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 (5 0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 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 (2 7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。 Objective: To understand the types and effects of eustachian tube dysfunction after radiotherapy of nasopharyngeal carcinoma. Methods: Thirty-two patients (50 ears) with eustachian tube dysfunction after radiotherapy were routinely examined, audiometer, tympanogram, TTAG examination, Eustachian tube sound examination and endoscopy Eustachian tube pharynx mouth. Results: Eustachian tube was abnormally open in 2 cases (4 ears) with mild symptoms. Eustachian tube adhesions in 5 cases (7 ears), eustachian tube obstruction in 17 cases (27 ears), eustachian tube obstruction in 8 cases (12 ears), after the three symptoms similar to the main cause of secretory otitis media. Conclusion: After radiotherapy, nasopharyngeal carcinoma can cause different types of eustachian tube dysfunction and damage to ear function, and understanding of it will be helpful for the determination of targeted treatment.
