SOFT-TISSUE FACIAL ASYMMETRY BEFORE AND AFTER ORTHOGNATHIC SURGERY:
APPLICATION OF A NEW 3D PROTOCOL
Table 1. Time-related variations in facial asymmetry in the analysed
patient (mm). The larger the value, the more asymmetrical the patient.

Figure 3. Z-scores of the analysed patient during the 24-months follow
up.
z-score value calculated in pre-surgical acquisitions was
1.28 SD for the lower third, 1.79 SD for the middle third
and 0.38 SD for the upper third; 24 months after surgery
the z-score was 0.52 SD for the lower third, 0.18 SD for
the middle and 0.37 SD for the upper one.
