众所周知,某些类型的中耳炎,不仅会引起内耳的灾难性变化,而且能引起难于捉摸的耳蜗病理性和功能性改变。本文用猫作实验,由人为的咽鼓管阻塞引起中耳炎,对圆窗和卵圆窗膜的组织病理改变作了连续的观察。发现圆窗膜的病理变化是渐进性的,与中耳粘骨膜的变化类似,膜的通透性一致,启示圆窗膜很可能是中耳和内耳的一个通道。作者将32个健康成年猫,用无菌的硅海绵经腭堵塞左咽鼓管,右侧作对照。然后在第1、3
It is well-known that certain types of otitis media not only cause catastrophic changes in the inner ear, but also cause elusive pathological and functional changes in the cochlea. In this paper, experiments with cats, induced by artificial eustachian tube obstruction caused by otitis media, the round window and the oval window of the histopathological changes made a continuous observation. Found that the pathological changes of the round window membrane is gradual, similar to the change of middle ear mucoperiosteum, membrane permeability, suggesting that the round window membrane is likely to be a channel in the middle ear and inner ear.
