Learning Objectives:

Introduction: Dizziness is a common side effect to cochlear implant (CI) surgery. Regarding the CI surgical technique, there is no clear evidence if one approach (round window approach) leads to less dizziness than another approach (cochleostomy).

The main objective to this study is to investigate any difference between the two surgical approaches measured by video head impulse test (vHIT). Secondly we compare the objective findings with the subjective dizziness perceived by the patient.

Method: Fifty patients who will undergo CI surgery at OUH will be examined with vHIT prior to their surgery, the day after their surgery and one month after. They will fill out a Dizziness Handicap Inventory (DHI) scheme and VAS score according to their dizziness.

Subjects are randomized to either the round window approach or the cochleostomy approach. Subjects are stratified according to age (+/− 60), hearing rest and gain prior to surgery (+/-0,68). The randomization is blinded for investigator and subject.

Inclusion period ends at 1st of April 2016.

Results: Results will be revealed at the conference.

Conclusion: The results of this study could have influence on the future choice of approach of electrode insertion in cochlear implant surgery.
