Comparison of Recovery Rates of Sudden Sensorineural Hearing Loss by Age Group.

Background: While numerous studies have been conducted on sudden sensorineural hearing loss (SSNHL), research on how treatment outcomes and prognosis vary by age remains insufficient. This study aims to investigate the differences in recovery rates among SSNHL patients divided by age groups. Methods: A retrospective study was conducted on 177 patients diagnosed with SSNHL from 2020 to 2023. The patients were categorized into four age groups: under 20, 30-40, 50-60, and over 70. Recovery rates and associated symptoms were compared across these groups. Results: Significant recovery rates were observed in all age groups except for those over 70 ( p = 0.006, p = 0.003, p = 0.009). No significant differences were found in recovery rates based on gender ( p > 0.75) or symptoms such as tinnitus, ear fullness, and dizziness ( p > 0.05). Conclusions: The study revealed that younger and middle-aged adults showed statistically significant improvements in recovery rates, while the elderly exhibited relatively lower recovery rates.
