Abstract:
Post-operative dizziness and vertigo have been variously reported from 30 to 60% after cochlear implantation. There have been reported that delayed vertigo is the most common type and characterized by similarities with dizziness in Meniere's syndrome. Authors experienced a man who had delayed onset of vertigo, which developed six months after cochlear implantation on the left side. Postoperative left caloric response was decreased in both warm and cold stimulation. The direction of spontaneous nystagmus during spell was right side with torsional down beat and definite catch up saccades were observed during head thrust test on the plane of the left horizontal canal and posterior canal, which was resolved on the next day. These episodic and recurrent spells of vertigo might suggest that the hydropic changes of labyrinth corresponding to the pathology of Meniere's disease occurred in this patient.
