对100例突聋病人施行耳蜗电图描记,发现有以下几种情况:①AP反应良好;②AP振幅减小;③宽AP波形.这种波形中包含有AP波形和—增大的—SP波形,—SP振幅和AP振幅几相等,我们称之为优势—SP;④AP无反应;⑤只有—SP或+SP;⑤AP,SP无反应。 将100例突聋病人分为三组:①预后满意组23例,其中10例AP反应正常,12例表现优势—SP。此组病 A total of 100 cases of sudden deafness patients underwent electrochromogram, found the following situations: ① AP response is good; ② AP amplitude decreases; ③ wide AP waveform. This waveform contains the AP waveform and - increased-SP waveform, -SP amplitude and AP amplitude of several equal, we call the advantage-SP; ④ AP no reaction; ⑤ only-SP or + SP; ⑤ AP, SP no response. One hundred patients with sudden deafness were divided into three groups: ① In 23 patients with satisfactory prognosis, AP was normal in 10 patients and superior in 12. This group of diseases
