摘要：

目的　探索 3D 测量技术在鼻整形术测量和评估中的应用效果。方法　术前应用 3D 扫描仪采集患者全面部影像并行三维重建，通过 3D 设计方案及测量数据指导术中假体雕刻及制定手术方案。术中再次进行 3D 测量，保证术后即时效果与术前设计效果的高度吻合。术后 1~6 个月再次 3D 测量，选取 7 个美学标志点，将术中、术后 3D 扫描数据与术前 3D 模拟数据比对，并进行统计学分析。结果　本组共 31 例鼻整形患者，30 例对术后效果满意，1 例术后出现鼻背假体歪斜，行二期手术修复后效果满意。通过分析鼻部 7 个美学标志点数据的样本置信水平，获得一个样本统计值与总体参数值之间的误差范围，用以判断术中、术后效果与术前模拟效果的吻合程度，即合格标准。所有病例术中和术后的监测数据均在样本统计的置信水平的误差范围内，符合术前模拟效果的标准。结论　3D 扫描技术在术中的应用保证了术后效果与术前模拟效果的吻合，对于鼻整形的质量控制非常有效。

Abstract:

Objective To explore the application effect of 3D imaging technology in the measurement and evaluation of
rhinoplasty. Methods Before operation, facial images of beauty seekers were collected by 3D scanner and three-dimensional
imaging was performed. The surgical plan was formulated by 3D design scheme and measurement data, and the intraoperative
prosthesis carving was guided and the operation was completed. The 3D measurement was performed again during the operation
to ensure that the immediate postoperative effect was highly consistent with the preoperative design effect. 3D measurements
were taken again 1 to 6 months after operation. Seven aesthetic landmarks were selected, and the intraoperative and postoperative
3D scanning data were compared with the preoperative 3D simulation data, and statistical analysis was carried out. Results
A total of 31 cases of cosmetic rhinoplasty were selected in this group, of which 30 cases were satisfied with the postoperative
results, and 1 case had implant deflection after operation, and the result was satisfied after the second stage of surgical repair.
By analyzing the sample confidence level of the data of 7 aesthetic landmarks in the nose, the error range between the sample
statistical value and the overall parameter value was obtained, which was used to judge the degree of coincidence between the
intraoperative, postoperative effects and the preoperative simulation effects, that is, the eligibility criteria. The intraoperative
and postoperative monitoring data of all cases were within the error range of the confidence level of the sample statistics, which
met the standard of preoperative simulation effect. Conclusion The application of 3D scanning technology in surgery ensures
that the postoperative effect is consistent with the preoperative simulation effect, which is very effective for the quality control of
rhinoplasty.
