The Use of Digital Imaging in the Evaluation of Perception in Facial Asymmetry Caused by Facial Nerve Disorders

摘要

Facial asymmetry may be caused by facial nerve dysfunctions, as in the case of facial paralysis. The aim of this study is to evaluate the usefulness of manipulated digital images in facial paralysis diagnosis, to determine facial attractiveness, emotional perception and the level of knowledge among students of the Faculty of Dentistry. The results show that facial symmetry plays an important role in assessing facial attractiveness, and emotional perception is influenced by the presence of smile or smile mimicked by the asymmetrical pulling of the oral commissure. In conclusion, manipulated digital facial images facilitate the diagnosis of facial palsy or paralysis. On the other hand, these images are partially impersonal and cannot accurately convey the emotional experiences of the subjects.
