We evaluated the evolution of mouth opening before and after radiotherapy of the head and neck in patients using intraoral stents.
Twenty-one patients with head and neck cancer who were indicated for radiotherapy participated in this study. Maximum interincisal opening measurements were performed before and after radiotherapy. Paired analyses of the pre- and post-radiotherapy groups were performed using paired samples t-tests and correlation analyses using Spearman's correlation test, with p < 0.05 considered statistically significant.
Paired analyses of the pre- and post-radiotherapy groups revealed a statistically significant reduction in post-radiotherapy maximum interincisal opening (p < 0.001). However, only four individuals were diagnosed with trismus after radiotherapy. Regarding the correlation tests, no statistically significant differences were observed between the differences in pre- and post-radiotherapy maximum interincisal opening values and the study variables.
The use of prosthetic devices during head and neck radiotherapy can reduce radiation doses in areas of no interest, thereby preventing the acute and late toxicities associated with cancer therapy.
我们评估了使用口腔内支架的患者在头颈部放疗前后张口度的变化情况。
21名头颈部癌症患者参与了本研究，这些患者均需接受放疗。在放疗前后分别测量最大切牙间开口度。对放疗前后两组数据进行配对分析，采用配对样本t检验，并用Spearman相关检验进行相关性分析，p < 0.05被认为具有统计学意义。
放疗前后两组的配对分析显示，放疗后最大切牙间开口度有统计学意义的降低（p < 0.001）。然而，放疗后仅4人被诊断为牙关紧闭。关于相关性检验，放疗前后最大切牙间开口度值的差异与研究变量之间未观察到统计学显著差异。
在头颈部放疗期间使用修复装置可减少非靶区的辐射剂量，从而预防与癌症治疗相关的急慢性毒性反应。
