To verify changes in facial soft tissue using the RadiANT-DICOM-viewer and Dolphin Imaging software, through linear measurements of tomographic points in a 3D reconstruction of the face and volumetric evaluation with three-dimensional measurements of the upper airways of patients with transverse maxillary discrepancy undergoing Surgically Assisted Rapid Maxillary Expansion (SARME).
Retrospective, transverse, and descriptive study, through the analysis of computed tomography scans of the face of patients with transverse maxillary discrepancy, treated from July 2019 to December 2022. The sample consisted of 15 patients of both sexes, aged 21-42 years old, who underwent surgically assisted rapid maxillary expansion using the transpalatal distractor. Analysis was performed through linear, angular, and three-dimensional measurements in millimeters, in the preoperative and late four-month postoperative period, in frontal 3D tomographic images of the face, in the region of the width of the nose and alar base and also angular measurement in the lateral tomography for the angle nasolabial and upper airways of rhinopharynx, oropharynx and hypopharynx.
There was an increase in nasal width with an average of 1.3467mm and an increase in the alar base with an average of 1.7333mm. A significant difference was found in the pre- and postoperative assessments of the measurements of nasal width, alar base and nasolabial angle, as well as the upper airways in all their extension. The results favour a better understanding of the professional and the patient regarding the diagnosis and management of patients with transverse maxillary width discrepancies.
Although our study shows an increase in soft tissues after SARME, no aesthetic changes are observed clinically, and all patients report significant respiratory improvement. SARME may therefore contribute to the improvement of professionals working in the field of oral and maxillofacial surgery and orthodontics.

通过对头面部三维重建中断层点的线性测量以及对上颌横向差异患者行手术辅助快速扩弓（SARME）后的上气道的三维测量，利用 RadiANT-DICOM-viewer 和 Dolphin Imaging 软件验证面部软组织的变化。
回顾性、横向和描述性研究，通过分析 2019 年 7 月至 2022 年 12 月间患有上颌横向差异的患者的头面部计算机断层扫描。样本包括 15 名 21-42 岁的男女患者，他们均接受了经口腭裂扩张器的手术辅助快速扩弓治疗。分析在术前和术后四个月的晚期进行，通过面部分层 3D 断层图像，对鼻宽和鼻翼基底的线性、角度和三维测量，以及鼻唇角的侧位断层角度测量和鼻咽、口咽和下咽的上气道进行。
鼻宽平均增加 1.3467mm，鼻翼基底平均增加 1.7333mm。在术前和术后的鼻宽、鼻翼基底和鼻唇角测量以及上气道所有延伸部分的评估中，均发现有显著差异。结果有助于专业人员和患者更好地理解上颌横向宽度差异患者的诊断和治疗。
尽管我们的研究表明 SARME 后软组织增加，但临床上未观察到美观变化，所有患者均报告呼吸明显改善。因此，SARME 可能有助于改善从事口腔颌面外科和正畸学领域的专业人员的工作。
