Objective To explore the clinical effect of soft-suspension orbicularis oculi external fascia suspension technique (hereinafter referred to as "modified soft-suspension technique") in double eyelid surgery. Methods A total of 40 patients undergoing double eyelid surgery who were treated in the Outpatient Department of Plastic Surgery of Longgang Central Hospital of Shenzhen from January to December 2024 were selected as the research subjects, and they were divided into the control group and the study group by the random number table method, with 20 patients in each group. The control group was treated with traditional incision method, and the study group was treated with modified soft-suspension technique. The recovery time, aesthetic effect, patient satisfaction and complication rate were compared between the two groups. Results The postoperative recovery time of the study group was shorter than that of the control group (P <0.05). The aesthetic effect scores of the study group at 1, 3 and 6 months after operation were higher than those of the control group (P <0.05). The patient satisfaction scores of the study group at 1, 3 and 6 months after operation were higher than those of the control group (P <0.05). The incidence of complications in the study group was 5.00%, which was lower than 30.00% in the control group (P <0.05). Conclusion The application of modified soft-suspension technique in double eyelid surgery can effectively shorten the postoperative recovery time, improve the aesthetic effect and patient satisfaction, and reduce the incidence of complications , which is worthy of clinical application.
