Abstract
The validity of oral prosthetic stents for maxillofacial cancer during radiation therapy: Case report
Highlights
Radiation therapy (RT) is defined as the therapeutic use of ionizing radiation in the management of neoplasms of the organs without surgery, or after surgery as an adjunctive palliative treatment, either in combination with or without chemotherapy [1]
Various types of radiation stents have been applied such as radiation source carriers, perioral cone, radiation protection/shielding, position maintaining and tissue bolus [6]
Two types of customized intraoral stents were respectively fabricated for patients who were planned to RT due to maxillofacial cancer with the collaborations of surgeon, radiotherapist and prosthodontist
Summary
Radiation therapy (RT) is defined as the therapeutic use of ionizing radiation in the management of neoplasms of the organs without surgery, or after surgery as an adjunctive palliative treatment, either in combination with or without chemotherapy [1]. Though RT has increasingly been conducted as an adjunctive measure in the management of head and neck cancer currently, the adverse reactions of surrounding tissues are frequently occurred such as erythema, mucositis, ulcers, xerostomia, caries, or possible osteoradionecrosis on irradiated bone [2] These complications could diminish the quality of life, rehabilitation level, or might discourage the patient from acclimation to treatment process. Radiation prosthetic stents have been fabricated and tried to oral cancer patients as a tool of prevention [3] These stents are used to adjust the position or to shield tissues or to assist in the efficient administration of irradiation to the affected spots, which limit the post therapy morbidity [4,5]. Ventilation holes were made to facilitate the respiration during RT followed by PMMA stent curing (Figure 6B)
