OBJECTIVES/HYPOTHESIS: Medical imaging techniques have continually improved. However, measuring esthetic outcomes using conventional two-dimensional photography has inherent limitations visualizing in three dimensions such as the face.
This study used three-dimensional imaging to visualize facial images preoperatively and postoperatively in patients undergoing Contour threadlift procedures.
In patients undergoing Contour threadlift placement for midfacial rejuvenation, we prospectively imaged and photographed patients preoperatively and postoperatively. From three-dimensional images, we measured three-axis vector movement of the facial soft tissue in millimeters. Three control subjects (n = 6, bilateral sides) who had not undergone any procedure were a control group to confirm stability of the images over time. Patients also completed a questionnaire regarding their results and overall experience.
We studied 6 (n = 12, bilateral procedures) undergoing Contour thread placement. Analyzed images revealed a trend of midface soft tissue flattening of nasolabial contour over 3 months. Average nasolabial flattening or tightening was 2.3 mm (P > .05) in the Contour patient group. The flattening of the midfacial region returned to baseline postprocedure at 90 days. Three-dimensional imaging for the control subjects demonstrate less than 0.2 mm change (P < .05) in the nasolabial region weekly over a period of 3 weeks.
After 3 months, patients undergoing Contour thread placement had three-dimensional imaging measurements suggesting a return to baseline values. Three-dimensional imaging may increase accuracy in quantifying change after surgery specifically with contour differences; film and digital photography capture in only two dimensions. The use of three-dimensional imaging may be applicable to numerous clinical settings.
目的/假设:医学成像技术不断进步。然而,使用传统二维摄影测量美学效果在可视化三维物体(如面部)时存在固有局限性。
本研究使用三维成像技术对接受轮廓线提升手术患者的术前和术后面部图像进行可视化处理。
对于接受轮廓线提升术以改善中面部年轻化的患者,我们对其术前和术后进行了前瞻性成像和拍照。从三维图像中,我们以毫米为单位测量面部软组织的三轴向量移动。三名未接受任何手术的对照受试者(n = 6,双侧)作为对照组,以确认图像随时间的稳定性。患者还完成了一份关于其结果和总体体验的问卷。
我们研究了6名(n = 12,双侧手术)接受轮廓线植入的患者。分析图像显示,在3个月内鼻唇轮廓的中面部软组织有扁平化趋势。轮廓线治疗患者组鼻唇平均扁平化或收紧程度为2.3毫米(P > .05)。中面部区域的扁平化在术后90天恢复到基线水平。对照组受试者的三维成像显示,在3周的时间里,鼻唇区域每周变化小于0.2毫米(P < .05)。
3个月后,接受轮廓线植入的患者进行三维成像测量显示恢复到基线值。三维成像可能会提高手术(尤其是轮廓差异)后变化量化的准确性;胶片和数码摄影仅捕捉二维图像。三维成像的应用可能适用于众多临床环境。
