Conformal or intensity-modulated radiation therapy can be improved by using a customized tongue-displacing (CTD) stent. These stents are designed to either move healthy oral tissues out of the path of the radiation beam or stabilize mobile tissues to allow more precise field control.
The authors describe CTD stent construction for both tongue-deviating and tongue-depressing applications.
CTD stents enable clinicians to achieve more predictable and consistent radiation dosimetry planning while sparing greater volumes of healthy tissue from damage. They have been well tolerated by patients.
Use of CTD stents results in increased oral mucosal sparing, ensures reproducible immobilization and is incorporated readily into the clinical practice of radiation oncology. Practical Implications. Clinicians can reduce or avoid significant morbidity to healthy oral tissues by using CTD stents. This can lead to better outcomes and improved quality of life for patients receiving head and neck radiation therapy.
定制式舌移位（CTD）支架可改善适形或调强放疗。这些支架的设计目的是将健康的口腔组织移出射线束路径，或稳定移动的组织以实现更精确的野控制。
作者描述了用于舌偏斜和舌压低的 CTD 支架构造。
CTD 支架使临床医生能够在保护更大体积健康组织免受损伤的同时，实现更可预测和一致的放射剂量规划。患者对其耐受性良好。
使用 CTD 支架可增加口腔黏膜的保护，确保可重复的固定，并易于纳入放射肿瘤学的临床实践。实际意义。通过使用 CTD 支架，临床医生可以减少或避免健康口腔组织的显著发病率。这可以为接受头颈部放疗的患者带来更好的结果和更高的生活质量。
