颜面对称性是记录颜面正常解剖形态和病理性畸形的重要标志之一。为了探讨中国正常(牙合)人颜面生理不对称的范围、规律及特点,本文运用莫尔条纹和计算机数字化处理技术对80名正常(牙合)青年人(40名男性,40名女性)颜面对称性进行了研究。结果表明,不显著的非对称性在正常人普遍存在,正常(牙合)人最大的不对称出现在颏部,男性为12.45%,女性为10.17%,其余部位均小于10%,最小不对称,女性出现在鼻尖,非对称率为6.20%,男性在上唇部,非对称率为7.67%。面下份颜面非对称率大于面上份,内侧大于外侧,男性大于女性。本研究数据可为临床颜面非对称性的诊断提供参考,同时,计算机图形数字化处理技术为莫尔条纹技术的临床应用提供了方便。
Facial symmetry is one of the important signs of normal facial anatomy and pathological deformity. In order to investigate the scope, regularity and characteristics of facial physiognomy asymmetry in Chinese normal occlusion, 80 normal occlusion young adults (40 males and 40 females) were treated with moire fringes and computerized digitization Symmetry was studied. The results showed that insignificant asymmetry was common in normal subjects. The largest asymmetry of normal occlusion occurred in the chin, with 12.45% in males and 10.17% in females, and less than 10% in the rest, with the smallest asymmetry , The females appeared at the tip of the nose, the asymmetry rate was 6.20%, and the male was in the upper lip, the unsymmetrical rate was 7.67%. Face under the facial asymmetry rate greater than the surface area, the medial greater than the lateral, men than women. The data of this study can provide a reference for the diagnosis of clinical facial asymmetry. At the same time, the digital processing technology of computer graphics provides convenience for the clinical application of moire fringe technology.
