To evaluate the effect of ossicular reconstruction with partial ossicular replacement prosthesis (PORP) in patients with tympanosclerosis.
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.
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).
In ossicular attic fixation, ossicular reconstruction using PORP can yield better results than mobilization of the major ossicles in patients with tympanosclerosis.
评估部分听骨赝复物（PORP）行听骨链重建术治疗鼓室硬化症患者的疗效。
回顾性分析1992年至2006年期间治疗的28例鼓室硬化症患者的资料。28例患者中，14例（14耳）采用PORP行听骨链重建术，14例（14耳）行听骨链松动术，所有患者均随访3至24个月。
两组患者术后言语频率（500、1000、2000Hz）纯音平均听阈（PTA）及气骨导间距（ABG）缩小均有显著改善。采用PORP行听骨链重建术的患者ABG缩小及PTA改善在统计学上更显著（P<0.05）。
对于鼓室硬化症患者听骨上鼓室固定的情况，采用PORP行听骨链重建术比主要听骨松动术效果更好。
