Cancer of Head and Neck

Clinical Trial – Hyperbaric Oxygen and Its Effect on Radiation Induced Long Term Side Effects

The investigators intend to determine if patients that are already undergoing Hyperbaric
Oxygen (HBO) therapy one year post treatment with radiation therapy for head and neck cancer,
experience improvement in xerostomia and/or taste alteration. The investigators will enroll a
similar demographic one year post treatment with radiation therapy that does not receive HBO
therapy. This is a quality of life study.
