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.
