近年来由 Shambough,G.E.提倡早期耳硬化症可以用氟化钠(NaFl)进行治疗,诊断早期耳硬化症便显得重要了。作者用电声阻抗仪对病程在5年以内的13名各种年龄的患者进行了研究。早期耳硬化症的患者往往只有耳鸣和耳闷胀感,而听力下降不很明显。在电声阻抗仪测镫骨肌反射时,可出现一种双负相反射。它是在发放声音刺激后出现第一个负相小波,随即平伏,当刺激声停止后,又出现一个类似的小波。故上述现象
In recent years, Shambough and G.E. advocate that early otosclerosis can be treated with sodium fluoride (NaFl), and it is important to diagnose early otosclerosis. The authors studied the 13 patients of various ages within 5 years with an electroacoustic impedance spectrometer. Patients with early otosclerosis are often tinnitus and stuffy ears, while hearing loss is not obvious. In the electro-acoustic impedance meter measured psoralen muscle reflex, there may be a double negative phase reflex. It is the first negative-phase wave that appears after the sound stimulus is released, and then falls flat. A similar wavelet appears again when the stimulus is stopped. So the above phenomenon
