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.
