ABSTRACT

OBJECTIVE@#To investigate the clinical features and therapeutic effects of sudden deafness after radiotherapy combined with chemotherapy in nasopharyngeal carcinoma patients.@*METHOD@#Clinical data of 42 nasopharyngeal carcinoma patients suffered from sudden deafness after radiotherapy combined with chemotherapy were analyzed retrospectively. Among the 42 patients, 2 showed moderate deafness, 4 presented excessive deafness, 30 suffered from severe deafness, and 6 exhibited profound deafness. The audiogram pattern of 33 patients met with the type of high tone frequencies hearing loss, and that of the rest 9 cases showed hearing loss at all frequencies. All patients received medical therapy combined with hyperbaric oxygen therapy.@*RESULT@#Of all the cases with hearing loss, 2 were cured, 2 showed excellent recovery, 9 came out partial recovery, and 29 showed no response to the treatment. The total effective rate was 30.95%. For the accompanied symptoms, none of the 30 cases of tinnitus were relieved, 3 out of 10 cases of aural fullness were cured, and the 5 cases of dizziness or vertigo were all improved.@*CONCLUSION@#The sudden deafness after radiotherapy combined with chemotherapy in patients with nasopharyngeal carcinoma is closely related to radiotherapy. The hearing loss is serious, and the therapeutic effects are not satisfactory.
