title: [The growth of the basis cranii (distances measured externally and problems of the asymmetry) (author's transl)].
abstract: The postnatal linear expansion in the region of skull base at the external cranial side was investigated at 91 skulls (44 adults, 47 children). From the anterior end of the Meatus acusticus externus to some anthropological measuring marks in the orbital region (Ektokonchion, Nasomaxillo-frontale, Dakryon, superior and inferior orbital rim) the growth increases between newborn age and 2 years. There is a phase of rest between 2 and 4 years, a further distance growth between 4 and 7 years, a phase of rest between 7 and 17 years and an increase of distance till the adult age. From the posterior end of the meatus acusticus externus to the Opisthocranion proves a less growth increase between newborn age and 2 years, a great one between 2 and 4 years and in the following time only a less growth of distance. Our results of the problem of asymmetries demonstrate that the lateral orbital rim on the right side stretches more dorsally than on the left side. Generally the posterior measuring distance on the right side is greater than on the left side too. The right Orbitale moreover stands lower on the right than on the left side. Opposite to a line from Basion to the Spina nasalis posterior founded by us also the right Porion stands lower significantly than the left one.
