OBJECTIVES
This article demonstrates a new method of making a spacer that increases the distance between the mandible and implanted radioactive sources in interstitial brachytherapy for patients with mobile tongue cancer.
STUDY DESIGN
Fifty-three patients with mobile tongue cancer underwent interstitial brachytherapy with spacers made by this new technique.
RESULTS
Our spacer is not difficult to create or to use. The spacer was made from a plastic splint by using thermoforming techniques and quick self-curing resin, which did not need waxing, wiring, or casting. The surface of the spacer, which comes in contact with the tongue, is smooth because it is covered with tissue-conditioning material. There were no complaints of pain from the patients. Osteoradionecrosis of the mandible developed in only 1 (1.9%) of these patients.
CONCLUSIONS
This spacer is simple to make and prevented osteoradionecrosis.
目的
本文展示了一种制作间隔物的新方法，该方法可增加可移动舌癌患者间质近距离放射治疗中下颌骨与植入放射性源之间的距离。
研究设计
53例可移动舌癌患者接受了采用这种新技术制作的间隔物进行的间质近距离放射治疗。
结果
我们的间隔物制作和使用并不困难。该间隔物由塑料夹板通过热成型技术和快速自固化树脂制成，无需上蜡、布线或铸造。与舌头接触的间隔物表面光滑，因为它覆盖有组织调理材料。患者没有疼痛主诉。这些患者中仅1例（1.9%）发生了下颌骨放射性骨坏死。
结论
这种间隔物制作简单，可预防放射性骨坏死。
