The makers claim
The increased supply of oxygen to the ear and brain reduces the severity of hearing loss and tinnitus.
What is the treatment?
The person sits in a small airtight chamber, and air pressure is increased to three times higher than normal pressure for 60-120 minutes. Typical courses involve 20-40 sessions.
What are the downsides of this treatment?
This treatment is associated with some risk, including damage to ears, sinuses and lungs from the effects of pressure, temporary worsening of short-sightedness, claustrophobia and oxygen poisoning[1].
Cost, as treatment is only available privately.
Has there been research into this treatment?
Yes, including a Cochrane review[1].
What does the research say?
The significance of any improvement in tinnitus could not be assessed. There were no significant improvements in chronic tinnitus (tinnitus experienced for over six months)[1].
This therapy does not benefit patients with chronic tinnitus. There is no evidence to show whether this therapy benefits newly diagnosed patients.
Comments
More randomised, placebo-controlled, double-blind studies with large sample sizes are needed to confirm the effectiveness of hyperbaric oxygen therapy for tinnitus patients. Uniform, validated, tinnitus-specific questionnaires and measurement scales should be used in future studies.
