The anterior cranial base is considered the most stable area for evaluating craniofacial growth due to its specific anatomical and functional characteristics. This region contributes significantly to the overall stability of the craniofacial complex, serving as a crucial reference point for orthodontic and orthognathic analysis.

The anterior cranial base provides a solid foundation for the assessment of skeletal relationships and growth patterns over time. It is less subject to the changes induced by dental movements and other functional alterations that can affect other structures, such as the occlusal plane or the nasal floor. Because it is intimately associated with cranial structures that are stable and less influenced by soft tissue changes, measurements taken from the anterior cranial base can yield reliable insights into the growth and development of the face.

In contrast, areas such as the nasal floor or occlusal plane may be more affected by various factors, including dental treatment, functional changes, and soft tissue alterations. These factors can lead to variability that complicates the assessment of growth in those regions. Therefore, the anterior cranial base stands out as the most reliable site for evaluating craniofacial growth due to its relative stability over time.
