目的:通过软与半软微窥镜对耳蜗鼓阶检查,探讨软与半软微窥镜对内耳检查的效果。方法:选择15例人工耳蜗手术患者,在打开耳蜗后,使用1mm直径半软微窥镜到达耳蜗鼓阶内9mm深度,0.5mm软窥镜到达耳蜗鼓阶内25mm深度,进行耳蜗内检查,术中录像,将检查效果进行比较。结果:15例患者,先使用0.5mm直径软微窥镜到达耳蜗鼓阶内15~25mm深度,全程清晰度较差,不能发现耳蜗内细微结构;使用1mm直径半软微窥镜到达耳蜗鼓阶内9mm深度,发现3例耳蜗鼓阶内侧骨螺旋板有钙化物沉积,1例耳蜗鼓阶外侧壁见肉芽样软组织,其余11例未发现耳蜗鼓阶内病变。结论:0.5mm直径软微窥镜检查耳蜗鼓阶,可达到耳蜗内2圈的深度,但清晰度较差,难以发现耳蜗鼓阶内的病变;1mm直径半软微窥镜可以清晰地辨认耳蜗鼓阶内表面结构,发现病变,但达到的深度仅为9mm左右,无法进行耳蜗全程检查。
Objective: To investigate the effects of soft and semi-soft endoscope on the examination of the inner ear through soft and semi-soft endoscopes. Methods: Fifteen patients undergoing cochlear surgery were selected. After the cochlear was opened, the depth of 9mm was reached by using a 1mm diameter semi-soft micro-scope and reached the depth of 25mm in the scala tympani. In the video, will check the effect of comparison. Results: In 15 patients, the diameter of the cochlear implants was reached to 15 ~ 25mm depth with 0.5mm soft soft endoscope. The sharpness of the cochlea was poor and the microstructure of the cochlea could not be found. The 1mm diameter soft soft endoscope reached the cochlea of the cochlea Within 9mm depth, we found that there were calcified deposits in the medial spine of the cochlear scaffolds in 3 cases, granulation-like soft tissue in 1 case on the outer side of the scala tympani, and the other 11 cases did not find lesions in the cochlea. CONCLUSIONS: 0.5 mm diameter soft microscopic examination of the cochlea of the cochlea can achieve a depth of 2 turns in the cochlea, but its resolution is poor, making it difficult to detect lesions in the cochlea of the cochlea. A 1 mm diameter semi-soft microscope can clearly identify the cochlea Drum surface structure, found lesions, but reached a depth of only about 9mm, unable to conduct a full examination of the cochlea.
