Abstract: Objective To analyze the clinical effect of internal fixation of posterior orbital septum-levator muscle complex and orbicularis oculi in double eyelid surgery.Methods A total of 100 patients who received double blepharoplasty in the Third Affiliated Hospital of Chongqing Medical University from April 2020 to October 2021.They were randomly divided into experimental group(n=50) and control group(n=50) according to difffferent treatment methods.Surgery was performed by the same surgeon with two different surgical methods,the experimental group was treated with modified double eyelid surgery,and the control group was treated with traditional surgery.And the degree of postoperative swelling,eyelid scar,eye aesthetics and complications of the two surgical methods were analyzed and compared.Results The swelling score was 5.42±0.76 in the experimental group and 6.10±0.93 in the control group on the third day after operation.The swelling score was 3.40±0.75 in the experimental group and 4.00±0.99 in the control group one week after operation.The swelling score was 1.72±0.64 in the experimental group and 2.08±0.78 in the control group one month after operation.The differences were statistically significant(P<0.05).The scar score was 2.58±0.70 in the experimental group and 3.20±0.67 in the control group one month after operation.The scar score was 1.14±0.40 in the experimental group and 1.50±0.58 in the control group 6 months after operation,with statistical significance(P<0.05).Six months after operation,the double eyelid aesthetics score and self-satisfaction score of the experimental group respectively were 4.00±0.45,4.00±0.49.The results of the control group were 3.84±0.42,3.72±0.57,the differences were statistically significant(P<0.05).The incidence of complications such as the “stripped” or “stepped” appearance was 2%，lower than that in the control group 14%,and the difference was statistically significant(P<0.05).Symptoms of the two patients with mild ptosis was improved after surgery,and the effect was satisfactory.
