The S-depth is specifically used to assess the depth of the facial profile from the nasion (the bridge of the nose) to the incisor region. This measurement provides valuable information regarding the facial aesthetics and the spatial relationships of the facial structures. In cephalometric analysis, understanding the depth of the facial profile is critical for diagnosis and treatment planning, particularly in orthodontics and orthognathic surgery. A deeper S-depth may indicate certain skeletal or dental relationships that could influence treatment decisions or the need for surgical intervention.

Assessing this depth helps clinicians evaluate facial balance and harmony and to determine if adjustments are necessary to enhance the aesthetic outcome.
