Abstract：
OBJECTIVE: To identify which patients with advanced otosclerosis may have the greatest audiologic improvement with stapedotomy based on different classifications of advanced otosclerosis.
METHODS: Retrospective chart review.
METHODS: Single tertiary neurotology center.
METHODS: Patients were divided into different classifications of advanced otosclerosis based on either a bone conduction threshold of greater than 60 dB HL (Bone Conduction (BC) Group), a word recognition score of less than 70% (Word Recognition (WRS) Group), or pure tone average of greater than 85 dB HL (Pure Tone Average (PTA) Group). Audiologic outcomes and complication profiles were compared between these groups.
RESULTS: Nineteen patients met criteria for one or more group. There were 18 patients in the PTA group, 11 in the BC group, and 12 in the WRS group. There was no significant difference in the pre- or postoperative audiologic status between the different groups.
CONCLUSIONS: Patients with advanced otosclerosis have significant improvements in pure tone averages and air-bone gaps following stapedotomy regardless of the classification criteria used. Stapedotomy remains a reasonable primary intervention for the majority of patients with advanced otosclerosis.

摘要：
目的：根据晚期耳硬化症的不同分类，确定哪些晚期耳硬化症患者可能在stapedsurgery切开术中具有最大的听力学改善。
方法：回顾性图表回顾。
方法：单一三级神经中心。
方法：根据骨传导阈值大于60dBHL（骨传导（BC）组）将患者分为不同的晚期耳硬化症分类。单词识别得分低于70%(单词识别(WRS)组)，或纯音平均大于85dBHL（纯音平均（PTA）组）。比较了这些组之间的听力学结果和并发症情况。
结果：19名患者符合一个或多个组的标准。PTA组18例,11在BC组中，WRS组12人。不同组之间的术前或术后听力学状况没有显着差异。
结论：无论使用何种分类标准，晚期耳硬化症患者在stapedci切开术后的纯音平均值和空气-骨间隙均有显著改善。对于大多数晚期耳硬化症患者，stapedsometry切开术仍然是合理的主要干预措施。
