Summary
Thyroid dysfunction, particularly abnormal T3 levels, is common in sudden sensorineural hearing loss (SSHL) patients. These thyroid issues impact SSHL onset age and hearing recovery, suggesting T3 screening aids prognosis.
Area of Science:
- Otolaryngology
- Endocrinology
- Internal Medicine
Background:
- Sudden sensorineural hearing loss (SSHL) is unexplained hearing loss.
- Systemic diseases impact SSHL occurrence and outcomes.
- Thyroid hormone is crucial for auditory development, but its role in SSHL is unstudied.
Purpose of the Study:
- Investigate thyroid dysfunction prevalence in SSHL patients.
- Analyze the impact of thyroid dysfunction on SSHL occurrence.
- Determine the relationship between thyroid dysfunction and SSHL hearing outcomes.
Main Methods:
- Retrospective analysis of 676 SSHL patients.
- Detailed description of thyroid function distribution.
- Statistical analysis of thyroid dysfunction and hearing outcomes.
Main Results:
- 24.41% of SSHL patients had abnormal thyroid function.
- Younger onset age in patients with abnormal FT3 levels.
- Lower T3 levels correlated with poorer hearing recovery, especially after 14 days.
Conclusions:
- Thyroid dysfunction is more prevalent in SSHL than the general population.
- T3 and FT3 levels are linked to SSHL onset and hearing outcomes.
- Early thyroid screening, especially T3, may improve SSHL prognosis assessment.
