What Researchers Did
Researchers conducted a rapid systematic review to evaluate the effect of hyperbaric oxygen therapy on hearing thresholds in patients with recent acute acoustic trauma.
What They Found
They identified six original research papers, but their weak methodology and profound differences prevented data pooling. Mean hearing recovery ranged from 17 to 47 dB in hyperbaric oxygen groups compared to 5 to 46 dB in control groups, leading to an unclear conclusion regarding the therapy's overall effect.
What This Means for Canadian Patients
For Canadian patients experiencing acute acoustic trauma, the current evidence does not definitively support or refute the use of hyperbaric oxygen therapy for hearing recovery. Patients should discuss all available treatment options and their uncertainties with their healthcare providers.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The primary limitation was the weak methodology and significant heterogeneity of the included studies, preventing data pooling and a clear conclusion.
