To describe common patterns of facial asymmetry and to augment the facial analysis paradigm for improved preoperative counseling and surgical planning.
We conducted a frontal photographic analysis of 50 patients who were seeking various types of facial cosmetic surgical procedures. The horizontal zonal thirds of the face were analyzed, and the bilateral data points were compared in regard to brow height, width of midface at maximum distance, malar eminence height,nasal alar height, and mandible width measured from the oral commissure to the gonial angle.
Forty-five patients demonstrated measurable asymmetry of the midface. The malar eminence was found to be more superiorly positioned and defined on the narrower side of the face in all cases. In contrast, the contralateral wider side of the face appeared flatter, with a more hypoplastic, inferiorly positioned malar eminence.Also, the wider side of the face more often demonstrated a wider mandibular dimension and a superiorly displaced ala. The upper third of the face, in regard to brow height, was the most variable and showed little correlation to the lower two-thirds of the face.
This facial analysis exercise can assist the surgeon in (1) preoperative counseling, (2) managing expectations,(3) choosing appropriate-sized implants for improved symmetry, and (4) offering a more detailed assessment during the counseling of patients before faceliftsurgery
描述常见的面部不对称模式，并增强面部分析范式，以改善术前咨询和手术规划。
我们对 50 名寻求各种面部美容手术的患者进行了正面摄影分析。对面部的水平分区三分之一进行了分析，并比较了双侧数据点在眉高、中面部最大距离处的宽度、颧骨突出高度、鼻翼高度和从口腔口角到下颌角的下颌宽度方面的差异。
45 名患者的中面部存在可测量的不对称。在所有情况下，颧骨突出都位于更上方和更窄侧的面部，而对面较宽的一侧则显得更平坦，颧骨突出更小，位置更低。此外，较宽侧的面部更常表现为下颌宽度较宽和鼻翼上移。就眉高而言，面部的上三分之一是最可变的，与面部的中下三分之一相关性较小。
这种面部分析练习可以帮助外科医生：（1）术前咨询，（2）管理期望，（3）选择合适大小的植入物以改善对称性，以及（4）在面部提升手术前为患者提供更详细的评估。
