摘要
对１８只白色豚鼠施行单侧外半规管外淋巴间隙阻断术。术前、后观察ＡＢＲ、旋转试验，并作火棉胶连续切片光镜检查。结果提示：手术前、后ＡＢＲ阈值经统计学处理差异无显著性，而限震持续时间差异有显著性（术后缩短），初步表明本手术可致豚鼠前庭功能降低而未明显损伤耳蜗功能。
Obliteration of the external lymphatic space on 18 guinea pigs was performed.The lymphatic space of the horizontal semicircular canal was blocked by fascia, Auditory(ABR) and vestibular functions were tested before and after the surgical obliteration。Morphologic changes in the cochlea and vestibule were observed under light microscope. It was found that there was no significant difference in the threshold of ABR before and after the operation However,the sustained time of nystagmus was significantly decreased after the operation,Our results indicate that this surgical proce-dure may damage vestibular function,but produce no evident damage to the cochlear function.
