We illustrate that the apparent sensorineural audiometric changes immediately following stapedectomy are not indicative of a true sensorineural type hearing loss. The cochlear changes evident by postoperative pure-tone and air conduction speech discrimination audiometric tests are not reflective of the true cochlear reserve when the procedure of bone conduction speech discrimination is used. We report 25 consecutive stapedectomy cases in which most of the one-week postoperative audiograms of stapedectomized ears revealed a mid- and high-frequency sensorineural pure-tone loss and a drop in the standard speech discrimination scores. The decrease in speech discrimination, however, was not verified when using the bone-speech discrimination test, using maximum masking in the opposite ear.
我们证明，镫骨切除术后立即出现的明显感音神经性听力测量变化并不表明存在真正的感音神经性听力损失。当使用骨导言语辨别程序时，术后纯音和气导言语辨别听力测试中明显的耳蜗变化并不能反映真正的耳蜗储备。我们报告了连续25例镫骨切除术病例，其中大多数接受镫骨切除术耳朵术后一周的听力图显示中高频感音神经性纯音损失以及标准言语辨别分数下降。然而，当使用对侧耳最大掩蔽的骨导言语辨别测试时，言语辨别能力的下降并未得到证实。
