To determine if there are aesthetic differences in patients who have undergone a SMAS lifting with predominantly oblique-horizontal vectors versus predominantly oblique-vertical vectors. To determine if there are aesthetic differences in the results of the neck using sutures placed in specific areas of the platysmal muscle versus randomly placed sutures for platysmal plication to the mastoid. Comparative, retrospective, blind, and randomized study. Evaluation of preoperative and postoperative photographs of 54 patients who underwent predominantly oblique-horizontal SMAS lifting versus 53 patients who underwent predominantly oblique-vertical traction of the SMAS flap, reviewed by three external, unbiased facial plastic surgeons in a blind study. A 7-point scale was used to grade the improvement of the face and the neck. In the face, SMAS lifting with predominantly oblique-vertical vectors used during the procedure offer statistically better results ( ≤ 0.001) in comparison to predominantly oblique-horizontal vectors in the aesthetical improvement of the malar eminence, melolabial fold and jowls. In the neck, both techniques offer excellent results, but the sutures used for platysmal plication in specific areas offer no statistical differences in aesthetical results from those sutures that are randomly placed in the platysmal muscle. In our study of 107 patients, SMAS lifting using predominantly oblique-vertical vectors seem to have better results than using predominantly oblique-horizontal vectors. For the neck, we do not find statistical differences between randomly placed sutures for platysmal plication versus sutures placed in specific areas of the muscle.
确定在接受主要为斜向水平向量与主要为斜向垂直向量的SMAS提升术的患者之间是否存在美学差异。确定在颈阔肌特定区域放置缝线与随机放置缝线进行颈阔肌折叠至乳突的颈部手术结果中是否存在美学差异。比较性、回顾性、盲法和随机研究。对54例主要接受斜向水平SMAS提升术的患者与53例主要接受SMAS瓣斜向垂直牵引术的患者的术前和术后照片进行评估，由三位外部、无偏见的面部整形外科医生在盲法研究中进行审查。使用7分制对面部和颈部的改善情况进行评分。在面部，与主要为斜向水平向量相比，手术过程中主要使用斜向垂直向量的SMAS提升术在改善颧突、鼻唇沟和下颌赘肉的美学效果方面具有统计学上更好的结果（≤0.001）。在颈部，两种技术都能提供出色的效果，但在颈阔肌特定区域使用的缝线与随机放置在颈阔肌中的缝线在美学效果上没有统计学差异。在我们对107例患者的研究中，主要使用斜向垂直向量的SMAS提升术似乎比主要使用斜向水平向量的效果更好。对于颈部，我们发现随机放置的颈阔肌折叠缝线与放置在肌肉特定区域的缝线之间没有统计学差异。
