In children with complete unilateral cleft lip and palate, nasoalveolar molding was associated with better overall nasal aesthetics and improved cleft nostril height and cleft medial lip height at approximately 5 years of age.

Facial asymmetry assessment in skeletal Class III patients with spatially-dense geometric morphometrics. Y Fan, W He, G Chen, G Song, H Matthews, P Claes, R Jiang, T Xu.

Soft tissue asymmetry is predominately presented in the lower-third of the face in skeletal Class III patients and with various variations on other facial anatomical regions. Morphometric techniques and computer intensive analysis have allowed sophisticated quantification and visualization of the pointwise asymmetry on the full face.

This study applied the transfer learning model with a convolutional neural network based on 3-dimensional (3D) contour line features to evaluate the facial symmetry before and after OGS. A total of 158 patients were recruited in a retrospective cohort study for the assessment and comparison of facial symmetry before and after OGS from January 2018 to March 2020. Three-dimensional facial photographs were captured by the 3dMD face system in a natural head position, with eyes looking forward, relaxed facial muscles, and habitual dental occlusion before and at least 6 months after surgery.
