Abstract
Menton (Me) deviation is commonly used for diagnosing faical asymmetry. This study compared angle and distance measurement in determining the severity of Me deviation for facial asymmetry diagnosis. Three-Dimensional Computed Tomographic(3D CT) images of 32 patients with facial asymmetry were selectedfor this study. Angle and distance of Me deviation in each patient were obtained and the severity of Me deviation was determined according to the angle and the distance measurement. The severity of Me deviation by angle and distance measurement was compared and statistical analysis was performed. Eight (25%) showed disagreement in severity of Me deviation between the two measurements. The kappa coefficient on the two measurements was 0.67, showing substantial agreement.
Angle and distance measurement are useful in determining severity of Me deviation on 3D CT. It is suggested that both angle and distance measurement be performed in determining severity of Me deivation.
