BACKGROUND/PURPOSE: Studies have reported the advantages of digital imaging-assisted orthognathic surgery planning, but there is scarce information about a full digital planning modality. This study evaluated the 3D cephalometric-based and patient-reported outcomes of a full digital workflow for orthognathic surgery planning in the treatment of asymmetric maxillomandibular disharmony.
A postoperative 3D image dataset of 30 Taiwanese Chinese patients with asymmetric skeletal Class III deformities who underwent full digital planning for two-jaw surgery were retrieved from the authors' database. The 3D cephalometric data (dental, skeletal, and soft tissue evaluations) were compared to the ethnicity-matched 3D cephalometric normative values. Patient-reported outcome measure tools regarding postoperative overall appearance and satisfaction with facial areas (ranging from 0 to 100 and 0 to 10, respectively) were administered. The number of needed or requested revisionary surgery was collected.
No difference (all p > 0.05) was observed between the orthognathic-surgery-treated patients and the normative value for most of the tested 3D cephalometric parameters, with the exception (p < 0.05) of three mandible and occlusal-plane-related parameters. Both patient-reported outcome measure tools showed that patients' satisfaction with their postoperative appearance was high for overall face (89.7 ± 4.5) and specific facial regions (nose, 7.1 ± 1.3; lip, 8.3 ± 1.6; upper gum, 8.5 ± 1.2; cheek, 8.8 ± 1.1; chin, 9.2 ± 1.2; and teeth, 9.3 ± 0.8), with no need for revisionary surgery.
The patients treated with a full 3D digital planning-assisted two-jaw surgery had a similar 3D dental relation, facial convexity, and symmetry compared to healthy ethnicity-matched individuals, and they reported higher satisfaction levels with their postoperative facial appearance results.
背景/目的：已有研究报告了数字化影像辅助正颌手术规划的优势，但对于全数字化规划方式的信息却很少。本研究评估了一种全数字化流程在治疗不对称上颌下颌骨不调中的 3D 头影测量及患者报告结果。
从作者的数据库中检索了 30 例台湾汉族因骨骼 III 类不对称畸形而接受双颌手术全数字化规划的患者的术后 3D 图像数据集。比较了 3D 头影测量数据（牙、骨和软组织评估）与种族匹配的 3D 头影测量正常值。使用患者报告的术后整体外观和对面部区域满意度的测量工具（分别为 0 到 100 和 0 到 10）进行评估。收集了需要或要求进行修正手术的次数。
在大多数测试的 3D 头影测量参数中，接受正颌手术治疗的患者与正常值之间没有差异（均 p＞0.05），除了三个下颌和咬合平面相关的参数（p＜0.05）。两种患者报告的测量工具均显示，患者对整体面部（89.7±4.5）和特定面部区域（鼻子，7.1±1.3；嘴唇，8.3±1.6；上牙龈，8.5±1.2；脸颊，8.8±1.1；下巴，9.2±1.2；牙齿，9.3±0.8）的术后外观满意度很高，不需要进行修正手术。
接受全 3D 数字化规划辅助双颌手术治疗的患者与健康的种族匹配个体相比，具有相似的 3D 牙齿关系、面部凸度和对称性，并且对术后面部外观结果的满意度更高。
