Studies of Relationship between P-A Cephalometric Measurements and Vidual Facial Asymmetry / 체질인류학회지

ABSTRACT

The degree of facial asymmetry in P -A cephalogram may differ from that we felt in clinical examination. The purpose of this study was to find out the P -A cephalometric measurements affecting the visual facial asymmetry. Fifty four adult patients who had been diagnosed as the facial asymmetry in clinical examination were selected for this study. Through the analysis of facial photograph and P -A cephalogram, the following results were obtained 1. In linear measurements, Me (Menton) to MSR (Mid -sagittal reference line), Cd (Condylion) to Me, Ag (Antegonion) to Me, and Ag to MSR were significantly related with facial asymmetric index. 2. In angular measurements, angle Cg -Me plane to MSR, angle ANS -Me plane to MSR, and angle Cd - Ag -Me were significantly related with facial asymmetric index. Especially, angle Cg -Me plane to MSR, angle ANS -Me plane to MSR were highly related. 3. In surface measurements, Cg -Ag -Ag ' and Cd -Ag -Me -Cd ' were significantly related with facial asymmetric index. The results of this study suggested that menton point was the most affected landmark in visual facial asymmetry.
