Background : The position of the eyebrows is critical when planning blepharoptosis surgery. However, insufficient scholarly attention has been paid to the details of postoperative eyebrow height changes at each anatomical landmark. This study investigated the effect of blepharoptosis surgery on brow height and evaluated the change in brow position.
Methods : After a retrospective review of 247 patients, this study analyzed 53 patients (106 eyelids) who underwent levator and Muller’s complex advancement between March 2010 and January 2022. Brow heights were measured from the distance between the upper brow margin of each landmark and horizontal line of pupillary center on a digital photograph.
Results : The mean change of eyebrow lowering was 1.54 mm (P<0.001) at the medial canthus, 1.29 mm (P<0.001) at the medial limbus, 1.44 mm (P<0.001) at the center of the pupil, 1.40 mm (P<0.001) at the lateral limbus, 1.15 mm (P=0.001) at the lateral canthus, and 0.75 mm (P=0.021) at the lateral eyebrow end. The brow change was most prominent at medial canthus and least prominent at the lateral brow end. The preoperative brow position was only statistically significant factor predicting brow height descent after surgery according to multiple linear regression analysis (R2=0.305, B=?0.375, P<0.001).
Conclusions : The eyebrows lowered in most patients after blepharoptosis surgery. The preoperative brow position is the most important factor in predicting the change in brow height after blepharoptosis surgery.
