What Researchers Did
Researchers reviewed medical charts of 49 adult patients with idiopathic sudden sensorineural hearing loss (SSNHL) who received hyperbaric oxygen therapy within 72 hours of symptom onset, without corticosteroids, to assess hearing improvement.
What They Found
Of 49 patients, 35 (71.4%) experienced complete hearing recovery after hyperbaric oxygen therapy. The mean hearing threshold significantly improved from 69.8 dB to 31.4 dB (p<0.001). No significant differences in recovery were observed based on sex, affected ear, or initial hearing loss grade.
What This Means for Canadian Patients
This study suggests hyperbaric oxygen therapy could be an effective alternative for Canadian patients with sudden sensorineural hearing loss who cannot take corticosteroids. It offers a potential treatment option for a time-sensitive condition, aiming to improve hearing outcomes.
Canadian Relevance
This study was not conducted in Canada and does not involve Canadian participants or healthcare systems.
Study Limitations
This preliminary study is limited by its retrospective design and the absence of a control group receiving conventional corticosteroid treatment.
