Frequently Asked Questions
Is HBOT FDA/UHMS-approved for Sudden hearing loss?
Yes. Idiopathic Sudden Sensorineural Hearing Loss is one of the indications approved by the Undersea & Hyperbaric Medical Society, and hyperbaric oxygen therapy for it is generally eligible for insurance coverage when criteria are met.
What pressure and how many sessions does Sudden hearing loss typically need?
Standard-of-care protocols typically run at 2.0–2.5 ATA for about 10–20 sessions. Your physician sets the exact protocol based on your case.
How does hyperbaric oxygen help with Sudden hearing loss?
Hyperbaric oxygen raises oxygen tension in the poorly-vascularized cochlea, where standard delivery is limited.
How many directory centers list Sudden hearing loss?
39 centers in our directory report treating Sudden hearing loss, of which 9 are UHMS-accredited. Always confirm directly with the center.
