特发性突聋是一种不明原因的耳蜗性听力减退。病毒感染可能是一种原因,内耳血循环的紊乱可能是另一原因。作者应用降低纤维蛋白原药物(DF),减低血浆中纤维蛋白原水平以降低血液粘滞度。用 DF 和类固醇两种治疗方法,在169个病人中,用两组双盲对照法试验。选择病人的标准是:1.纯音听力曲线的五个频率(250～4000Hz)的平均听力水平应低于55dB;2.发生 Idiopathic sudden deafness is an unknown cause of cochlear hearing loss. Viral infection may be a reason, the disorder of the inner ear blood circulation may be another reason. The authors applied a method of reducing fibrinogen (DF) and lowering plasma fibrinogen levels to reduce blood viscosity. Two treatment regimens, DF and steroids, were used in 169 patients with two double-blind controls. The criteria for selecting a patient are: 1. The average hearing level of the five frequencies (250-4000 Hz) of the pure tone audiogram should be less than 55 dB; 2. Occurs
