ABSTRACT
Objective@#To explore the clinical application effect of the orbital periorbital perforator flap pedicled with zygomatic artery to repair the defect of eyelid ectropion and the defect after tumor resection.@*Methods@#(1)Perfused 10 fresh cadavers gelatin lead oxidate with one-time arteriography and CT spiral scanning, and imported DICOM data into Mimics 17.0 for rapid body mapping and three-dimensional reconstruction, and observed the source of zygomatic orbital artery and distribution rules of perforating branches. (2)From July 2012 to July 2017, 18 clinical cases were repaired by orbital periorbital perforator flap pedicled with zygomatic artery, the flap was cut with the same width as the defect width, and the length of the flap was 2 to 3 times the defect length, with an area of 0.3 cm × 1.5 cm to 2.0 cm × 3.0 cm.@*Results@#The zygomatic orbital artery originated from the superficial temporal artery, extending up to about the midpoint of the line between the anterior ear and the lateral canthus.The clinical application of the orbital periorbital flap with the perforating branch of the zygomatic orbital artery in 18 cases survived and healed well. After 1 month to 2 years of follow-up, the color, texture and shape function recovered well.@*Conclusions@#The orbital periorbital flap with the perforating branch of the zygomatic orbital artery is a good method for reconstruction of ectropion and palpebral defect due to its reliable movement and the arterial arch connected with the orbicularis suborbicularis.
ABSTRACT
Objective To explore the effect of the island flap application on repairing large scale defects on the face.Methods Based on the defect size,shape and location,preauricula narrow stem side geny-neck flap,submental island flap,angular artery flap,eyelid musculus orbicularis flap and nasolabial groove island flap were used to repair the large scale defects of the face in a one-stage operation.Results All flaps survived well without any obvious complications.35 patients were followed up for 1 to 36 months.Repaired tissues were well matched with the surrounding tissue.Resulting facial contour and appearance were good,and cosmetic results overall were satisfactory.Conclusion The application of island flaps to repair the large scale defects on the face in a one-stage operation is a better method that can achieve good contour and satisfactory cosmetic results.
