What Researchers Did
Researchers compared the effectiveness of hyperbaric oxygen comprehensive therapy versus simple hyperbaric oxygen treatment in 220 construction workers with noise-induced deafness.
What They Found
The comprehensive therapy group showed a higher cure rate of 53.6% compared to 38.2% in the simple hyperbaric oxygen group. The total effective rate was also significantly higher for comprehensive therapy at 79.1% versus 67.3%, and improved further with more treatment courses, reaching 60.9% cure rate and 84.5% total effective rate after four courses.
Canadian Relevance
This study was conducted outside of Canada and does not have a direct Canadian connection.
Study Limitations
The study was conducted at a single hospital with a specific population of construction workers, which may limit the generalizability of the findings.
