Table 3. Average volumetric difference, the average surface, and average calculated movement of 24 patients in relevant face region.

Although the paranasal and upper lip region are forward, other areas are mostly backward.

Positive values of the surface distance indicate displacement in the forward direction and negative values indicate displacement in the backward direction.

S/H ratio is the ratio of soft tissue movement to hard tissue movement
