Facial thirds−based evaluation of facial asymmetry using stereophotogrammetric devices: Application to facial palsy subjects

Many conditions can compromise facial symmetry, resulting in an impairment of the affected person from both esthetic and functional points of view. For these reasons, a detailed, focused, and objective evaluation of facial asymmetry is needed, both for surgical planning and for treatment evaluation.In this study, we present a new quantitative method to assess symmetry in different facial thirds, objectively defined on the territories of distribution of trigeminal branches.A total of 70 subjects (40 healthy controls and 30 patients with unilateral facial palsy) participated.
