What this trial studies

This observational study aims to create a cohort of patients diagnosed with sudden sensorineural hearing loss (SSNHL) at Wonju Severance Christian Hospital. Patients will be evaluated based on their hearing loss diagnosis confirmed through pure tone audiometry and will be monitored for their recovery status, timing, and degree of recovery. The study will track patients who receive various treatments, including cocktail therapy with or without steroids and other interventions. The goal is to gather data that may help understand the recovery patterns in SSNHL patients.

Who should consider this trial

Good fit: Ideal candidates are adults over 20 years old diagnosed with sudden hearing loss of 30dBHL or more within three days.

Not a fit: Patients with suspected inner ear diseases or those who do not consent to participate may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of treatment efficacy and recovery patterns in patients with sudden sensorineural hearing loss.

How similar studies have performed: While there have been studies on SSNHL, this cohort approach focusing on recovery tracking is relatively novel.
