An observational study in SSNHL(Sudden Sensory Neural Hearing Loss), Sudden Hearing Loss and Hearing Loss, Idiopathic Sudden Sensorineural, sponsored by Wonju Severance Christian Hospital. Recruiting at 1 site in Korea, Republic of. Open to participants aged 20 Years to 100 Years. Per ClinicalTrials.gov, last updated 2025-03-26.
Sponsored by Wonju Severance Christian Hospital · Observational
This study is to build a cohort of sudden sensorineural hearing loss (SSNHL) patients. When the patient visited the Department of otolaryngology clinic for hearing loss, we can diagnose the SSNHL following the result of pure tone audiometry and the history of the patient. The cohort is a system that tracks the hearing recovery status, timing, and degree of recovery of patients who received cocktail therapy with or without high-dose steroids, vasodilators, antiviral agents, and intratympanic steroid injections, satellite ganglion block, and hyperbaric oxygen therapy.
66 studies on the registry are indexed under Hearing Loss, Sudden; 25 are open to participants now.
This study's planned enrollment of 1,000 is above the median of 82 across 14 observational studies indexed under Hearing Loss, Sudden.
