漂浮导管扩张咽鼓管治疗放疗后分泌性中耳炎

目的：了解鼻咽癌(NPC)放疗后分泌性中耳炎(SOM)咽鼓管功能，以及漂浮导管扩张咽鼓管治疗该病的临床价值。方法：使用咽鼓管功能综合检查仪检测21例(37耳)NPC放疗后SOM患者的咽鼓管功能；在鼻内镜直视下将漂浮导管导入咽鼓管内扩张咽鼓管，治疗NPC放疗后咽鼓管阻塞引起的SOM。结果：21例NPC放疗后SOM中，咽鼓管功能为正常型2耳，阻塞型21耳，闭锁不全型8耳，开放型6耳。漂浮导管扩张咽鼓管治疗NPC放疗后SOM，有效率为43．2％(16／37)。结论：NPC放疗后SOM的咽鼓管功能障碍，多以阻塞型为主，应用漂浮导管扩张咽鼓管是一种有效的治疗方法。

Application of floating tube in dilation of eustachian tube under nasal endoscopy to treat post-irradiation secretory otitis media

Objective:To analyse the function of eustachian tube in post-irradiation secretory otitis media and investigate the curative effect of dilating eustachian tube with Swan-Gans thermodilution catheter for treating post-irradiation secretory otitis media in NPC patients.Method:Twenty-one(37 ears) post-irradiation secretory otitis media patients with NPC were selected in this study,by using eustachian tube function synthetic inspection facility(JK-04A model), the eustachian tube function was examined, and the obstructive eustachian tube was dilated with Swan-Gans thermodilution catheter under nasal endoscopy.Result:The eustachian tube function in 37 ears with post-irradiation secretory otitis media reveals normal, obstructive, insufficiency and opening model was 2,21,8, and 6 respectively. The total curative effect of dilating eustachian tube with Swan-Gans thermodilution catheter to treat post-irradiation secretory otitis was 43.2%(16/37).Conclusion:The eustachian tube function in post-irradiation secretory otitis media mainly reveals obstructive disturbance.The application of Swan-Gans thermodilution catheter in dilation of obstructive eustachian tube under nasal endoscopy will increase the curability of post-irradiation secretory otitis media.
