The clinical findings concerning the diagnosis of a rupture of the round window membrane vary widely. Therefore, microtopography of the round window was studied using 45 serially sectioned human temporal bones of the Wittmaack Collection, ENT Clinic, University of Hamburg. Our morphometrical data show a great variety in respect of the dimension of the round window membrane and the angle between the window membrane and the tympanic membrane. The extension and the microtopography of the promontory are as variable as the mucosal folds in the round window niche. It can be concluded that a direct view of the round window membrane is possible only in rare cases. Surgical manipulations to improve the view of the round window should be avoided because of the danger of an iatrogenic lesion of the inner ear.
关于圆窗膜破裂诊断的临床发现差异很大。因此，我们使用了汉堡大学耳鼻喉科诊所维特马克收藏的45块连续切片的人类颞骨，对圆窗的微观结构进行了研究。我们的形态学数据显示，圆窗膜的尺寸以及窗膜与鼓膜之间的角度存在很大差异。岬的范围和微观结构与圆窗龛内的黏膜皱襞一样多变。可以得出结论，只有在极少数情况下才能直接看到圆窗膜。由于存在内耳医源性损伤的风险，应避免进行旨在改善圆窗视野的手术操作。
