Photographic standards issued by the Plastic Surgery Educational Foundation ensure accurate comparisons between preoperative and postoperative imaging. These standards, however, do not properly display the circumferential body ptosis seen in massive weight loss (MWL) patients. Photographic standardization for massive weight loss patients is needed for patient consultation, surgical planning, and accurate analysis and comparison of postoperative results.
A 10-year review of the photographic standards used for MWL patients at the University of California Davis Medical Center were reviewed and compared to current photographic standards in plastic surgery and clinical photo documentation seen in the literature for body contouring after MWL. Evaluation of arm position in obscuring the evaluation of circumferential ptosis in the upper and lower body was performed.
Current photographic standards in plastic surgery do not capture the circumferential ptosis often seen in MWL patients, and there are no consistent modifications or standards recommended for MWL patients. Arm position was noted to affect shadowing and obstruction as well as distortion of circumferential excess. During the first 5 years reviewed, initial consultations included 8 images captured at 45-degree increments with the arms abducted to 90 degrees to document the circumferential excess from shoulders to the knees (Total Body, Fig. 1). They also included 8 images focused on the lower body (Fig. 2) and 8 images focused on the upper body. This required a total of 24 images captured per consultation. During the latter 5 years reviewed, the 8 Total Body images continued to be captured whereas the 16 images focusing on the upper and lower body have been discarded and replaced with 10 images (Fig. 3), captured from shoulders to knees at 45-degree increments with arms positioned behind the back (5) and in the lap (5) for a total of 18 images captured per consultation.
Currently there are no photographic standards for MWL patients that accurately capture their circumferential ptosis. All arm positions affect the evaluation of the circumferential excess to some degree, thus any choice of arm position represents a compromise between visibility and distortion of anatomy. Having considered these issues, we recommend the use of 360-degree clinical photo documentation obtained at 45-degree increments with arms abducted to 90 degrees to capture the total body. We have discarded focused upper and lower body images as these are visible in the Total Body images, thus decreasing patient fatigue and discomfort from excessive pictures. As techniques in post-bariatric body contouring have improved, we now routinely compare our results to non-post-bariatric body contouring patients and thus have added more standard arm positioning to facilitate these comparisons.
整形外科学教育基金会发布的摄影标准可确保术前和术后影像的准确对比。然而,这些标准无法恰当地呈现出肥胖症患者大量减重后出现的全身皮肤松弛现象。对于肥胖症患者,需要进行摄影标准化,以用于患者咨询、手术规划以及术后结果的准确分析和比较。
回顾了加利福尼亚大学戴维斯分校医学中心用于肥胖症患者的摄影标准,并将其与整形手术中当前的摄影标准以及文献中所见的肥胖症患者身体塑形后的临床照片记录进行比较。评估了手臂位置对遮挡上下半身环形皮肤松弛评估的影响。
整形手术中当前的摄影标准无法捕捉肥胖症患者常见的环形皮肤松弛情况,且没有针对肥胖症患者推荐的一致的修改方法或标准。注意到手臂位置会影响阴影、遮挡以及环形多余皮肤的变形。在回顾的前5年中,初次咨询包括以45度增量拍摄的8张图像,手臂外展至90度,以记录从肩部到膝盖的环形多余皮肤(全身,图1)。还包括8张聚焦于下半身的图像(图2)和8张聚焦于上半身的图像。每次咨询总共需要拍摄24张图像。在回顾的后5年中,继续拍摄8张全身图像,而聚焦于上半身和下半身的16张图像被舍弃,取而代之的是10张图像(图3),以45度增量从肩部到膝盖拍摄,手臂置于背后(5张)和大腿上(5张),每次咨询总共拍摄18张图像。
目前尚无准确捕捉肥胖症患者环形皮肤松弛情况的摄影标准。所有手臂位置都会在一定程度上影响对环形多余皮肤的评估,因此手臂位置的任何选择都代表着在解剖结构的可见性和变形之间的权衡。考虑到这些问题,我们建议使用以45度增量、手臂外展至90度拍摄的360度临床照片记录来捕捉全身情况。我们舍弃了聚焦于上半身和下半身的图像,因为这些在全身图像中可见,从而减少了患者因过多照片而产生的疲劳和不适。随着减重后身体塑形技术的改进,我们现在常规地将我们的结果与非减重后身体塑形患者进行比较,因此增加了更多标准的手臂位置以方便这些比较。
