) and the postoperatively measured NRIs (neural response imaging) of the basal cochlear turns was performed.
Results and conclusion There is a correlation between utricular function and the basal NRIs. However these findings didn´t always correlate with the clinical symptoms of the patients.
