The extent of vestibular impairment is important in recovery of canal paresis of patients with vestibular neuritis

We questioned whether the extent of vestibular impairment affected the recovery of vestibular function in acute vestibular neuritis (VN). The objective of this study was to identify how the extent of vestibular impairment influenced the recovery from canal paresis (CP) in patients with VN. We retrospectively reviewed the medical records of 46 patients diagnosed with acute vestibulopathy between January 2012 and December 2015. Pure-tone audiometry, a caloric test, and cervical vestibular evoked myogenic potential (cVEMP) testing were performed in all patients. Patients were divided into two groups, superior VN and total VN, according to the results of the cervical vestibular evoked myogenic potential (cVEMP) testing. The caloric test was rechecked 6–12months after diagnosis and the CP values were compared at 6 and 12months. The degree of recovery was evaluated by comparing the CP values. We defined good recovery as CP
