摘要
目的 :观察鼻咽癌放疗对前庭功能的影响。方法 :对 2 0例鼻咽癌患者行常规根治放疗 ,剂量为 70 Gy,3例放疗量 >70 Gy。结果 :9例 (45 % )出现前庭功能异常 ,其中 3例记录到自发性眼震 ;患侧前庭功能减弱 4例 ;双侧前庭功能减弱和双侧前庭功能丧失各 2例。另 11例 (5 5 % )前庭功能正常。结论 :鼻咽癌放疗后可损害前庭功能 ,在进行职业鉴定时要考虑此因素 ,并应对前庭功能、听功能和咽鼓管功能分别予以评价。
Objective:To investigate effects on vestibular function by irradiation in the patients with nasopharyngeal carcinoma.Method:Twenty patients with nasopharyngeal carcinoma were routinely irradiated with dose of 70 Gy (3 cases>70 Gy).Result:Nine cases (45%) were abnormal in vestibular function test after radical irradiation in 20 cases(spontaneous nystagmus n=3;unlateral canal paresis n=4;bilateral canal paresis n=2;bilateral vestibular function absent n=2).The other 11 cases(55%) were normal in vestibular function test.Conclusion:Vestibular function may be damaged after radical irradiation in patients with nasopharyngeal carcinoma.During professional identification, this factor must be respected and vestibular function,cochlear function and tubal function must be separately evaluated.
