The virtual image of the incus formed by the saline lens is an aid to the safe dissection of the antrum. The saline irrigation fluid indeed may act as a thin negative lens which permits at the antrum the visualization of the image of the incus, around the corner of the bony canal wall overhang. This warning device, predicting the exposure of the incus, prevent in this way inadvertent contact of this ossicle by the power drill and subsequent acoustic trauma.
由生理盐水透镜形成的砧骨虚像有助于安全地进行鼓窦解剖。生理盐水冲洗液实际上可能起到薄凹透镜的作用，它能使鼓窦处看到砧骨的影像，该影像位于骨管壁悬垂的拐角周围。这种预测砧骨暴露的警示装置，以此防止动力钻意外接触该听小骨并避免随后的听觉损伤。
