What Researchers Did
This study reviewed over 100 publications, including eight randomised controlled trials, to evaluate hyperbaric oxygen therapy for idiopathic sudden sensorineural hearing loss.
What They Found
Researchers found that hyperbaric oxygen therapy, when initiated within two weeks of symptom onset and combined with corticosteroids, yielded the best results. Patients experienced an average hearing gain of 19.3 dB for moderate hearing loss and 37.7 dB for severe cases, moving deficits from moderate/severe to slight/no impairment.
