In guinea pigs the cochlea microphonics (CM) were recorded during and after argon laser stapedotomy. Short termed drastic depression of CM was observed. This effect involved the entire frequency range of the cochlea. The recovery was mostly complete and often started already during laser irradiation or at the end of the laser exposure. A marked sensitivity loss of the cochlea only occurred with large stapedotomy holes followed by massive perilymph leakage. A momentary heat related instability of the entire stapes is suggested to cause the CM depression. In addition we observed a thermoacoustic effect on the CM. This laser evoked response seems to cause no harm to the cochlea.
在豚鼠身上，在氩激光镫骨切除术期间及术后记录了耳蜗微音电位（CM）。观察到CM出现短期的急剧下降。这种效应涉及耳蜗的整个频率范围。恢复大多是完全的，并且常常在激光照射期间或激光暴露结束时就已经开始。仅在镫骨切除孔较大且伴有大量外淋巴漏出时，才会出现耳蜗明显的敏感性丧失。提示整个镫骨瞬间与热相关的不稳定性导致CM下降。此外，我们观察到对CM有热声效应。这种激光诱发的反应似乎对耳蜗没有损害。
