Quantitative and Aesthetic Analysis of Changes in Eyebrow Position After Subbrow Blepharoplasty.

[BACKGROUND] Narrowing of the distance between the eyes and eyebrows is commonly observed after subbrow blepharoplasty. The purpose of this study was to quantify the changes in brow-lid distance after subbrow blepharoplasty in Asian women.

[METHODS] We observed and standardized the pre- and postoperative photographs of 63 patients who underwent subbrow blepharoplasty from January 2020 to October 2022. We measured the distances from the medial and lateral eyebrow to the lower lid margin on the right side of the face and then analyzed the changes in postoperative brow-lid distance using the standard iris diameter for Asian women of 11.5 mm as a reference.

[RESULTS] Photographs of 63 patients were included in the study. All 63 patients were females. The average postoperative distance of the lateral eyebrow to the lower lid margin was 30.08 ± 2.74 mm, a significant decrease in comparison to the preoperative distance (31.84 ± 2.65 mm) (P < 0.001). The mean postoperative distance of the medial eyebrow to the lower lid margin was 25.84 ± 2.87 mm, compared with that of the preoperative distance (27.59 ± 2.94 mm), which was a significant decrease (P<0.001). All 63 patients (100%) had a decrease in the lateral eyebrow distance, while 59 (93.65%) had a decreased medial eyebrow distance.

[CONCLUSIONS] There was a statistically significant change in brow position, consistent with our observations. Subbrow blepharoplasty can cause a decrease in the distance between the eyebrows and eyes.
