Radionecrosis of the larynx is a delayed effect of radiation therapy and it is a debilitating disease associated with pain, dysphagia (difficulty swallowing), respiratory obstruction, and, in some cases, the need for laryngectomy. Persistent poor wound healing can lead to death. It is very rare, but morbidity and mortality rates are high if left untreated.
Even with conventional therapy involving prolonged use of antibiotics, steroids, and surgical intervention; there is still a high risk in the radiated tissues, which may lead to a hypoxic environment increasing chances of failure due to the high concentrations of bacteria.
When used in conjunction with these therapies, HBO has been shown to improve healing potential, decrease inflammation, and due to bacteriostatic properties of concentrated oxygen, reduce harmful bacterial environment associated with necrosis.
Hyperbaric chambers allow us to deliver high doses of oxygen under pressure. By placing the patient in FDA approved HBO chambers we are able to increase normobaric (atmospheric) air, which contains approximately 21% oxygen, to an available 5x (approximately) greater dose with 100% oxygen which is compressed in the chamber to treatment dose of 2.0 -2.4 ATA bringing dose to approximately 1000% oxygen availability to hypoxic tissues.
Since Oxygen is a drug, we will need a prescription for a CONSULT FOR HYPERBARIC OXYGEN THERAPY. This pre-screen physical must be completed prior to starting hyperbaric oxygen therapy.
