摘要： 目的 建立激光中耳骨消融的活体动物模型,初步研究脉冲CO2激光及Er:YAG激光中耳骨消融的可行性,在耳科手术中寻求除电钻外另一快速、安全的手术工具方式。 方法 24只兔分为三组,分别采用电钻、CO2激光、Er:YAG激光为手术工具,研磨或消融中耳骨至暴露中耳腔,比较三种工具活体动物中实际操作的可行性,观察实验现象,比较手术速度,并利用连续组织切片HE染色技术检测周围组织形态改变。 结果 在活体兔实验模型中,两种激光系统及传统电钻都可达到有效开窗,三组手术工具开窗所用时间长短不一;三组暴露中耳腔所用时间差异无统计学意义(P>0.05);电钻磨骨与激光消融骨组织形态改变相似。 结论 使用激光可迅速消融骨质暴露中耳腔,激光可作为除电钻外的另一耳科手术工具。

Abstract: Objective To study the feasibility of bone ablation in middle ear with pulsed CO2 laser and Er:YAG laser in rabbit models, in order to provide a new and safe tool for fenestration operation in middle ear. Methods A total of 24 New Zealand rabbits were randomly divided into 3 groups: drill group, CO2 laser group, and Er:YAG laser group. The three tools were used to perform fenestration operation of middle ear. The feasibility of bone ablation, experimental phenomena, total operation time and light irradiation time, and opening efficiency were compared. The morphologic changes of adjacent tissues were observed with tissue slicing and HE staining after irradiation. Results All of the three approaches were suitable for fenestration operation of middle ear bone, with different operation time, but there was no statistical difference(P>0.05). The three groups had similar morphologic characteristics after fenestration. Conclusion Both pulsed CO2 laser and Er:YAG laser can ablate bone rapidly in the fenestration operation, which can serve as a new tool in otological surgeries besides electric drill.
