M, male; F, Female; P, Prospective; R, Retrospective; C, Cross-sectional; U, Unilateral; B, Bilateral; D, Tests performed at diagnosis or within 15 days; cVEMP, Cervical vestibular evoked myogenic potential; oVEMP, Ocular vestibular evoked myogenic potential;
Number of ears with altered cVEMP (%)/total tested ears.
Number of ears with altered oVEMP (%)/total tested ears.
Ears that showed auditory recovery in relation to affected ears – moment (in months) of final audiometric evaluation.
Until 2011, the study used data from retrospective analysis, when it became prospective.
2 patients underwent tests between 31–49 days after diagnosis and not on the day of diagnosis.
Performed after several weeks (unspecified).
