Abstract

This study was aimed at how posteroanterior cephalometric measurements affect the perception of the patient about his/her facial asymmetry. One hundred orthodontic patients, over the age of 12, who required a posteroanterior cephalogram in the Department of Orthodontics of Chonnam National University Hospital were used as the subjects. They were asked if they thought their faces were asymmetrical. Their responses were classified into 5 groups based on the level of asymmetry as follows : Definitely No, Probably No, Don't Know, Probably Yes, and Definitely Yes. Nine linear and four angular measurements from each posteroanterior cephalometric radiographs were analysed on the standard of the line between crista galli and anterior nasal spine to show the extent of asymmetry. Through this comparative study, the following results were obtained. 1. As the deviation of menton and the midline discrepancy of the upper and lower jaws were greater, the perception of patients about their facial asymmetry was higher. 2. All the measurements from the group "Don't Know" showed no statistical difference from those of the groups "Definitely No" or "Probably No." 3. All the measurements from the group "Probably Yes" showed no statistical difference from those of the group "Definitely Yes."
