Summary

What Researchers Did

Researchers reported on two patients with idiopathic sudden sensorineural hearing loss (ISSHL) who received adjunctive hyperbaric oxygen therapy (HBO2) and steroid injections.

What They Found

Both patients, treated with a standard 2.4 atmospheres absolute (atm abs) 90-minute HBO2 protocol, showed positive outcomes. They experienced significantly improved scores in both speech reception and speech discrimination.

Canadian Relevance

This study has no direct Canadian connection as it was not conducted in Canada, nor does it involve Canadian researchers or patients.

Study Limitations

A significant limitation of this study is its design as a case report involving only two patients, which severely limits the generalizability of the findings.
