对55例眩晕患者以耳蜗电图配合甘油试验观察耳蜗电图的变化,结果33例梅尼埃病(MD)患者甘油试验前耳蜗电图优势SP AP占73%;甘油试验阳性率为52%;服甘油后优势SPAP比值降至正常或减少15%以上.从而进一步证实优势SP是内淋巴积水的表现;以耳蜗电图配合甘油试验较纯音测听的甘油试验诊断MD更为客观. Fifty-five patients with vertigo were observed by electrochromogram and glycerin test. The results showed that the electrocardiogram (EP) of 33 patients with Ménière’s disease (MD) before surgery was 73%, and the positive rate of glycerol test was 52% ; After taking glycerol, the advantage SPAP ratio dropped to normal or decreased more than 15%, thus further confirming that the superiority SP is the manifestation of endolymphatic hydrops, and the electrocochilogram with glycerol test is more objective than the pure tone audiometry glycerin test.
