We evaluated the variation in bone conduction auditory thresholds in patients undergoing surgical intervention for otosclerosis as part of our report on the use of surgery in patients with a small air-bone gap. Of the 110 patients who underwent stapedotomy, 45 were treated by traditional surgery and 65 with carbon dioxide laser, with a follow-up of 3 years at 500-, 1000-, 2000-, and 3000-Hz frequencies. Both surgical techniques resulted in improvements in air conduction in more than 95% of cases; bone conduction improved more in patients treated with carbon dioxide laser (7.1 dB) compared to those treated with traditional surgery (4 dB) (P < .01). Furthermore, improvement in bone conduction was greater and more frequent in younger subjects (below 45 years) (P < .05). In conclusion, this study allows us to express a positive prognosis when considering otosclerotic patients with sensorineural hearing loss and small air-bone gap.
作为我们关于气骨导间距小的患者手术应用报告的一部分，我们评估了耳硬化症手术患者骨导听阈的变化。在110例行镫骨切除术的患者中，45例接受传统手术治疗，65例接受二氧化碳激光治疗，在500、1000、2000和3000赫兹频率下随访3年。两种手术技术在超过95%的病例中均使气导得到改善；与接受传统手术的患者（4分贝）相比，接受二氧化碳激光治疗的患者骨导改善更明显（7.1分贝）（P < 0.01）。此外，年轻受试者（45岁以下）骨导改善更大且更频繁（P < 0.05）。总之，本研究使我们在考虑患有感音神经性听力损失和气骨导间距小的耳硬化症患者时能够给出积极的预后判断。
