耳内窥镜在耳硬化症人工镫骨手术中的应用研究

摘要： 目的??探讨耳内窥镜在耳硬化症人工镫骨手术中的应用。方法?对64例耳硬化患者分别采用显微镜或耳内窥镜两种放大设备下行人工镫骨手术，对手术所需时间及术后手术效果进行分析和总结。结果?两组患者术后听力均明显改善，气骨导差均较术前降低，差异有统计学意义（P <0.05），患者术中术后均无任何并发症，耳内窥镜组手术所需时间比显微镜组稍长，但两组手术所需时间比较差异无统计学意义（P >0.05）。结论?耳内窥镜下行人工镫骨手术，探查听骨链，重建听力，图像清晰、创伤小，与显微镜下手术相比较具有自已独特的优势。
Abstract: Objective?To investigate the application of ear endoscopic in artificial stapes surgery of otosclerosis.?Methods?Artificial stapes surgery was performed by two amplification device, microscope or ear endoscope, in 64 cases of patients with otosclerosi. Then compare the operation time and analyze the effect of surgery.?Results?Patients postoperative hearing of the two groups were significantly improved, the difference of air bone conduction was statistically significant (P < 0.05). There has no postoperative complications of all the patients. While the operation time was slightly longer in ear endoscope group than that in microscope group, and the difference has statistical significance (P > 0.05).?Conclusion?Compared with microscopic surgery, ear endoscope artificial stapes surgery has its’ unique advantages with clear image and small trauma.
