本文报道了对圆窗膜两方面的研究:(一)检查了大量的颞骨切片,挑选出病变累及圆窗膜或改变其功能的病例,包括耳硬化症、胆脂瘤、急性中耳炎和脑膜炎、Dow n综合征、Mondini综合征、圆窗膜膨出(外淋巴压力增加)、脑膜瘤等。这些标志说明若用手术清理这些病变可以导致圆窗膜的损伤和耳蜗性聋。(二)由于近年来经圆窗膜径路的手术增多,如耳蜗球囊造瘘术治疗美尼尔氏病、耳蜗埋植的电极插入;以及如何处理因窗膜破裂的突发性聋,作者用南美栗鼠作实验观察圆窗膜的早期愈合情况。18只动物36 This article reports on two aspects of round window films: (i) A large number of temporal bone sections were examined, and cases of lesions involving round window films or changes in their function were selected, including otosclerosis, cholesteatoma, acute otitis media and meningitis Dow n syndrome, Mondini syndrome, round window membrane bulging (increased perilymphatic pressure), meningiomas and the like. These signs indicate that surgery to clear these lesions can lead to round window membrane damage and cochlear deafness. (B) Due to the increase in the number of surgeries via round window membrane approaches in recent years, such as cochlear balloon ostomy for the treatment of Meniere’s disease and insertion of cochlear implants, and how to deal with sudden deafness due to rupture of the window membrane, South American chinchillas for experimental observation round window membrane early healing. 18 animals
