Vestibular Prognosis Assessment of ISSNHL With Vestibular Dysfunction Treated With Oral or Intratympanic Glucocorticoids

Summary

Idiopathic sudden sensorineural hearing loss (ISSNHL) is a complicated hearing impairment with unclear etiology and unsatisfying treatment effects. Vestibular dysfunction like vertigo has been considered as a risk factor of profound hearing loss and poor prognosis in ISSNHL. Glucocorticoids, administered through oral or intratympanic way, is currently a regular and standard treatment for ISSNHL based on hearing outcome. However, little investigations have been conducted on recovery process and treatment effects of glucocorticoids on vestibular dysfunctions of ISSNHL. This study aims to evaluate the recovery pattern and possible process of vestibular system in ISSNHL with vestibular dysfunction, and to compare the efficacy of oral or intratympanic glucocorticoids in these participants. A randomized, outcome assessor- and statistical analyst-blinded, controlled, clinical trial will be carried out. 72 patients complaining of vestibular dysfunction appearing as vertigo, dizziness, imbalance or lateropulsion with ISSNHL will be recruited and randomized into two arms of oral or intratympanic glucocorticoids therapy in 1:1 allocation. The primary outcomes will be subjective feelings evaluated by duration of vestibular dysfunction symptoms, dizziness-related handicap, visual analogue scale for vertigo, and objective vestibular function tests results assessed by sensory organization test, caloric test, video head impulse test and vestibular evoked myogenic potentials. Assessment will be performed at baseline and at 1, 2, 4, and 8 weeks post-randomization.
