激光照射于耳蜗,引起的变化是相当局限的,当激光作用于猴迷路的前庭部分,前庭功能明显破坏时听觉尚可保存。作者以前的研究曾证实当激光作用于猴的外半规管时,形态学的变化仅限于被照射的半规管壶腹部。在迷路外科,特别是在美尼尔氏病,应用激光可在所希望的部位引起局限性的破坏。本文用16只体重2～2.5kg的家兔作试验,用钕激光250焦耳/cm~2照射垂直半规管,以消除前庭功能,对侧迷路作为对照。在激光照射后1小时、3昼夜和1个月后剖检动物。制做标本时在显微镜下目视评价膜性迷路情况。在1小时后
Laser irradiation of the cochlear, caused by the change is quite limited, when the laser effect on the monkey vestibular part of the vestibular function was significantly damaged hearing can be preserved. Previous studies by the authors have demonstrated that when the laser acts on the monkey’s semicircular canal, the morphological changes are limited to the irradiated semicircular canal ampulla. In labyrinth surgery, particularly in Meniere’s disease, applying a laser can cause localized damage at the desired site. In this paper, 16 rabbits weighing 2 ~ 2.5kg were used as the experiment. The vertical semicircular canal was irradiated with 250Joules / cm ~ 2 neodymium laser to eliminate the vestibular function and contralateral labyrinth as control. Animals were necropsied 1 hour, 3 days and 1 month after laser irradiation. Preparation of specimens under the microscope visual evaluation of the situation of membranous labyrinth. After 1 hour
