RESUMO
BACKGROUND: For a long time, to achieve the natural shape of double-eyelid crease, multiple techniques of double-eyelid plastic surgery have been developed. We describe the trapezoid orbital septum membrane flap in blepharoplasty to achieve a dynamic double-eyelid crease and avoid a depressed static scar. METHODS: The authors developed a trapezoid orbital septum membrane flap in double-eyelid blepharoplasty. The flap base is fixed on the pretarsal plate with the distal end of the flap positioned between the superior and inferior edges of the incision. Layer-by-layer contraposition suturing is then performed. RESULTS: One hundred ninety-one cases of double-eyelid blepharoplasty were performed by a senior surgeon using the trapezoid orbital septum flap method. Patients were followed for 6 to 17 months. Twelve cases were revised secondarily. Patients were satisfied with the palpebral folds, which showed a dynamic crease followed with movements of the eyelids. CONCLUSIONS: The authors introduce a trapezoid orbital septum flap in upper eyelid blepharoplasty. The flap relies on the elasticity of the orbital septum flap as the levator aponeurosis extension segment to produce a natural crease without a depressed static scar.
