The author had the opportunity to observe the progressive development of a special form of basilar impression characterized by transitory supplementary fissure of the basi-occipital bone, persistence of the spheno-occipital synchondrosis and hypoplasia of the basi-occipital. He proposes to dissociate the general concept of basilar impression and to consider anatomo-clinical entities such as the example described in this paper.
作者有机会观察到一种特殊形式的基底凹陷的进展性发展，其特征为枕骨基部的暂时性补充裂隙、蝶枕软骨结合的持续存在以及枕骨基部发育不全。他提议将基底凹陷的一般概念区分开来，并考虑解剖学 - 临床实体，如本文所述的例子。
