核磁共振成像在突发性聋诊治中的应用

Application of MRI in diagnosing sudden deafness

目的：探讨核磁共振成像（MRI）在诊治突发性聋的价值。方法：回顾分析2000～2005年21例、21耳计算机X线断层摄影术检查无异常、经系统综合治疗1周后无好转，再行MRI检查的交发性聋患者的临床特点、听力学及治疗经过，并复习相关文献。结果：21例患者中，5例经MRI检查发现有病理性改变。结论：对于经系统治疗1周左右、效果欠佳的突发性聋患者，建议加做MRI。

Objective： To explore the application of MRI in diagnosing sudden deafness. Methods： No pathological symptoms were found on 21 patients with sudden deafness by computerized tomography and they accepted systematical treatment for one week but did not get any improvement. Then they were examined by magnetic resonance imaging. Their medical data, including hearing level and treatment course were retrospectively analyzed. In addition, the related literatures were reviewed. Result： Out of the 21 patients, 5 showed pathological changes by magnetic resonance imaging. Conclusion： To those sudden deafness patients whose symptoms do not alleviate after systematical treatment of one week, magnetic resonance imaging should be applied to discover some covered pathological changes.
