“…The recovery from SVV tilt after an acute vestibular deficit (neurotomy, vestibular schwannoma surgery, and neuritis) has already been described [Vibert and Häusler, 2000;Lopez et al, 2007;Batuecas-Caletrio et al, 2013]. In these studies, the SVV values gradually normalized after 6-12 months, long after the disappearance of the vertigo.…”

“…In these studies, the SVV values gradually normalized after 6-12 months, long after the disappearance of the vertigo. It was previously reported that in patients with a temporoparietal stroke or a vestibular neurotomy, a tilted SVV appears to be related to persistent vestibular symptoms [Min et al, 2007;Batuecas-Caletrio et al, 2013]. Indeed, visually guided movements such as those used in SVV evaluation implicate the transformation of a position in space to coordinates related to a body-centered reference frame.…”

The subjective visual vertical (SVV) is an indicator of vestibular otolithic function and mainly processed by the nondominant parietal cortex. We investigated the hypothesis that recovery from SVV tilt after vestibular neuritis can be influenced by the body's lateral preference. This prospective cohort follow-up study included 254 consecutive adult patients with vestibular neuritis. The recovery from SVV tilt was faster in patients with a left hand or eye dominance than in those with a right dominance. While in left-handers the side of the neuritis did not affect the speed of recovery, in right-handed subjects, the recovery from a right-sided neuritis was significantly slower than from a left-sided affection. These observations suggest that subjects with a left sensorimotor dominance have developed more significant midline-crossing projections to the parietal cortex, allowing them to cope faster with a unilateral vestibular deficit.

“…For example, two other investigations showed that only 40% to 60% of elderly patients with confirmed BPPV reported vertiginous symptoms compared with 90% of young adult patients with BPPV (21,23). Instead of vertigo, elderly patients with BPPV more frequently reported unsteadiness and imbalance.…”

ObjectiveTo evaluate vestibular compensation via measurement of the vestibulo-ocular reflex (VOR) following vestibular schwannoma surgery and its relationship with changes in saccades strategy after surgery.PatientsThirty-six consecutive patients with vestibular schwannomas, without brainstem compression, underwent surgical resection. Patients were recruited from University Hospital of Salamanca, Spain.MethodsWe assessed the age, sex, tumor size, degree of canalicular weakness, and preoperative video head impulse test (gain and saccade organization measured with PR score). Gain and saccade organization were compared with postoperative values at discharge and also at 1, 3, and 6 months. PR scores are a measure of the scatter of refixation saccades.ResultsPatients with normal preoperative caloric function had higher PR scores (saccades were scattered) following surgery compared to patients with significant preoperative canal paresis (p < 0.05). VOR gain and the presence of covert/overt saccades preoperatively did not influence the PR score (p > 0.05), but a group of patients with very low VOR gain (<0.45) and covert/overt saccades before surgery had lower PR scores after surgery. The differences after 6 months were not significant.ConclusionPatients with more severe vestibular dysfunction before vestibular schwannoma surgery show significantly faster vestibular compensation following surgery, manifested by changes in VOR gain and PR score. The scatter of compensatory saccades (as measured by the PR score) may be a surrogate early marker of clinical recovery, given its relationship to the Dizziness Handicap Inventory.
