摘要
目的 解剖学观察埋没导引缝合颧脂肪垫提升术适宜的悬吊部位、悬吊层次、悬吊线间距以及悬吊线锚定点。方法对4具（8侧）新鲜尸头模拟埋没导引缝合颧脂肪垫提升术，观察术中、术后效果，记录数据并照相。结果埋没导引缝合颧脂肪垫提升术的悬吊部位，应该在颧脂肪垫外侧部，适宜的悬吊点位于鼻翼上缘水平线与外眦垂直线的交点（Z点）；悬吊层次为皮下脂肪层和颧脂肪垫；悬吊线间距在1．5cm左右为佳；悬吊线锚定点在颞区，其位置是通过Z点在鼻唇沟的垂线和耳垂线的交点，锚定层次为颞深筋膜。结论埋没导引缝合颧脂肪垫提升术是一种简单有效的面中部提升术，但仍需要循证医学的疗效验证。
Objective To observe optimal suspension position, suspension layer, the width of suspension sutures and the position and layer of the point that the suspension suture anchored of the elevation of malar fat pad with guided suture under tissue based on anatomical research. Methods Malar fat pads were lifted with guided suture in 4 fresh-frozen cadaver heads, intraoperative and postoperative data were recorded and photos were taken. Results The adapted suspension position of malar fat pad lifting with guided suture is the outside lateral of malar fat pad and the suspension point is at the crossing of a vertical line down from the lateral canthus and a horizontal line from the superior margin of the ala of the nose （Z point）. The suspension layer is the subcutaneous layers and the malar fat pad. The optimal width of suspension sutures is about 1.5 centimeters. The position of the point that the suspension suture anchored is at the crossing of a line vertical with ear and a line that pass the crossing of the line paralleled to the superior margin of the ala of the nose and the line vertical with the lateral canthus vertical with the nasolabial fold. The layer that the suspension suture anchored is the temporal deep fascia. Conclusion The malar fat pad lifting with guided suture under tissue is an easy technique for midface lifting with excellent effect, but evidence-based medicine is still needed for clinical efficacy.
