目的探索鼻咽癌放疗患者腮腺血流情况与口干程度的关系,分析B超检测腮腺血流在评价鼻咽癌放疗患者口干程度临床应用的合理性。方法 2013年5月—2014年12月对30例鼻咽癌患者进行腮腺血流的B超检测,通过“涎腺急性放疗损伤评估表”记录患者的口干程度,分析鼻咽癌放疗患者腮腺血流情况与口干程度的关系。结果放疗后3个月患者的口干程度平均水平较放疗中明显降低,差异均具有统计学意义(P<0.05),放疗前、中、后PSV、EDV、RI比较差异有统计学意义(P<0.05)。结论 B超对检测放射疗法对腮腺功能损害程度有一定的参考价值,但定量的分析腮腺功能的受损情况等还有待进一步深入的研究。
Objective To explore the relationship between the parotid gland flow and the degree of dry mouth in patients with nasopharyngeal carcinoma radiotherapy and to analyze the rationality of B-mode parotid blood flow in assessing the degree of dry mouth of patients with nasopharyngeal carcinoma radiotherapy. Methods From May 2013 to December 2014, 30 patients with nasopharyngeal carcinoma were examined by B ultrasound examination of parotid blood flow. The degree of dry mouth of the patients was recorded by “Salivary Gland Acute Radiotherapy Injury Evaluation Table” Relationship between parotid blood flow and dry mouth in patients. Results The average level of dry mouth of patients at 3 months after radiotherapy was significantly lower than that of radiotherapy (P <0.05), and there was significant difference of PSV, EDV and RI before and after radiotherapy (P <0.05). Conclusion B ultrasound has certain reference value for the detection of parotid gland function damage by radiotherapy. However, the quantitative analysis of parotid gland function damage remains to be further studied.
