Steroids for idiopathic sudden sensorineural hearing loss
The Cochrane Database of Systematic Reviews
|January 27, 2006
Summary
Steroids for sudden hearing loss show mixed results. One study found no benefit, while another indicated significant hearing improvement, but evidence remains unclear due to small patient numbers and study quality.
Area of Science:
- Otolaryngology
- Clinical Trials
- Evidence-Based Medicine
Background:
- Idiopathic sudden sensorineural hearing loss (ISSHL) is a sudden, unexplained hearing impairment.
- Steroid therapy is a common treatment for ISSHL, but its efficacy is debated.
- Lack of consensus exists regarding the effectiveness of steroids in treating ISSHL.
Purpose of the Study:
- To evaluate the effectiveness of steroid treatment for idiopathic sudden sensorineural hearing loss.
- To assess the side-effect profile associated with steroid use in ISSHL patients.
Main Methods:
- Systematic search of major medical databases (Cochrane, MEDLINE, EMBASE) and trial reference lists.
- Inclusion of randomized controlled trials comparing steroids with placebo or no treatment.
- Independent review of trials for eligibility and methodological quality assessment using the Cochrane approach.
Main Results:
- Only two low-quality randomized controlled trials met the inclusion criteria.
- One trial reported no significant hearing improvement with oral steroids compared to placebo.
- The second trial demonstrated a significant hearing improvement in 61% of patients receiving oral steroids versus 32% in the control group.
Conclusions:
- The effectiveness of steroids for idiopathic sudden sensorineural hearing loss remains uncertain due to contradictory findings.
- Limited evidence from small, low-quality trials hinders definitive conclusions.
- Further high-quality research is needed to clarify the role of steroids in ISSHL treatment.
