Objective: To investigate the clinical characteristics of patients with dizziness/vertigo accompanied by loss of the posterior canal(s) (LPC).Methods: Clinical data of 23 patients with LPC were collected. We determined video-head-impulse test (vHIT) gains of all six semicircular canals and correlated vHIT findings with other vestibulo-cochlear tests, including caloric test, ocular and cervical vestibular-evoked myogenic potentials (oVEMP, cVEMP), pure tone audiometry (PTA), and analyzed the differences in clinical manifestations of patients with LPC with different etiologies.Results: LPC was identified in 23 patients. At the time of disease onset, most patients presented with dizziness (47.8%) and vertigo (30.4%) only, and some patients (21.7%) complained of unsteadiness. Among these 23 patients with LPC, there were 14 (60.9%) patients of isolated LPC (ILPC), 21 (91.3%) patients of unilateral LPC (ULPC), and 2 (8.7%) patients of bilateral LPC (BLPC). (1) Among 14 patients with ILPC, 13 (92.9%) patients had unilateral ILPC, the rate of ipsilesional impairment on caloric test, or oVEMP/cVEMP test or PTA ipsilesionally was 53.8% (7/13) in patients with unilateral ILPC. The causes of unilateral ILPC were vertigo/dizziness of unclear origin (38.5%), labyrinthine infarction (15.4%), vestibular migraine (15.4%), and other diseases (30.8%); (2) among 21 patients with ULPC, 7 patients (33.3%) were accompanied with horizontal semicircular canal hypofunction ipsilesionally, the abnormal rate of caloric test, or oVEMP/cVEMP tests or PTA ipsilesionally was 57.1%. The causes of ULPC were vertigo/dizziness of unclear origin (33.3%), autoimmune inner ear disease (14.3%), labyrinthine infarction (14.3%), vestibular neuritis (9.5%), vestibular migraine (9.5%), and other diseases (19.0%); (3) among two patients with BLPC, one patient presented with unsteadiness, the causes of BLPC were vestibular paroxysmia and autoimmune inner ear disease.Conclusion: vHIT is a fast and effective method for assessing LPC, which can be used to detect isolated PC dysfunction. The causes of ILPC were peripheral origin or central origin. Patients with ILPC and ULPC mostly presented with dizziness/vertigo, and ULPC was often accompanied by ipsilateral vestibulo-cochlear impairment.

The Relationship

Abstract Background: The purpose of the study is to assess the vestibular and oculomotor function in patients with vestibular migraine(VM).And we also investigate the relationship between test resultsandeffectiveness of prophylactic medication.Methods: We recruited 41 patientswith VM. They were examinedwith vestibular-evoked myogenic potentials(VEMP), video head impulse test(vHIT) and videonystagmography(VNG), including spontaneous or positional nystagmus, gaze-evoked nystagmus, smooth pursuit and caloric irrigation testing.All VM patients were treated withprophylactic medications. Theintensity of vertigo were evaluated with dizziness handicap inventory(DHI) before and after treatment. After 6 months, we evaluate the effectiveness of prophylactic medication. We analyzed the relationship between test resultsandeffectiveness of prophylactic medication.Results:In vestibular function test,71% of VM patients showed abnormal result. 20% showed abnormal air-conducted cVEMP and 42% showed abnormal air-conducted oVEMP. 32% showed abnormal vHIT and 56% showed abnormal caloric irrigation test.The abnormal rate of oVEMP was significantly higher than cVEMP (p<0.05). And the abnormal rate of caloric irrigation test was significantly higher than vHIT(p<0.05). In oculomotor function test, 42% showed pathological result. The abnormal rate of oculomotor function test was significantly lower than vestibular function test (p<0.05). After 6 months follow-up, rate of good effectiveness was significantly higher in normal vestibular function test group compared with the abnormal vestibular function test group (p<0.05). Rate of good effectiveness was no statistically significant difference between normal oculomotor function test group and abnormal oculomotor function test group (p>0.05).Conclusions: Abnormal vestibular and oculomotor function are commonly observed in VM patients. And VM patients with abnormal vestibular function have a weak effectiveness of prophylaxis medications.

Test Profiles

To describe clinical, oculographic and vestibular test profiles in patients with vestibular migraine (VM) who presented with acute peripheral vestibulopathy. VM was diagnosed according to Bárány Society or Neuhauser criteria. Neuro-otological examination, video-head impulse tests (v-HIT), cervical and ocular vestibular-evoked myogenic potentials (cVEMP/oVEMP), subjective visual horizontal (SVH) and audiometry were undertaken. Ten patients presented with prolonged vertigo. All had primary position unidirectional horizontal spontaneous nystagmus (mean slow-phase velocity 9.6 ± 7.0°). Horizontal canal vestibulo-ocular reflex was reduced in all (mean gain 0.54 ± 0.2) with refixation saccades (cumulative amplitude 6.4 ± 3.2°). Abnormality rates for cVEMP, oVEMP and SVH were 30%, 80%, 78%, respectively. Magnetic resonance imaging brain was normal in all patients. Patients were followed up over 6 months to 8 years with no change in the final diagnosis. VM can rarely present as an acute peripheral vestibulopathy with findings that mimic vestibular neuritis and should be considered in the differential diagnosis of acute prolonged vertigo.
