2019 Annual Session Conference

Three-dimensional Evaluation of Facial Asymmetry in Growing Patients

May 4, 2019 1:35pm ‐ May 4, 2019 2:05pm


Diagnosis of facial asymmetry is routinely based on the analysis of patient' s facial photography by determining a symmetry plane and measuring linear and planar differences between the two hemifaces. As it is very difficult to evaluate facial asymmetry in small growing children from facial photography, constructing two mirror facial halves is one possibility of the assessment. However, the main drawback of this method is that facial photographs show a 3D structure in two dimensional perspective, the landmarks used to define the facial midline and to construct the symmetry plane can not be exactly defined, and thus, the precision of the method is highly questionable. PA involves irradiation risk and is therefore not appropriate to be used in small growing children. The use of three-dimensional method will be described to evaluate facial asymmetry in growing children.

Learning Objectives:

  • Diagnose three-dimensional facial asymmetry in growing patients.
  • Define characteristics of facial asymmetry three-dimensionally.
  • Propose contemporary diagnostics of facial asymmetry in growing patients based on non-invasive stereophotogrammetry methodology.
