Abstract: Objective： To investigate the longterm effect of radiotherapy on auditory brain stem function of patients with nasopharyngeal carcinoma(NPC). Methods： The auditory brain stem response(ABR) was examined in 33 patients (66 ears) with NPC before and at the first day, and on 3, 6, 12, 24 and 36 months after radiotherapy. Results： There were no obvious harmon auditory functions at the first day after radiotherapy. The auditory function decreased significantly at 6 months after radiotherapy and slightly recovered in the next 6 months, but after that it slightly decreased again. Conclusions： Conventional radiotherapy harms the auditory function in the longterm after treatment, so effective means should be adopted as early as possible.

[9] This study was aimed at determining vestibular involvement and the location and frequency of vestibular dysfunction in patients with auditory neuropathy. MethodsTwenty patients with non-syndromic auditory neuropathy were enrolled. Using vestibular test battery, we calculated the ocular vestibular-evoked myogenic potential(oVEMP), cervical vestibular-evoked myogenic potential(cVEMP), video head impulse test(vHIT), suppression head impulse paradigm(SHIMP), and caloric test results. ResultsThe oVEMP and cVEMP were calculated for all patients, and the abnormality rates were % and %, respectively, showing no significant difference. The vHIT in the lateral, anterior, and posterior semicircular canals, and SHIMP in the lateral canals were calculated for patients( ears), and the abnormality rates were %, %, %, and %, respectively, showing no significant difference among the four tests. Nineteen patients exhibited a % abnormality rate for the caloric test. Of the patients with the SHIMP and vHIT results, % showed abnormal caloric test results, which was much higher than the abnormality rate of SHIMP and vHIT. ConclusionPatients with auditory neuropathy showed vestibular involvement, and the superior and inferior vestibular components, including the vestibular peripheral receptors and nerves, had an equal probability of dysfunction. All the otolith organs and semicircular canals could be involved. The possibility of dysfunction was equal for different portions of the semicircular canal, while the functional involvement was more likely to be observed in low-frequency tests..
