After dealing in detail with the literature appeared since 1888, 3 observations by the author are discussed. These cases were congenital fissurations on the frontal base of the skull. Some cases developed clinical phenomena with increases of the intracranial pressure (convexity meningioma). The diagnosis is defined in a strict manner. All forms of direct arrorions by frontobasally located tumours or in combination with hyhpophyseal tumours as well as craniopharyngiomas are left out of consideration. They cannot be considered as spontaneous liquor fistulas. The well-known diagnostic and therapeutic measures are dealt with briefly.
在详细探讨了自1888年以来出现的文献后，讨论了作者的3例观察病例。这些病例是颅骨额底部的先天性裂隙。有些病例出现了颅内压升高的临床现象（凸面脑膜瘤）。诊断有严格的定义。位于额底部的肿瘤或与垂体肿瘤以及颅咽管瘤相关的所有直接异常形式均不在考虑范围内。它们不能被视为自发性脑脊液瘘。文中简要介绍了一些众所周知的诊断和治疗措施。
