【摘要】：目的探讨耳内镜下听骨链触动试验在慢性化脓性中耳炎术前评估中的应用。方法对38例(39耳)慢性化脓性中耳炎患者手术前予耳内镜检查、内镜下听骨链触动、纯音测听、鼓膜贴补试验、咽鼓管功能及颞骨CT等检查,根据检查结果选择不同的手术方式;将术前耳内镜下听骨链触动试验的结果、鼓膜贴补试验的结果及术中显微镜下探查听骨链的活动情况进行比较分析。结果耳内镜下听骨链触动试验对慢性化脓性中耳炎听骨链病变的诊断灵敏度、特异度、准确度分别是89.5%、80%、84.6%。鼓膜贴补试验的是50%、57.59%、54.5%。结论不同角度的耳内镜对中耳鼓室结构、听骨链活动情况进行观察,与手术中显微镜下所见有较高的符合率,术前使用耳内镜评估慢性化脓性中耳炎听骨链病变有重要的临床应用价值。
[Abstract]:Objective to evaluate the preoperative evaluation of chronic suppurative otitis media by auditory ossicular chain touch test. Methods 38 cases (39 ears) of chronic suppurative otitis media were examined by endoscopy before operation. Endoscopic ossicular chain touch, pure tone audiometry, tympanic membrane patch test, eustachian tube function and CT examination of temporal bone were selected according to the examination results. The results of preoperative otoscopic ossicular chain touch test were analyzed. Results the results of tympanic membrane patch test and the activity of ossicular chain under microscope were compared. Results the sensitivity of otoscope ossicular chain touch test in the diagnosis of chronic suppurative otitis media was studied. The specificity and accuracy were 89.5and 84.6.The tympanic membrane patching test was 57.590.Conclusion the tympanic cavity structure of the middle ear was treated by different angles of endoscopy. The results showed that the ossicular chain activity was in good agreement with the microscopic findings during the operation. It is of great clinical value to evaluate the ossicular chain lesions of chronic suppurative otitis media by using otoscope before operation.
