摘要： 目的探讨生物陶瓷人工听骨在鼓室硬化手术中应用的疗效。方法回顾性分析1992年至2006年鼓室硬化锤砧固定型资料完整病例28例(28耳),术中运用生物陶瓷人工听骨14例(14耳),去除硬化灶后撼动听骨链14例(14 耳),术后随访3～24月,分析患者言语频率(500,1000,2000 Hz)纯音平均听阈(PTA)及气骨导差(ABG),比较两种术式的优劣。结果两组术后言语频率PTA及ABG较术前均缩小且有统计学意义,应用生物陶瓷人工听骨组明显优于撼动听骨链组(P<0．05)。结论术中应用生物陶瓷人工听骨在提高鼓室硬化病人的听力方面具有较好的疗效。

Abstract: Objective To evaluate the effect of ossicular reconstruction with partial ossicular replacement prosthesis (PORP) in patients with tympanosclerosis. Methods The data of 28 cases of tympanosclerosis treated between 1992 and 2006 were reviewed. Of the 28 patients, 14 (14 ears) underwent ossicular reconstruction with PORP and 14 (14 ears) had ossicular mobilization, and all the patients were followed-up for 3-24 months. Results Significant improvement was found in postoperative speech frequency (500, 1000, 2000 Hz) pure tone average (PTA) and air-bone gap (ABG) closure after in the operation the two groups. Ossicular reconstruction using PORP resulted in statistically better ABG closure and PTA (P<0.05). Conclusion In ossicular attic fixation, ossicular reconstruction using PORP can yield better results than mobilization of the major ossicles in patients with tympanosclerosis.
