Abstract:Objective To explore the effects of sub-brow incision lifting (SBIL) combined with double eyelid surgery on the improvement of upper eyelid skin laxity and orbital morphology, as well as the incidence of complications.Methods A total of 100 patients with upper eyelid skin laxity who were admitted to Sanya Traditional Chinese Medicine Hospital and Luoyang Xigong Laiermei Medical Beauty Clinic in Henan Province from March 2022 to March 2024 were selected for this study. The patients were divided into two groups according to the surgical method: the SBIL group (n = 48) received SBIL treatment, and the combined group (n = 52) received SBIL combined with double eyelid surgery. The outcomes compared between the two groups included orbital morphology indicators, lemperle scores, visual analogue scale (VAS) scores, satisfaction levels, and incidence of complications.Results The postoperative marginal reflex distance (MRD), medial canthal margin to fold distance (MCMFD), mid-pupillary margin to fold distance (MPMFD), and lateral canthal margin to fold distance (LCMFD) in the combined group were all significantly higher than those in the SBIL group (P < 0.05). The pre-to-postoperative changes in MRD, MCMFD, MPMFD, and LCMFD before and after treatment were also significantly greater in the combined group compared to the SBIL group (P < 0.05). At 1 and 2 months postoperatively, the lemperle scores in the combined group were significantly lower than those in the SBIL group (P < 0.05). Postoperative patient-rated and physician-rated VAS scores were both significantly higher in the combined group than in the SBIL group (P < 0.05), and the changes in patient-rated and physician-rated VAS scores from before to after treatment were also significantly greater in the combined group (P < 0.05). The overall satisfaction in the combined group was higher than in the SBIL group (P < 0.05). The incidence of complications between the combined group and the SBIL group showed no statistically significant difference (P > 0.05).Conclusion SBIL combined with double eyelid surgery has a significant effect on improving orbital morphology, with a comparable safety profile in terms of complications.
