Although stapedotomy is effective for patients with clinical otosclerosis, the time of hearing stabilization has not yet been consistent.
To investigate the relationships between post-operative follow-up times, hearing outcomes, and threshold shift after stapedotomy.
Fifty-five patients with clinical otosclerosis that underwent stapedotomy were retrospectively studied. Pure tone audiometry tests were conducted within the first month (short-term) and within 1 year (mid-term) postoperatively. Data were analyzed for two rounds of audiometry tests at different postoperative follow-up times.
Air conduction (AC) and bone conduction (BC) were significantly correlated with preoperative hearing levels (<.01). AC, BC, and air bone gap (ABG) significantly improved at the short-term (<.001) and continued to improve at the mid-term (<.01). The success rate of surgery increased from 87% at short-term to 98% at mid-term. Less than 1/3 of cases encountered BC deterioration at short-term, whereas most improved at mid-term.
Hearing results showed a trend of improvement between short-term and mid-term follow-ups after stapedotomy. AC, ABG, and success rate displayed significant improvement several months postoperatively. BC deterioration occurred in less than 30% of patients at short-term. The recovery of BC at 4 kHz was later than that of low frequencies.
尽管镫骨切除术对临床耳硬化症患者有效，但听力稳定的时间尚未一致。
探讨镫骨切除术患者术后随访时间、听力结果和镫骨术后听力阈移之间的关系。
回顾性研究 55 例临床耳硬化症患者，均行镫骨切除术。术后 1 个月内（短期）和 1 年内（中期）进行纯音测听检查。对不同术后随访时间的两轮听力测试进行数据分析。
气导（AC）和骨导（BC）与术前听力水平显著相关（<0.01）。短期（<0.001）和中期（<0.01）时 AC、BC 和气骨导差（ABG）显著改善。手术成功率从短期的 87%增加到中期的 98%。不到 1/3 的病例在短期出现 BC 恶化，而大多数在中期得到改善。
镫骨术后短期和中期随访听力结果均呈改善趋势。术后几个月 AC、ABG 和成功率显著改善。短期 BC 恶化发生率低于 30%。4 kHz 时 BC 的恢复晚于低频。
