Does hyperbaric oxygen therapy work better than steroids for sudden hearing loss?
Sudden sensorineural hearing loss is a medical emergency where the inner ear stops working suddenly. Standard treatment usually involves steroids to reduce swelling. Recent research suggests adding hyperbaric oxygen therapy to this standard steroid treatment can improve outcomes. This combination approach appears to help more people regain hearing compared to using steroids by themselves.
What the research says
A 2025 study of 505 patients found that those receiving both steroids and hyperbaric oxygen therapy had significantly better hearing improvement than those taking steroids alone. Specifically, the combined group showed higher response rates and was 2.5 times more likely to achieve substantial hearing recovery 4. The study noted that starting treatment within 11 days of diagnosis produced the best results 4.
Another review supports this by stating that combining hyperbaric oxygen therapy with corticosteroids showed the strongest support for enhancing hearing recovery 3. This combination targets vascular disruptions in the inner ear that cause the sudden loss 3. However, the review notes that effectiveness depends on factors like how quickly treatment begins and the initial severity of the hearing loss 3.
Research also highlights that hyperbaric oxygen therapy is particularly effective for patients with hearing loss at lower frequencies 4. A machine learning model analyzing severe cases identified the number of hyperbaric oxygen sessions as a key predictor of recovery, suggesting that a sufficient number of sessions is important for success 5.
What to ask your doctor
- How soon after my diagnosis should I start hyperbaric oxygen therapy for the best results?
- What is the recommended number of hyperbaric oxygen sessions for my specific case?
- Is my initial hearing loss pattern, particularly at lower frequencies, a factor in whether this therapy will help?
- Are there any specific risks or side effects I should know about when combining this therapy with steroids?
