OBJECTIVE
Erbium (Er.) YAG laser may be usable for middle ear surgery because of its ability to ablate bony tissue. We investigated the inner ear damage caused by the fenestration to the inner ear with Er. YAG laser.
DESIGN
We investigated the influence of Er. YAG laser on the inner ear using electrophysiological technique.
RESULTS
Several cases had a decrease in endocochlear potential (EP) and cochlear microphonics (CM) after the fenestration to the inner ear.
CONCLUSIONS
Er. YAG laser is safe if it is used for the small and superficial fenestration to the stapes footplate. However, a few extra pulses after fenestration are dangerous.
目的
铒（Er.）钇铝石榴石激光因其能够消融骨组织，可能可用于中耳手术。我们研究了用Er. YAG激光对内耳开窗造成的内耳损伤。
设计
我们使用电生理技术研究了Er. YAG激光对内耳的影响。
结果
几例在内耳开窗后出现了内耳蜗电位（EP）和耳蜗微音电位（CM）下降。
结论
如果将Er. YAG激光用于镫骨足板的小而浅的开窗，是安全的。然而，开窗后额外的几次脉冲是危险的。
