鼻咽癌病人接受放疗时,除对鼻咽部和颈部转移的淋巴作一定放射量的照射外,还要对颈部未发现转移的部分进行照射。这样在放疗中和放疗结束后,鼻咽部和邻近的组织器官甚至局部皮肤,都会受到不同程度的损伤。因此,在放疗中和放疗后,必须采取一些自我保护措施来减少或减轻这些放射副反应。 一、口腔中有已经拔除的牙残根或金属齿冠,填补的龋齿等,均须待伤口愈合后,才能开始化疗,以预防放射线对病齿的破坏而引起放射性骨髓炎。
Radiotherapy for patients with nasopharyngeal carcinoma, in addition to the nasopharynx and neck lymph metastasis for a certain amount of radiation exposure, but also on the neck did not find the transfer of radiation. So in the radiotherapy and radiotherapy after the end of the nasopharynx and adjacent tissues and organs and even the local skin, will be varying degrees of damage. Therefore, during and after radiotherapy, some self-protection measures must be taken to reduce or mitigate these radiation side effects. First, the oral cavity has been removed tooth root or metal crown, fill the decayed teeth, etc., are required to be wound healing before chemotherapy can be started to prevent radiation damage to the teeth caused by radioactive osteomyelitis.
