The authors have studied the use of the CO(2) laser in performing primary stapedotomy in 451 patients affected by otosclerosis, operated between 1996 and 2000. Footplate perforation was practised with a traditional method, by means of a microdrill, in 169 subjects. A CO(2) laser was instead used in other 282 cases; the authors effected the platinotomy with a single spot, repeated if necessary, with the diameter adjusted to the caliber of the prosthesis. This procedure allowed a smooth-edged perforation to be obtained. In the 282 laser-operated patients, there was a significantly higher proportion having closure of the cochlear reserve within 10 dB than that found in the cases where the microdrill was used. Moreover, no postoperative anacusia or severe vertigo were recorded; this confirms the safety of the CO(2) laser as regards the inner ear. The functional results, therefore, document the validity of the exposed technique.
作者研究了1996年至2000年间对451例耳硬化症患者进行初次镫骨切除术时二氧化碳激光的使用情况。169名受试者采用传统方法，通过微型钻头进行足板穿孔。另外282例则使用了二氧化碳激光；作者用单点进行镫骨切开术，必要时重复，直径根据假体口径调整。该操作可获得边缘光滑的穿孔。在282例接受激光手术的患者中，耳蜗储备在10 dB内闭合的比例明显高于使用微型钻头的病例。此外，未记录到术后全聋或严重眩晕；这证实了二氧化碳激光对内耳的安全性。因此，功能结果证明了所采用技术的有效性。
