摘要
目的探讨胆脂瘤型中耳炎的听力特点,为临床干预胆脂瘤型中耳炎提供依据。方法回顾性分析156耳胆脂瘤型中耳炎患者术前纯音听阈临床资料,结合听骨链破坏情况作统计学分析。结果病例中男性84耳,女性72耳,平均年龄32.98岁(6～78岁),听力损害在不同性别、年龄、民族、病程中差异无显著性(P>0.05);不同频率之间的骨导听阈差异有统计学意义(P<0.01);听骨链破坏在不同性别、年龄、民族中差异无显著性(P>0.05),听骨链破坏程度在不同病程中差异有显著性(P<0.01)。结论在胆脂瘤型中耳炎病例中,不同频率间的骨导听力损失不同,以高频听力损失为主;病程越长,听骨链破坏越严重。
Objective To study features of hearing loss in human middle ear cholesteatoma for the purpose of preventing the development of cholesteatoma. Methods Audiometric data in 156 cases （156 ears） of middle ear cholesteatoma were reviewed and compared to the degree of ossicular destruction. Results Of the 156 patients, 84 were males and 72 were females, aging 6 to 78 years （average 32.98 years）. Hearing loss was not correlated to sex, age, ethnicity or disease duration （P 0.05）. Bone conduction thresholds were different at different frequencies （P 0.01）. Ossicular destruction was not correlated to sex, age or ethnicity, but to disease duration （P 0.01）. Conclusion Bone conduction hearing thresholds indicate mainly hearing damage in the 2 ~ 4 kHz range in middle ear cholesteatoma. Ossicular destruction increases as the duration of ear disease prolongs.
