<p>Quantitative assessments of changes in skin laxity before and after subbrow blepharoplasty have been performed; however, the effects of double eyelid clarification accompanying outward rotation of the eyelashes, have not been reported. This study examined the method for revealing natural double eyelids in subbrow blepharoplasty. We included 30 patients (60 eyelids) who underwent bilateral subbrow blepharoplasty. During surgery, we measured the distance from the edge of the eyelid to the lower incision below the eyebrow at the lateral canthus and medial cornea after removing excess skin to reveal natural double eyelids. All patients exhibited double eyelids and were observed for at least 6 months postoperatively. The width from the eyelid margin to the lower incision line below the eyebrow, which is necessary for the exposure of double eyelids, was 21.72 ± 0.98&#xa0;mm on the lateral canthus and 22.60 ± 1.32&#xa0;mm on the medial cornea. In 36 patients who were followed up for 1 year, the distance from the pupil center to the upper eyelid edge showed significant improvement at all postoperative time points, compared to preoperative levels. Subbrow blepharoplasty reveals a natural eyelid crease with appropriate skin removal, aiding in an eyelid elevation effect without eyelash ptosis.</p>
