The authors studied variations of the position of stapes in the fossula of ovale window on 300 preparations of temporal bones, under operating microscope. They noted three possible positions of the stapes: most commonly downwards to the promontorium (76%), much less frequently (15%) towards the bottom of the fossula, and rarely upwards to the facial canal (9%). Knowledge of these anatomic variations is of great importance in surgical procedures performed in this region.
作者在手术显微镜下，对300例颞骨标本的卵圆窗小窝内镫骨位置的变异进行了研究。他们注意到镫骨有三种可能的位置：最常见的是向下朝向鼓岬（76%），较少见的是朝向小窝底部（15%），很少向上朝向面神经管（9%）。了解这些解剖变异在该区域进行的外科手术中非常重要。
