Sudden sensorineural hearing loss is associated with chronic rhinosinusitis: population-based study.

Area of Science:

• Otolaryngology
• Epidemiology
• Public Health

Background:

• Chronic rhinosinusitis (CRS) is a common inflammatory condition.
• Sudden sensorineural hearing loss (SSNHL) is an otologic emergency with various potential causes.
• The relationship between CRS and SSNHL requires further investigation.

Purpose of the Study:

• To investigate the association between a prior diagnosis of chronic rhinosinusitis and the occurrence of sudden sensorineural hearing loss.
• To explore potential age-related differences in this association.

Main Methods:

• A population-based retrospective cohort study design was employed.
• Data were extracted from the Taiwan Longitudinal Health Insurance Database 2000.
• Conditional logistic regression analysis was used to determine odds ratios for CRS in SSNHL cases versus controls.

Main Results:

• A statistically significant association was observed between prior chronic rhinosinusitis and sudden sensorineural hearing loss (OR = 1.36, 95% CI = 1.16-1.60).
• The association was notably stronger in younger patients (≤44 years) (OR = 2.18, 95% CI = 1.63-2.92).
• This significant relationship was not observed in older patients (>60 years).

Conclusions:

• Chronic rhinosinusitis may be a risk factor for developing sudden sensorineural hearing loss.
• Younger individuals with CRS appear to have a heightened risk of SSNHL.
• Further research is warranted to elucidate the underlying mechanisms connecting CRS and SSNHL.
