Surgical correction of facial asymmetry is commonly performed in at least two stages. Recently, because of the long duration of a two-step procedure, the demand for a one-step procedure has increased. Our study aims to present a fully digitalized workflow for one-stage mandibular contouring (MC) and bimaxillary surgery to correct severe facial asymmetry using 3D technology.
A retrospective monocentric study was conducted for all patients affected by severe facial asymmetry who had undergone MC and orthognathic surgery between January 2018 and June 2020 at the Face Surgery Center, in Parma, Italy.
The final study sample included 20 patients (12 women and 8 men). The mean age of the patients at the time of surgery was 20.8 years (range: 18-25 years). At the one-year follow-up, all patients had stable occlusion with a symmetric face. Mandibular angle degree (Ar-Go-Me) increased significantly from 113. 6° to 122.7° at the left side and from 113.3° to 122.7° at the right side (p < 0.05) (Table 1). The mandibular width (Go-Go) decreased from 116.5 to 106.4 mm (p < 0.05).
A fully digitalized workflow for one-stage MC and bimaxillary surgery is a safe and valid option to correct facial asymmetry. CAD CAM technology is an indispensable tool to obtain predictable results.

面部不对称的外科矫正通常至少分两个阶段进行。近来，由于两步法手术时间长，对一步法手术的需求增加。我们的研究旨在提出一种全数字化工作流程，用于一期下颌轮廓塑形（MC）和双颌手术，以使用3D技术矫正严重面部不对称。
对2018年1月至2020年6月期间在意大利帕尔马面部手术中心接受MC和正颌手术的所有严重面部不对称患者进行了一项回顾性单中心研究。
最终研究样本包括20例患者（12名女性和8名男性）。手术时患者的平均年龄为20.8岁（范围：18 - 25岁）。在一年的随访中，所有患者咬合稳定，面部对称。左侧下颌角度数（Ar - Go - Me）从113.6°显著增加至122.7°-，右侧从113.3°增加至122.7°（p < 0.05）（表1）。下颌宽度（Go - Go）从116.5减小至106.4 mm（p < 0.05）。
一期MC和双颌手术的全数字化工作流程是矫正面部不对称的一种安全有效的选择。CAD CAM技术是获得可预测结果必不可少的工具。
