title: The use of acrylic resin oral prosthesis in radiation therapy of oral cavity and paranasal sinus cancer.
abstract: In radiation therapy of cancers of the oral cavity and the paranasal sinuses, the extent to which the tissues of the oral cavity are included in the radiation treatment portals will determine the severity of the oral discomfort during treatment. This will affect the nutritional status of the patients, and may eventually affect the total dose of radiation which the patients can receive for treatment of their cancers. In cooperation with the Maxillofacial Prosthetic Department, an acrylic resin oral prosthesis was developed. This prosthesis is easy to use and can be made for each individual patient within 24 hours. It allows for maximum sparing of the normal tissues in the oral cavity and can be modified for shielding of backscattered electrons from heavy metals in the teeth. We have also found that acrylic resin extensions can be built onto the posterior edge of post-maxillectomy obturators; this extension can be used as a carrier for radioactive sources to deliver radiation to deep seated tumor nodules in the paranasal sinuses.
