Evaluation of the eyebrow position after aponeurosis advancement.

Patients often develop eyebrow drooping after blepharoplasty or ptosis repair. After aponeurosis advancement was performed in 53 patients (100 eyelids) with blepharoptosis, the eyebrow heights at the medial canthus, center of the pupil, and lateral canthus were measured using scanned photographs obtained preoperatively and 3 months postoperatively. In the 100 eyelids subjected to aponeurosis advancement, the eyebrow position was lowered at the medial canthus in 81 eyelids (81%), at the center of the pupil in 84 eyelids (84%), and at the lateral canthus in 80 eyelids (80%). The mean distance of eyebrow drooping in the 100 eyelids was 2.80 mm at the medial canthus, 2.87 mm at the center of the pupil, and 2.50 mm at the lateral canthus. The preoperative margin reflex distance (MRD) was significantly associated with the distance of eyebrow drooping at the medial canthus, the center of the pupil, and the lateral canthus in the 100 eyelids, but the postoperative MRD was not significantly associated with these parameters in the 100 eyelids. In conclusion, eyebrow drooping developed after aponeurosis advancement in most cases, and the distance of eyebrow drooping was associated with the severity of blepharoptosis.
