木塞支撑加张口功能锻炼预防鼻咽癌放疗后张口困难

Wood-stopper to prop add the Mouth open training for prevention of trismus in nasopharyngeal carcinoma patients being treated with radiotherapy

目的：探讨木塞支撑加张口功能锻炼对鼻咽癌患者放疗后张口困难的防治效果。方法：63例经病理确诊为鼻咽癌的患者随机分为研究组和对照组，研究组32例放疗开始即在医护人员的指导下进行木塞支撑加有一定强度的张口功能锻炼；对照组31例没有规定张口强度，仅行一般张口功能锻炼。在放疗前、放疗结束后1月和以后的每3～6月对组患者分别观察门齿距的变化。结果：研究组放疗后张口缩小的程度明显低于对照组，分别为0．47±0．94cm、1．16±0．83cm，（P〈0．01）。结论：在鼻咽癌患者接受放射治疗的同时，行木塞支撑加张口功能锻炼能有效预防放疗所致的张口困难。

Objective： To analyze the role of mouth open training for prevention of trismus in nasopharyngeal carcinoma pa- tients treated undergoing radiotherapy. Methods： 63 patients in pathology proven nasopharyngeal carcinoma were randomly divided into two groups： researoh group and control group. 32 patients in research group had acceped Wood - stopper to prop and the Mouth open functional exercises. 31 patients in control group only had acceped ordinary exercises of opening mouth. Before radiotherapy and 1 month after treatment and each 3 - 6 months thereafter observe the variety of fore - tooth distance. Results： The reduction of the distance between the incisors were（0.47±0.94cm） in the training group in contrast to the（ 1.16±0.83cm）in control group （P 〈 0.01 ）. Conclusions：It is true that Wood - stopper to prop add good functional mouth open training is able to lower the incidence and these verity of trismus in NPC patients treated with radiotherapy From the beginning of the radiotherapy to the end, Good guidance and supervision is necessary.
