ABSTRACT

Objective:To investigate the clinical application and effect of orbicularis oculi muscle shaping in lower blepharoplasty.Methods:A retrospective analysis was performed on the clinical data of 32 cases of flabby blepharoplasty patients admitted to the Orthopedic Surgery Clinic of Sichuan people＇s Hospital from October 2018 to September 2019. At the same time of transcutaneous blepharoplasty, 32 patients were treated with orbicularis oculi muscle shaping to remove the relaxed orbicularis oculi muscle, to reconstruct the annular strength and shape of the orbicularis oculi muscle, to strengthen the supporting structure of the lower eyelid, to reset the relationship between the external canthus orbicularis muscle and the skin, and then to reconstruct the soft tissue filling degree of the lower eyelid margin. The safety, efficacy and stability of the operation were evaluated by Barton grading, postoperative complications and scoring before and after operation and satisfactory analysis based on patients＇ satisfaction scale after operation.Results:All the patients were free of postoperative infection and healed at stage I. There were 2 cases of ecchymosis, 3 cases of ocular foreign body sensation, and no cases of infection, lower eyelid retraction, lower eyelid ectropion, or retrobulbous hematoma. The mean Barton score of all patients before surgery was 1.88±0.49, and the mean Barton score after surgery was 0.53±0.51. The t-test showed that the difference was statistically significant ( t=15.75, P<0.05), and the postoperative lacrimal groove deformity was improved. According to the score of satisfaction scale, 7 people were basically satisfied (21.88%) and 25 people were very satisfied (78.12%). Conclusions:Forming in the orbicularis oculi muscle relaxation eyelid bag type of prosthesis, in addition to the part of the orbicularis oculi muscle relaxation, deformation, and widely shed canthus outside skin and orbicularis connection, make the next eyelid edge to reproduce the full shape, obviously the bulging under the eyelid relaxation, the shape of the degree of repair, lateral canthus wrinkles tail department have also improven, restoring the full eyelid platform. The operation has strong pertinence, simple procedures, less complications and better long-term effect.
