Objective:To explore the surgical method and clinical effect of bionic double eyelid operation with "8" suture and anchoring.Methods:A retrospective study was conducted on the received double eyelid operation with "8" -shaped suture and anchor in the Department of Plastic Surgery People’s Hospital of Jinhua City, Zhejiang Province (Jinhua Hospital Affiliated to Wenzhou Medical University) during November 2016 to October 2020. The upper eyelid layer is dissected, the normal double eyelid structure of oriental is simulate. Using "8" -shaped suture anchorage technique, through horizontal mattress "8" -shaped suture, the orbital septum-upper eyelid levator aponeurosis complex (A) and the orbicularis oculi muscle (M) of the lower lip of the incision were relocated and healed on the tarsal plate (including pretarsal fascia) (T) the dynamic structure of the oriental double eyelid was reconstructed. In follow up, the upper eyelid flatness, the upper eyesight extent, the distance between the eye and eyebrow, the forced sensation of opening the eyes, bilateral eyes’ symmetry, the curve and the stability of the double eyelid, the eyelash curl, incisional scar and complications were recorded and evaluated.Results:A total of 103 patients, 5 males and 98 females, with a mean age of 29.5 years (17-65 years), were included. After the postoperative follow-up of 6 to 24 months, the upper eyelid was smooth, plump and moderate, the upper vision increased, the distance between the eyebrow and eyes was relatively shorter than the preoperative, the eyes openings were widened, the two sides were basically symmetrical, the double eyelid line was natural and smooth, the crease was stable, the eyelashes were slightly curled, the incision scar was not obvious. complications, such as infection and ptosis did occur.Conclusion:The "8" -shaped suture anchoring bionic double eyelid operation introduces the concept of "breaking" then "building", the upper eyelid can be dissected clearly, the reduction is accurate, the fixation is accurate, and the mechanical structure is stable. Postopertively, the shape of the upper eyelid was natural and stable.
