The Influence of Covid-19 on the Audio-vestibular System

Not Applicable

• Conditions: Covid19

• Registration Number: NCT04709146
• Lead Sponsor: HaEmek Medical Center, Israel

Brief Summary

the study's porpuse is to examine whether Covid-19 causese a reduction in sensorineural hearing and vestibular function in recovered pateints - compared to healthy controls.

Both study groups will undergo audiometry, tympanometry, Video Head Impulse testing, Subjective Visual Vertigo testing and Video-Nystamography.

Previous audiometry results will also be aquired.

Primary Outcome Measures

Name	Time	Method
sensoneural hearing level - PTA	through study completion, an average of 1 year	PTA at each frequency will be compared between new and baseline audiogram for each group. Afterwhich - the average PTA decreament would be compared betwenn both groups - contrl and recovered COVID-19 patients

Secondary Outcome Measures

Name	Time	Method
vestibular function	through study completion, an average of 1 year	vestibular function will be compared netween the two groups after VHIT, SVV and VNG testing
