This study aimed to provide average of standard values in planning orthognathic surgery in Asians.
Thirty-three Asians with well-balanced facial profile, combined with class I occlusion and stabilized condylar head were evaluated using lateral cephalograms.
Facial length (Nasion'-Menton') was 138.8 and 127.0 mm in male and female, respectively. Upper and lower lip length were 24.5 and 49.8 mm for male, and 22.2 and 45.1 mm for female, and maxillary incisor exposure was 2.0 and 4.0 mm in male and female, respectively. Nasolabial angle was 77.7° and 84.1° in male and female, respectively. Alar base, A point', and maxillary incisor were placed posteriorly to true vertical line by 10.6, 1.0, and 8.0 mm for male and 9.0, 0.8, and 6.9 mm for female. The horizontal distance between upper lip anterior and lower lip anterior was 2.1 mm for male and 2.6 mm for female, and the horizontal distance between A point' and B point' was 5.3 mm for male and 3.9 mm for female. Orbital rim' to A-point' was 12.4 and 11.3 mm in male and female, respectively. Pogonion' located posteriorly to glabella' by 2.7 mm for male and anteriorly to glabella' by 3.2 mm for female, and facial angle was 156.7° and 147.0° in male and female, respectively.
This quantitative analysis of facial profile in Asian will be helpful in evaluation of facial soft tissue and establishment of treatment plans for orthognathic surgery.
本研究旨在提供亚洲人正颌外科手术规划中的标准值均值。
使用头颅侧位片对33例面部轮廓匀称、I类咬合且髁突头稳定的亚洲人进行评估。
男性和女性的面长（鼻根点'-颏下点'）分别为138.8和127.0毫米。男性上唇和下唇长度分别为24.5和49.8毫米，女性分别为22.2和45.1毫米，男性和女性上颌切牙暴露度分别为2.0和4.0毫米。男性和女性的鼻唇角分别为77.7°和84.1°。男性鼻翼基底、A点'和上颌切牙相对于真垂线向后的距离分别为10.6、1.0和8.0毫米，女性分别为9.0、0.8和6.9毫米。男性上唇前缘与下唇前缘之间的水平距离为2.1毫米，女性为2.6毫米，男性A点'与B点'之间 的水平距离为5.3毫米，女性为3.9毫米。男性和女性眶缘'至A点'的距离分别为12.4和11.3毫米。男性颏前点'位于眉间点'后方2.7毫米处，女性位于眉间点'前方3.2毫米处，男性和女性的面角分别为156.7°和147.0°。
对亚洲人面部轮廓的这种定量分析将有助于面部软组织评估及正颌外科治疗计划的制定。
