对因耳硬化症而施行镫骨切除手术的315例(384耳)患者术后纯音听力进行了回顾性研究,旨在观察年龄因素对手术效果的影响。基本术式为镫骨全切除,软骨衣封闭卵圆窗并植入耳屏软骨。患者按年龄分五组,其中51～60岁组例数最多,平均年龄47岁。比较各组间术前、术后0.5、1、2、4kHz纯音气骨导听阈及其间距值(ABG)。术前ABG值随年龄增长而加大,预示60岁以上组术后听力改善应较
A retrospective study was conducted on postoperative pure tone hearing in 315 patients (384 ears) with otorrectomy due to otosclerosis in order to observe the effect of age on the surgical outcome. The basic operation for the total tarsal resection, cartilage closed oval window and implanted tragus cartilage. Patients were divided into five groups by age, of which 51 to 60 years old the largest number of cases, with an average age of 47 years. The preoperative and postoperative 0.5, 1, 2, 4 kHz pure tone air-to-air conduction were measured and their ABG values were compared. Preoperative ABG values increased with age, indicating improvement in hearing after surgery in patients over 60 should be compared
