Summary

What Researchers Did

This study compared the effects of hyperbaric oxygen therapy administered once or twice daily, combined with naftidrofuryl, for sudden deafness.

What They Found

Researchers found that the efficiency and side effects of hyperbaric oxygen therapy were similar between the two groups receiving either one or two sessions per day. This was observed when combined with naftidrofuryl and steroids, and after preliminary normovolemic hemodilution.

Canadian Relevance

This study has no direct Canadian connection as it was conducted in a different healthcare context.

Study Limitations

A key limitation is the unknown origin and spontaneous recovery rate of sudden deafness, making it difficult to definitively claim treatment efficiency.
