Vestibular function testing in the 21st century

Vestibular Assessment in patients with Myasthenia Gravis (MG) is challenging, as diagnostic evaluation requires good recording of eye movements. Reports on Vestibular Function Testing (VFT) in MG patients have been scant and it is arguable that VFT will have little clinical value in the MG population. A 75-year-old man, with late onset acquired autoimmune MG presented with dizziness for evaluation. He completed VFT with no significant abnormalities in all tests and was elated to have vestibular ruled out as a contributing factor to his dizziness and imbalance. However, his functional impairments were still addressed and managed regardless of the test results. MG is a heterogenous condition that may be well-controlled with treatment. Patients with dizziness can still be diagnostically evaluated to rule in or out a vestibular involvement and should not be precluded from VFT. Patients should also be assessed for their functional impairments and not based on symptom checklist and objective test results alone. Hence, patients with normal VFT results can still benefit from a hybrid of vestibular rehabilitation therapy (VRT) with focus on habituation.

Abstract Background We describe herein the case of a patient whose primary complaints were episodic vertigo and “depersonalization,” a sensation of detachment from his own body. Purpose This case study aims to further clinical knowledge and insight into the clinical evaluation of vertiginous patients with complaints of depersonalization. Research Design This is a case study. Data Collection and Analysis A retrospective chart review of vestibular function testing done on a vertiginous patient with complaints of depersonalization was performed. Results Vestibular function testing revealed absent cervical and ocular vestibular evoked myogenic potentials on the left side with normal vHIT or video Head Impulse Test, videonystagmography, and rotational chair results, suggesting peripheral vestibular impairment isolated to the left saccule and utricle. Conclusion The otolith end organ impairment explains the patient's postural deviation to the left side during attempts to ambulate. We recommend that clinicians should be attentive to patient complaints of depersonalization and perform vestibular evoked myogenic potential testing to determine whether evidence of at least a unilateral peripheral otolith end organ impairment exists.

Objectives: The aim of this study was to elucidate the frequency and characteristics of preoperative vertigo symptoms in patients who undergo cochlear implantation (CI), in order to differentiate them from CI-related symptoms. Methods: In a prospective observational study, 47 adult CI candidates were asked about vertigo problems on a questionnaire. A subdivision into 3 groups was done: Group A (probable otogenic vertigo), group B (possible otogenic vertigo), and group C (not otogenic vertigo). Horizontal semicircular canal function was measured. Patients with vertigo complaints were compared to patients without vertigo with regard to the presence of abnormal vestibular function findings. Results: Twenty-five patients (53%) reported preoperative vertigo problems. In 21 (84%), the patient's history suggested a probable (group A) or possible (group B) otogenic origin. Patients with vertigo more often had abnormal findings on vestibular function testing than did patients without vertigo. This difference, however, was not statistically significant. Conclusions: A considerable number of CI candidates have preoperative vertigo symptoms. These cannot be explained by horizontal semicircular canal function alone. In order to understand why CI patients develop postoperative vertigo, analysis of prospective preoperative vestibular function test findings and vertigo symptoms is necessary.
