AN APPLIED MORPHOMETRIC STUDY OF THE ANTERIOR CRANIAL FOSSA / 解剖学报

ABSTRACT

The morphometric value of the anterior cranial fossa has previously been poorly documented. There is also an absence of information about the asymmetry between the two halves of this fossa. In a series of 100 Chinese adult cranial bases at random, distances from each selected osseous point to a particular plane or distances between osseous points were measured, All these points, except the frontozygomatic point only, are endocranially situated, and data on 17 variables were available for statistical analysis. As a result, the right half shows some greater sagittal values than that of the left, and the width from the frontozygomatic point to the median sagittal plane is greater on the right half than that on the left, the differences are statistically significant or highly significant. Moreover, more of the sagittal measurements on the right side Correlate significantly with the right-left measurements. Accordingly, the two halves of the anterior cranial fossa is asymmetrically designed. Problems relating to the line of demarcation between the median portion of the anterior and middle cranial fossae, as well as the possible eraniocerebrum relationship and clinical considerations are discussed.
