Clinical Trial Summary

Idiopathic sudden sensorineural hearing loss (ISSNHL) refers to idiopathic sensorineural hearing loss of at least 30 dB over at least three test frequencies occurring over a 72-hour period. Vertigo has been considered a risk factor of poor prognosis in patients with ISSNHL. However, the clinical outcome and development of vestibular function in these patients have not been reported yet. We'd like to conduct a study on the problem whether these patients resulted in a complete recovery of the peripheral vestibular functions or compensation of the central vestibular system. If the answer is the former one, these cases might be supportive evidence of regeneration of hair cells in vestibular disorders.


Clinical Trial Description

This study is designed as a prospective cohort study with only one cohort. Enrolment and data collection are performed by trained research staff who are not involved in the care of the patients. The primary measurement is the vestibular function tests including SOT, the caloric reflex test, vHIT, VEMP (cVEMP and oVEMP). The secondary measurements included PTA, DHI, and VAS. The sample size was set at 60 patients. The continuous variables were expressed as means ± standard deviation (SD) whereas categorical variables were expressed as frequency and percentage for data description. P <0.05 was considered statistically significant. ;
