目的：回顾性分析比较鼓室硬化症与中耳胆脂瘤手术治疗前后听力变化情况。方法对36例中耳胆脂瘤患者，31例鼓室硬化患者手术前后听力变化进行回顾性总结，听力情况以500,1000,2000,4000Hz的气骨导差值分别进行统计分析比较。结果两组患者血钙水平没有明显差异；术前听力下降鼓室硬化症组比中耳胆脂瘤组严重；术后听力两组均较术前有显著提高，且两组之间听力改善没有显著差别。中耳胆脂瘤组和鼓室硬化症组的术后气骨导差在500,1000Hz频率均明显低于术前。同时手术对于中耳胆脂瘤组听力改善在2000和4000Hz明显优于鼓室硬化症组。结论手术对于鼓室硬化症的听力改善效果与中耳胆脂瘤相似，尤其对于中低频听力的提高效果明确。%Objective To study hearing outcomes following surgical treatment in tympanosclerosis and middle ear cho-lesteatoma. Methods Included in the study were 36 cases of middle ear cholesteatoma and 31 cases of tympanosclerosis. The air-bone gaps (ABG) at 500, 1000, 2000 and 4000 Hz before and after operation were compared. Results The serum cal-cium level was not significantly different between the two diagnoses groups. Preoperative hearing loss in tympanosclerosis was worse than in middle ear cholesteatoma. Postoperative hearing outcomes showed significant improvement in both diag-noses groups with no statistically significant difference between the two groups. Both groups showed significant reduction of air-bone gaps at 500 Hz and 1000 Hz after operation, but not at 4000 Hz. Postoperative hearing in patients with middle ear cholesteatoma was significantly better than in patients with tympanosclerosis at 2000 and 4000 Hz. Conclusions Hear-ing outcomes following surgical treatment are similar in tympanosclerosis and middle ear cholesteatoma. Postoperative hear-ing outcomes are especially better at mid and low frequencies.
