What Researchers Did
Australian family medicine physicians reviewed the latest evidence and guidelines on how to diagnose and treat sudden sensorineural hearing loss (SSNHL), including HBOT as an emerging option.
What They Found
High-dose corticosteroids remain the first-line treatment and must be started quickly. Intratympanic steroid injections and HBOT are identified as additional therapies that may improve hearing recovery, particularly in patients who do not fully respond to oral steroids alone.
What This Means for Canadian Patients
Sudden hearing loss is a medical emergency, and Canadian patients who experience it should go to an emergency department immediately, delays reduce recovery chances. HBOT is not widely available across Canada for this indication and is not OHIP-covered, but patients with incomplete steroid response may want to ask their ENT specialist about it as an adjunct option.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This is a clinical review, not a new trial, so it does not generate new outcome data and relies on the strength of pre-existing evidence, which varies in quality.
