研究鼻咽癌放射治疗与鼻窦炎的关系。方法 :对 12 7例鼻咽癌放疗前、后病人的鼻咽 CT进行观察 ,并对鼻窦炎的发病情况及其相关因素进行分析。结果 :放疗前鼻窦炎发病率为 49% ,放疗后鼻窦炎发病率为 86 % ,其中放疗前无鼻窦炎者放疗后 72 %患有鼻窦炎。放疗后 6个月至 1年是发生鼻窦炎的高峰期。结论 :鼻咽癌患者的鼻窦炎的发病率较高 ,其发病与肿瘤的 T分期、肿瘤的发生部位等因素有关。放疗可使鼻窦炎的发病率增加 ,放疗前后的鼻窦炎发病原因有所不同。
To study the relationship between nasopharyngeal carcinoma radiotherapy and sinusitis. Methods: Nasopharyngeal CT was observed in 127 cases of nasopharyngeal carcinoma before and after radiotherapy, and the incidence of sinusitis and its related factors were analyzed. Results: The incidence of sinusitis before radiotherapy was 49%. The incidence of sinusitis after radiotherapy was 86%. Among them, no sinusitis was found in 72% of patients with sinusitis before radiotherapy. 6 to 1 year after radiotherapy is the peak of sinusitis. Conclusion: The incidence of sinusitis in patients with nasopharyngeal carcinoma is high, the incidence of which is related to the T stage of the tumor and the site of the tumor. Radiation therapy can increase the incidence of sinusitis, sinusitis incidence of radiotherapy before and after the cause is different.
