目的通过对比术前纯音测听结果与术中所见听骨链的情况，探讨鼓室硬化症患者纯音听阈特征。方法回顾分析2008年～2011年31例鼓室硬化住院手术病例，分析患者气、骨导听力，气骨导差（ABG），中耳病变情况。结果31例中，混合性听力损失20例，传导性HL10例，感音神经性HL1例；手术探查钙斑散在分布，听骨链有不同程度的固定，听骨链完整20例，破坏11例。结论鼓室硬化病人听力损失主要为混合性及传导性，平行曲线者鼓室硬多较重，横V曲线鼓室硬化多较轻，ABG>30dBHL提示听骨链固定或破坏，但ABG<30dBHL不能轻易否定听骨链固定或破坏。

Objective By comparing the preoperative pure tone audiometry and intraoperative auditory ossicle chain, seen on patients with middle ear sclerosis pure tone hearing threshold characteristic. Methods Retrospective analysis of 2008~ 2011, 31 cases of tympanic cavity hardening hospital surgery cases, analysis of patients with air and bone conduction hearing, bones guide (ABG), middle ear disease. Results 31 patients, 20 patients with mixed hearing loss, and conductivity HL10 example, sensorineural HL1 cases; Ploration calcium spots scattered distribution, auditory ossicle chain have different degree of fixed, auditory ossicle chain of 20 patients with complete destruction in 11 cases. Conclusion Middle ear sclerosis patients mainly combination, and conductive hearing losses, parallel curve of drum-type hard much heavier, cross V curve drum-type hardening much lighter, ABG > 30 DBHL prompt auditory ossicle chain fixed or damage, but the ABG < 30 DBHL cannot easily deny auditory ossicle chain fixed or destruction.
