Summary
This study found a significant association between statin use and sudden sensorineural hearing loss (SSNHL). Previous statin users had a higher risk of developing SSNHL compared to non-users.
Area of Science:
- Otolaryngology
- Cardiovascular Pharmacology
Background:
- Sudden sensorineural hearing loss (SSNHL) is a complex condition with various potential contributing factors.
- The role of lipid-lowering medications, such as statins, in the development of SSNHL has not been previously investigated.
Purpose of the Study:
- To investigate the association between statin use and the incidence of sudden sensorineural hearing loss (SSNHL).
- To explore the relationship between regular and irregular statin use and SSNHL risk.
Main Methods:
- A population-based case-control study was conducted using the Taiwan Longitudinal Health Insurance Database.
- 1263 cases of SSNHL (aged ≥40 years) were matched with 6315 controls.
- Conditional logistic regression was employed to analyze the association between statin use and SSNHL, adjusting for relevant covariates.
Main Results:
- A significantly higher prevalence of statin use was observed in SSNHL cases (27.2%) compared to controls (21.3%).
- Statin use before the index date was associated with an increased odds ratio (OR) of 1.36 for SSNHL.
- Both regular (OR=1.30) and irregular (OR=1.49) statin use showed a significant association with SSNHL.
Conclusions:
- Sudden sensorineural hearing loss (SSNHL) is significantly associated with previous statin use.
- The findings suggest a potential link between statin therapy and the risk of developing SSNHL.
