The treatment of otosclerosis is eminently surgical. Good immediate results have been well documented when stapedotomy or stapedectomy are chosen.
This study aims to assess long term audiometric performance after otosclerosis surgery.
this retrospective study enrolled stapedotomy and partial stapedectomy patients seen at our service with proven hearing improvement after surgery. Forty-one patients (47 ears) accepted the invitation to be reassessed. Audiometry results before and immediately after surgery were compared.
the median late follow-up was 11 years. To this date, 49% of the patients had normal hearing or mild dysacusis. Preoperative, postoperative, and late postoperative bone and air pure tone averages were 64.4 and 27.0 dB, 35.6 and 22.3 dB, and 44.1 and 29.5 dB respectively.
Otosclerosis surgery offers good long term results. Despite the worsening of thresholds, the level of hypacusis ten years after surgery is lower than the levels observed before surgery.
目的：本研究旨在评估耳硬化症手术后的长期听力表现。
材料与方法：本回顾性研究纳入了在我院接受过镫骨手术且术后听力改善得到证实的镫骨切开术和部分镫骨切除术患者。41 名患者（47 耳）接受了重新评估的邀请。比较了手术前后的听力结果。
结果：中位随访时间为 11 年。迄今为止，49%的患者听力正常或仅有轻度听力障碍。术前、术后和晚期术后骨气导纯音平均值分别为 64.4dB 和 27.0dB、35.6dB 和 22.3dB、44.1dB 和 29.5dB。
结论：耳硬化症手术可获得良好的长期效果。尽管阈值恶化，但术后 10 年的听力障碍程度低于术前观察到的水平。
