What Researchers Did
Researchers evaluated the effectiveness of primary hyperbaric oxygen treatment (HBOT) in 59 patients with idiopathic sudden sensorineural hearing loss (ISSNHL) by comparing hearing thresholds before and after treatment.
What They Found
Patients experienced significantly lower hearing thresholds after hyperbaric oxygen treatment compared to pre-treatment values (P < 0.001), with a median recovery of 22.5 dB. Significant improvements were observed at 500, 1,000, 2,000, and 4,000 Hz (P < 0.001), with the greatest recovery of 32 dB at 1,000 Hz.
What This Means for Canadian Patients
Canadian patients with idiopathic sudden sensorineural hearing loss may consider hyperbaric oxygen treatment as a primary option, especially if corticosteroid therapy is contraindicated. This could offer an alternative for those seeking treatment, provided HBOT facilities are accessible.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is its relatively small sample size of 59 patients and the absence of a comparative control group.
