中耳炎积液是否会引起骨导改变,仍有争论。作者对453例中耳炎鼓室积液患儿进行观察。患儿均做鼓膜切开或插管治疗。术前术后进行鼓气耳镜、纯音测听、阻抗测听检查,随诊一年。检查结果发现有27例骨导损失在25dB以上。经过治疗有22例(81％)骨导阈改善10dB 以上,其2KHz 改善11.9dB,4KHz 改善24.4dB,500Hz 改善为14.4dB,250Hz 改善为21.2dB。证实中耳炎鼓室积液可引起骨导听力损
Whether otitis media effusion can cause bone conduction changes remains controversial. The authors observed 453 cases of otitis media tympanic effusion in children. Children are done tympanotomy or intubation treatment. Preoperative and postoperative otoscopy, pure tone audiometry, impedance audiometry, followed up for one year. Inspection results found that 27 cases of bone conduction loss in more than 25dB. After treatment, 22 cases (81%) improved the bone conduction threshold by more than 10dB, the improvement of 11.8dB at 2KHz, 24.4dB at 4KHz, 14.4dB at 500Hz and 21.2dB at 250Hz. Confirmed otitis media tympanic fluid can cause bone conduction hearing loss
