Hyperbaric Oxygen Therapy (HBOT)

Hyperbaric oxygen therapy (HBOT) has been proposed as a treatment for tinnitus that frequently accompanies hearing loss. In a large analysis of all the published studies on this topic, Bennett and colleagues (2005) evaluated the safety and effectiveness of hyperbaric oxygen therapy (HBOT) for the treatment of sudden hearing loss and tinnitus.


An example of a hyperbaric oxygen therapy device used for tinnitus therapy studies is seen above.

In a single trial, 50 subjects were assessed for improvement in hearing and tinnitus after treatment with Hyperbaric oxygen therapy. Despite reporting improvement in hearing, the significance of any improvement in a subjective rating of tinnitus following Hyperbaric oxygen therapy could not be assessed due to poor reporting. The authors concluded that due to the small study population, methodological shortcomings, and the poor reporting, there is a lack of clinical evidence of a "beneficial effect" of hyperbaric oxygen therapy in the treatment of tinnitus.  (Bennett, 2005).

Advantages of Hyperbaric Oxygen Therapy for tinnitus treatment


Disadvantages of Hyperbaric Oxygen for tinnitus therapy

It requires multiple daily treatments for several weeks
It is very expensive ($2000-$3000) for whole duration of therapy
Not effective

For an effective alternative, there now exists a web-based customized sound therapy of tinnitus inspired by technology developed by Dr. Djalilian from University of California Irvine.  For this breakthrough research-based tinnitus therapy click here.
