 Abstract
- Cochlear implantation (CI) has enabled hearing rehabilitation of patients with severe hearing impairment for more than 20 years now. There have been reported that one possible complication of CI is the impairment of balance function with resulting vertigo symptoms. CI still implies trauma on the labyrinthine structures to allow the electrode system to be inserted into the cochlear turns. Benign paroxysmal positional vertigo is an uncommon development after CI. We experienced an 80-year-old woman who had immediate onset of vertigo after CI, which diagnosed in postoperative one day after CI. In postoperative videonystagmography, no spontaneous nystagmus was observed, but in right Dix-Hallpike, torsional nystagmus, where the top of the eye rotates towards the right ear in beating fashion. Vertigo improved after modified Epley maneuver. However there was one recurrence after 12 days later. The case is described along with a review of the literature.
