[Note on the variability of the basicranial axes]
Bulletin De L'Association Des Anatomistes
|September 1, 1978
Summary
Researchers identified the most stable basicranial axis for skull radiography. The nasion-opisthion axis and the auriculobregmatic Francfort plane are recommended for reliable anatomical measurements.
Area of Science:
- Anthropology
- Anatomy
- Radiology
Context:
- Accurate measurement of the basicranial axis is crucial in anatomical and anthropological studies.
- Previous studies have used various reference planes with differing degrees of reliability.
Purpose:
- To identify the most stable and least variable basicranial axis for use in lateral skull radiography.
- To evaluate the reliability of different anatomical landmarks and planes for measuring the basicranial axis.
Summary:
- Analysis of 114 lateral skull radiographies revealed that the foramen magnum plane and axes through the sellion point are too variable for precise measurement.
- The nasion-opisthion axis demonstrated less variability than the auriculobregmatic Francfort plane.
- However, the auriculobregmatic Francfort plane showed higher correlations with the bregma-nasiolambda angle, suggesting both planes are suitable for basicranial axis assessment.
Impact:
- Provides guidance for selecting the most reliable basicranial axis in radiographic studies.
- Aids in standardizing measurements for improved accuracy in anatomical and anthropological research.
- Contributes to a better understanding of skull morphology and its variations.
