The purpose of this study was to compare the hearing results of performing stapedotomy using either a microdrill or a perforator. Two groups of patients, otherwise similar, were followed up for at least 2 years after the stapedotomy. It was possible to create 0.8 mm fenestra in 91.6% of our patients. There was no significant difference between the two groups in hearing results. The results showed a continuous improvement in the first 6 post-operative months after which the hearing stabilized. In our hands, the microdrill has not proved to be more traumatic than the perforator to the inner ear.
本研究的目的是比较使用微型钻头或穿孔器进行镫骨手术的听力结果。两组情况相似的患者在镫骨手术后至少随访了2年。我们91.6%的患者能够制造出0.8毫米的开窗。两组的听力结果没有显著差异。结果显示，术后前6个月听力持续改善，之后听力稳定。在我们的操作中，微型钻头对内耳造成的创伤并不比穿孔器更大。
