【摘要】：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。
[Abstract]:Objective to analyze and compare the hearing changes of tympanic sclerosis and middle ear cholesteatoma before and after operation. Methods the hearing changes of 36 patients with middle ear cholesteatoma and 31 patients with tympanic sclerosis before and after operation were retrospectively summarized. Results there was no significant difference in serum calcium level between the two groups, the hearing loss in tympanic sclerosis group was more serious than that in middle ear cholesteatoma group, and the postoperative hearing level in both groups was significantly higher than that before operation, and there was no significant difference in hearing improvement between the two groups. In the middle ear cholesteatoma group and tympanic sclerosis group, the frequency of air-bone conductance difference at 500 ~ 1000 Hz was significantly lower than that before operation. At the same time, the hearing improvement of middle ear cholesteatoma group was significantly better than that of tympanic sclerosis group in 2000 and 4000Hz. Conclusion the effect of operation on hearing improvement in tympanic sclerosis is similar to that in middle ear cholesteatoma, especially in middle and low frequency hearing.
