Long-term outcome of canal paresis of a vascular cause.

There have been several reports on the progress of the caloric response of vestibular neuritis, but little is known about the recovery of canal paresis (CP) of a vascular cause. This study found that the caloric response normalised in 20 (67%) of 30 patients with CP associated with posterior circulation ischaemic stroke who were followed for at least 1 year (mean, 42.5 months; range, 14-85 months).
