[On the practical-medical mean distances of the fossa cranialis media].
The postnatal growth from different structures would be investigated at 61 skulls of children and 87 skulls of adults. The mean distance between the Foramen caecum and the Protuberantia occipitalis interna (internal length of the skull) increases from 9.7 cm to 14.0 cm. The greatest internal width of the skull grows up in the mean from 6.8 cm to 12.9 cm. The mean surface area of the Fossa cranialis media includes 7.6 cm2 by newborns and 22.4 cm2 by adults. The surface area of the right Fossa cranialis media is significantly more extensive than the left one. The mean radius of the curvature of the Ala minor ossis sphenoidalis increases from 11.8 mm to about 26,0 mm. The side angle of the Ala minor ascends from 75.7 degrees to about 84 degrees in a detour way. The bight to be found underneath for the Polus temporalis has a mean surface area of 24 mm2 in the newborns and 64 mm2 in the adults. The deepest zone of the floor of the Fossa cranialis media is to be located in newborns in the mean 2 mm and in adults in the mean 0.4 mm below the Frankfort plane and 6.4 mm dorsal of the Tuberculum articulare. The mean distance to the Processus zygomaticus cornes to 4.5 mm in newborns and 0.9 mm in adults. The Fossa temporalis deepens in all measured zones during the postnatal development. Apart from the right-left-differences the acceleration during the last 150 years and the sexual dimorphismus of the skull will be discussed.
