title: Devices valuable in head and neck radiotherapy.
abstract: Normal tissue reactions limit the use of radiotherapy in the management of patients with head and neck neoplasms. Customized intraoral stents can help prevent unnecessary irradiation of various normal tissues thus reducing severity of reactions. Two basic types of devices, referred to as shielding and positional stents, are presented. The fabrication and the application of such devices are illustrated through five case reports. Recommendations on use of these tools and the possibility of combining these means with methods to improve dose distribution within the target volume containing air gaps are provided. Close collaboration between the attending radiotherapist and dentist is essential for designing appropriate devices for individual patients. However, when properly designed and used, these stents are effective in reducing treatment morbidity.
