摘　　要：目的分析头颈部恶性肿瘤在放疗过程中,面罩体位固定技术临床应用价值及存在的问题。方法随机抽取实施头颈部放疗患者288野次,其中使用头颈面罩固定体位的136野次,使用非头颈面罩固定体位的152野次,在放疗摆位照射实施前、后用游标卡尺测量照射野中心点的移动情况进行比较。结果面罩体位固定组照射野中心偏移范围为(1.09±0.41)mm,而非面罩体位固定组为(2.99±0.60)mm,两组数据差异有统计学意义(P<0.01)。结论使用面罩固定组的照射野中心偏移范围明显小于非面罩体位固定组。Objective To analyze the problems and clinical value of mask-fixed method in radiotherapy of head and neck tumor. Methods To take out 288 fields in radiotherapy courses of patients with head and neck tumor, there were 136 fields with mask-fixed method and 152 fields without mask-fixed method. Measured the moved bias of the fields center point by vernier caliper at the time of pro-irradiation and post-irradlation. Results the moved bias range of fields with mask-fixed method were （ 1.09 ±0.41 ） mm and the bias range of fields without mask-fixed method were （2.99 ±0.60） mm there was a significant statistical difference in two groups （P〈0.01）. Conclusions The bias range of fields with mask-fixed method were very smaller than that without mask-fixed method.
