鼻咽癌放疗后咽鼓管功能障碍的几种类型

目的：了解鼻咽癌放疗后咽鼓管功能障碍的类型及其影响。方法：对32例(50耳)鼻咽癌放疗后有咽鼓管功能障碍的患者进行常规检查、听力计检查、鼓室导抗图法检查、咽鼓管一鼓室气流动态法(TTAG)检查、咽鼓管音响法检查和内镜检查咽鼓管咽口。结果：咽鼓管异常开放2例(4耳)，患者症状较轻。咽鼓管粘连5例(7耳)，咽鼓管完全阻塞17例(27耳)，咽鼓管不全阻塞8例(12耳)，后三者症状相似，主要导致分泌性中耳炎。结论：鼻咽癌放疗后可导致不同类型的咽鼓管功能障碍，对耳功能产生损害，对其了解将有助于针对性治疗方法的确定。

The damaged types of eustachian tube function in the patients of nasopharyngeal carcinoma after radiotherapy

Objective:To study the types and the influences of eustachian tube function disorder in the patients of nasopharyngeal carcinoma(NPC) after radiotherapy.Method:Thirty two patients of NPC (50 ears) that the eustachian tube function were damaged after radiotherapy were examined by general examination, audiometer test, tympanometry, Tubo tymanoaerodynamic grapy (TTAG), sonotubometry and endoscope.Result:Two cases(4 ears) showed abnormal patency of eustachian tube, the patients' symptoms were lightly. The eustachian tube adhesion were found in five patients(7 ears), and 17 patients(27 ears) showed eustachian tube complete obstruction, eight patients (12 ears) showed eustachian tube uncompleted obstruction, they had the similitude symptoms.Conclusion:The damaged types of eustachian tube function in patients of NPC after radiotherapy are different, it will harm the ear function. Finding it out will help to choose the treating measures.
