Background: Different skin excision shapes may result in different aesthetic outcomes after upper blepharoplasty. Methods: Two skin-only excision shapes were evaluated objectively and subjectively in 28 matched patients with laterally extended skin excision (group A) or traditional elliptical skin excision (group B). The pretarsal show, lateral eyebrow height, amount of scarring (evaluated with the Patient and Observer Scar Assessment Scale), and patient-reported aesthetic results (evaluated using FACE-Q) were scored and compared at 6 and 12 months postoperatively. Results: In both groups, pretarsal show improved significantly after blepharoplasty. The homogeneity of pretarsal show improved significantly in the lateral extension group (group A) together with slightly more pretarsal show (0.5 to 0.8 mm at central pupil region) at 6 and 12 months of follow-up compared with group B (P = 0.004). A trend was observed in the exocanthion 45-degree measurement, in which group A had 0.6 mm greater pretarsal show 6 months postoperatively. Homogeneity of the pretarsal show had improved significantly in group A, but not in group B, at 12 months after blepharoplasty. No other significant differences were observed between the groups regarding pretarsal show measurements or FACE-Q scores. Both groups showed descent of the lateral eyebrow, but this was only significant in group B. Group B showed 1.4 to 2.0 mm more descent compared with group A. Scarring and adverse effects scores were low in both groups and did not differ. Conclusion: Laterally extended skin excision and traditional elliptical skin excision both result in positive aesthetic results, but the laterally extended skin excision technique is accompanied by a slightly more favorable outcome.
