Significant differences (P < 0.05) were also identified in the remaining 6 soft tissue measurements, with average deviations no greater than 0.5 mm (linear measurement) or 1.2° (angular measurements).Ī 3D face modeling method based on 2D face photos was revealed and validated. A significant difference (P < 0.05) of approximately 1.5 mm was found for facial height. The average root mean square errors between face scan models and reconstructed models at perioral area (1.26 ± 0.24 mm, 95%CI: 1.15–1.37 mm) were significantly smaller than the entire facial area (1.77 ± 0.23 mm, 95%CI:1.67–1.88 mm), P Z > X, P < 0.01). The reconstructed 3D face models showed good facial morphology with fine texture. The accuracy of the landmarks in different dimensions was determined, and twelve facial soft tissue measurements were compared to validate the clinical potential of the method. After preprocessing and repositioning, 3D deviation analysis was performed. Various facial landmarks were finely adjusted manually to refine the models. Twenty-three patients were included, and Character Creator v3.2 software with the Headshot v1.0 plugin was used for 3D face model reconstruction. This study aims to investigate the accuracy of a three-dimensional (3D) face reconstruction method based on conventional clinical two-dimensional (2D) photos.
