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.
