Abstract
-
PURPOSE: This study aimed to identify the range of normal facial asymmetry using three-dimensional CT and to
develop a simple method of diagnosis of facial asymmetry.
MATERIALS AND METHODS
Twenty eight adults with normal occlusion (16 males and 12 females; mean age 24 years and 1 month) were selected, whose faces were assessed to be symmetric by an orthodontist. Three-dimensional reconstructions were obtained utilizing spiral CT scans and an oral and maxillofacial radiologist evaluated nineteen anatomic landmarks in three-dimensional coordinates. Facial asymmetry index of each landmark was caluculated.
RESULTS
The range of normal facial asymmetry of each landmark was identified using mean and standard deviation of facial asymmetry index.
CONCLUSION
The range of normal facial asymmetry identified in this study may be used as a diagnostic standard for facial asymmetry analysis.
