What Researchers Did
Researchers conducted a systematic review and meta-analysis of 14 randomised controlled trials involving 794 participants to evaluate hyperbaric oxygen therapy (HBOT) combined with systemic corticosteroids for sudden sensorineural hearing loss (SSNHL).
What They Found
The combined therapy of hyperbaric oxygen therapy and systemic corticosteroids significantly improved low-frequency hearing thresholds (SMD: 0.83, 95% CI: 0.66-1.00, p < 0.0001). This combination also increased the odds of complete hearing recovery by more than twofold (OR: 2.05, 95% CI: 1.41-2.98, p = 0.0002).
What This Means for Canadian Patients
Canadian patients experiencing sudden sensorineural hearing loss may benefit from hyperbaric oxygen therapy as an adjunct to standard corticosteroid treatment. This combined approach could lead to better hearing recovery and improved quality of life compared to corticosteroids alone.
Canadian Relevance
This study did not include any Canadian participants or researchers, and no Canadian data were analyzed.
Study Limitations
The abstract indicates that significant limitations were present, which could include heterogeneity among the included studies or potential publication bias.
