(CS-005) Using Non Contact Near Infrared Spectroscopy Studies to evaluate the effectiveness of Hyperbaric Oxygen Therapy using the Marx Protocol

Introduction: Hyperbaric Oxygen therapy has been used to treat osteoradionecrosis of the mandible using the Marx Protocol prior to tooth extraction. The established protocol implementing 20 initial hyperbaric oxygen treatments at 2.4 ATA followed by 10 additional sessions of hyperbaric oxygen therapy after tooth extraction has been routinely used.

Near infrared spectroscopy was used to capture imaging of the patient's mouth before and after hyperbaric oxygen to prove effectiveness of hyperbaric oxygen

Methods: Non Contact Near Infrared Spectroscopy imaging was taken of the patient's face (both outside and inside of the mouth) as well as the anterior neck

Results: Non Contact Near Infrared Spectroscopy showed improvement of microcirculation and oxygenation of the soft tissues of the gums after hyperbaric oxygen therapy.

Discussion: This expands how non contact near infrared spectroscopy can be used to objectively measure the effectiveness of hyperbaric oxygen therapy with head and neck cancer patients that have been treated with radiation.
