[Animal-experimental examinations on spontaneous regeneration of rhino-basic fractures and dura fistulas (author's transl)].

Small injuries of the dura of the rhino-basis often do not show unambiguous symptoms. Liquorrhoe may be absent or only be present for a short time. There are different conceptions of treatment: active surgical and conservative conceptions. It was proved by animal experiments that small gaps of the dura may close spontaneously by cicatrisation. The experimental results justify a conservative treatment in special cases.
