Although we commonly observe eyebrow drooping during and after blepharoptosis surgery, it may not occur in some cases. After levator resection was performed in 47 patients (84 eyelids) with blepharoptosis, the eyebrow heights at the medial canthus, the center of the pupil, and the lateral canthus were measured using scanned photographs obtained preoperatively and 3 months postoperatively. In the 84 eyelids, after levator resection, the eyebrow position was lowered at the medial canthus in 76 patients (90%), at the center of the pupil in 75 (89%), and at the lateral canthus in 76 (90%). The mean distance of eyebrow drooping in the 84 pupils was 2.74 mm at the medial canthus, 2.91 mm at the center of the pupil, and 2.58 mm at the lateral canthus. In addition, there was a significant difference between the extra skin excision group and the no skin excision group at the medial canthus (p = 0.027), the center of the pupil (p = 0.001), and the lateral canthus (p < 0.001) (Mann-Whitney test). Unfortunately, there was a significant difference in ages between the extra skin excision group and the no skin excision group. In conclusion, eyebrow drooping was caused after levator resection in most cases. However, it is difficult to anticipate eyebrow drooping distance before surgery.
尽管我们在进行上睑下垂手术时和手术后经常观察到眉毛下垂，但在某些情况下可能不会发生。对 47 例（84 只眼）上睑下垂患者行提上睑肌切除术，术前及术后 3 个月采用扫描照片测量内眦、瞳孔中心及外眦处的眉高。在 84 只眼中，提上睑肌切除术后，76 例（90%）患者内眦处眉位降低，75 例（89%）患者瞳孔中心处眉位降低，76 例（90%）患者外眦处眉位降低。84 只瞳孔内的眉毛下垂平均距离为内眦处 2.74mm，瞳孔中心处 2.91mm，外眦处 2.58mm。此外，在内眦（p=0.027）、瞳孔中心（p=0.001）和外眦（p<0.001）处，有皮肤切除组与无皮肤切除组间差异有统计学意义（Mann-Whitney 检验）。遗憾的是，有皮肤切除组与无皮肤切除组间的年龄差异有统计学意义。结论：大多数情况下，提上睑肌切除术后会导致眉毛下垂。然而，术前很难预测眉毛下垂的距离。
