Although upper eyelid blepharoplasty is one of the most frequently performed facial plastic surgical procedures, there is no consensus of opinion about the effect of an upper eyelid blepharoplasty on the position of the eyebrows in a general population.
This study was undertaken to determine this effect and to investigate whether preoperative compensatory rhytidosis of the forehead may cause a significantly greater postoperative lowering of the eyebrows.
An evaluation of 140 consecutive patients with complaints of visual impairment was performed, who underwent an upper eyelid blepharoplasty. The position of the eyebrows was measured pre- and postoperatively at three positions for each eye. In addition, the role of compensatory rhytidosis on eyebrow position was determined by classifying horizontal forehead lines.
The mean drop in eyebrow position for all patients ranged from 0.35% to 1.23%. In females (n = 126), there was no significant postoperative drop in eyebrow position. In males (n = 14), however, one out of six measured distances (centre of pupil, lateral iris and lateral canthus) displayed a significant lowering of the eyebrow (p = 0.005).
Our results show that the position of the eyebrow is not lowered significantly after an upper eyelid blepharoplasty performed among women with dermatochalasis and functional complaints of visual impairment. Male patients showed a slight trend of lowering of the eyebrows postoperatively. Preoperative lifting of the eyebrows by means of frontalis muscle activity did not influence the position of the eyebrows postoperatively, although forehead lines did seem to diminish significantly.
尽管上睑成形术是最常进行的面部整形手术之一，但对于一般人群中上睑成形术对上睑位置的影响，尚无共识。
本研究旨在确定这种影响，并探讨术前额部代偿性皱纹是否会导致术后眉毛明显下垂。
对 140 例因视力障碍而就诊的连续患者进行评估，这些患者均接受了上睑成形术。术前和术后在每只眼的三个位置测量眉毛位置。此外，通过分类水平额线来确定补偿性皱纹对眉毛位置的作用。
所有患者的眉毛位置平均下降范围为 0.35%至 1.23%。在女性（n=126）中，术后眉毛位置无明显下降。然而，在男性（n=14）中，有一个测量距离（瞳孔中心、虹膜外侧和外眦）显示眉毛明显下垂（p=0.005）。
我们的结果表明，在上睑皮肤松弛和有视力障碍的女性中进行上睑成形术后，眉毛位置不会明显下降。男性患者术后眉毛有轻微下垂趋势。尽管额线明显减少，但通过额肌活动抬高眉毛术前并不影响术后眉毛位置。
