Abstract:
Objective:To study the effect of bridge orbicularis oculi muscle flap blepharoptosis in the treatment of post-burn scar contracture ectropion.Methods:The clinical data of patients wih post-burn cicatricial ectropion treated with bridge orbicularis oculi muscle flap from April 2006 to September 2020 of Department of Plastic Surgery, Affiliated Hangzhou First People’s Hospital, School of Medicine, Westlake University were analyzed retrospectively. For patients with severe eyelid scar contracture caused by head and face burns, after releasing the scar and resetting the eyelid margin, orbicularis oculi muscle flaps were made at the base of the upper and lower eyelid release incision, crossed the muscle flap over the eyelid adhesion point of the eye fissure, by performed bridge cross transfer, and fixed to the orbicularis oculi muscle at the base of the release incision to form eyelid adhesion. H-shaped full-thickness skin graft or medium-thickness skin graft was performed on the defect wound during the operation. Tie-over dressing fixation in the skin graft area. One year after the operation, it was confirmed that the skin graft was stable and there was no recurrence of ectropion, and then cut the adhesion. Follow-up for more than one year after the operation, foreign body sensation, conjunctival sac pusc, skin graft survival, success rate of eyelid adhesion, anti-stretching effect of muscle flap, skin retraction rate and complications were observed. The distances between eyelid margins preoperative and after incision of eyelid adhesion were measured. SPSS 25.0 software was used for data statistics, measurement data was represented by M ( Q1, Q3), and counting data was represented by cases. Results:Fourteen patients (23 eyes) were included in this study, including 11 males and 3 females, aged 41.5 (32.5, 47.0) years, and the time from burn to this treatment was 13.5 (10, 24) months. 5 cases (7 eyes) were not treated with skin grafting or blepharoptosis after burn, and 9 cases (16 eyes) were treated with blepharoptosis and/or skin transplantation. The area of skin graft during operation was 37 mm ×18 mm to 52 mm ×39 mm. Before operation, the distance between the upper and lower eyelid margins was 14 (12, 14) mm when eyes were open, and 6 (5, 9) mm when eyes were closed. After eyelid adhesion surgery, the patient had no foreign body sensation and infection, and all the skin grafts survived. The success rate of blepharoptosis was 100%, and there was no accidental rupture or elongation. The eyelid adhesions contracted synchronously when the patients closed their eyes, and the muscle flap had good anti-stretching effect. The duration of blepharoptosis was 13(12, 24) months, during which no complications or adverse reactions occurred. The average skin graft retraction rate was 9% (5%, 10%) in half a year. After incision of the orbicularis oculi muscle flap, the distance between the upper and lower eyelid margins was 9 (8, 9) mm when the eyes were open, and 0 (0, 0) mm when the eyes were closed.Conclusion:Bridge orbicularis oculi muscle flap tarsorrhaphy can provide long-term tarsorrhaphy, effectively reduce skin contracture after eyelid skin grafting, and has a stable therapeutic effect on postburn ectropion.
