采用随机、双盲法对特发性突聋病例进行了微波辐射与单纯药物治疗效果的比较，从而对微波的疗效作出重新的评价。结果表明微波治疗组的有效率为８１８１％，听力达实用水平者为５４５４％；而药物治疗组的有效率为２７２７％，两组间有极显著差异（Ｐ＜０００１）。对发病后２周以上、２个月以内的患者，药物组中无１例听力有任何程度的恢复；而在微波组的６例中，有３例听力有不同程度的恢复，其中有２例竟恢复到实用水平以内。资料还表明年龄的大小对治疗的效果影响不明显，在５０～７５岁与７～４９岁两年龄亚组的比较中，其间并无显著差异（Ｐ＜００５）。然而，在微波与药物治疗两组间相比，其间差异显著（Ｐ＜００１）。结果表明微波对特发性聋的疗效较药物治疗优越。作者在以前实验结果的基础上认为微波治聋的特点在于其能量集中，能穿透组织达一定深度。因此，对耳辐射时能在内耳发生直接的生物效应，其作用机制是改善内耳微循环的血流，提高血管纹红细胞的充盈 A randomized, double-blind method for idiopathic sudden deafness cases of microwave radiation and the effect of simple drug treatment compared to the efficacy of microwave re-evaluation. The results showed that the effective rate of microwave treatment group was 8181% and the hearing level reached 5454%; while the effective rate of drug treatment group was 2727%, with significant difference between the two groups (P <0 001). For patients who were more than 2 weeks after onset and within 2 months, none of the patients in the drug group had any degree of hearing recovery, while in the 6 cases of the microwave group, 3 patients had different degree of hearing recovery, of which 2 patients Actually restored to the practical level. The data also showed that the effect of age on the effect of treatment is not obvious. There was no significant difference between the two age groups of 50-75 years and 7-49 years (P <005). However, there was a significant difference between the microwave and drug treatment groups (P <001). The results show that microwave treatment of idiopathic deafness superior to the drug treatment. Based on the previous experimental results, the author thinks that the characteristic of microwave deafness is that its energy is concentrated and can penetrate tissues to a certain depth. Therefore, the ear radiation can occur in the inner ear direct biological effects, its mechanism of action is to improve blood flow in the inner ear microcirculation and improve the filling of vascular red blood cells
