Application of vascular grafting technique in facial and neck tissue expansion

Release date: 2007-12-04

The application of vascular grafting technique in facial and neck tissue expansion combined with conventional skin soft tissue expansion technology can transform the traditional expanded flap into an island flap that can be transferred with pedicle, which improves the expansion of the flap. Flexibility and flap utilization. Vascular transplantation is a commonly used method when blood vessels are defective and cannot be directly sutured. The transplanted blood vessels can be selected from autologous arteries, veins, or allogeneic arteries, veins, or artificial blood vessels. However, in microvascular surgery, autologous and vein grafts are still the most commonly used. The Chinese Journal of Cosmetic and Plastic Surgery published a study in the third issue of March. The researchers performed the operation in two phases: a stage I operation, with a superficial arteriovenous pedicle, picking up the superficial temporal fascial flap, and at the same time, peeling off the face and neck. Form an appropriate size of the tissue cavity, transfer the superficial temporal fascia flap into the tissue cavity, properly fix it, place the skin dilator under the fascial flap; in the second stage operation, after the expansion is completed, remove the dilator to make it shallow The arteries and veins are pedicled, and the traditional facial and neck expansion flaps are transformed into island flaps that can be transferred with pedicles for the repair of facial tissue defects. The vascular graft flap prefabrication technique is applied to conventional facial and neck tissue expansion, thereby improving the flexibility and utilization of the expanded flap transfer.
Researchers at the Chinese Academy of Medical Sciences and Peking Union Medical College Plastic Surgery Hospital Liu Yuanbo and other researchers showed that 11 clinical applications were used for the repair of facial wounds after facial black sputum, hemangioma and facial scar removal. The fascia of the superficial fascia island flap is 6.5-10.0cm, the area of ​​the fascial flap is 5.0cm×5.0cm-6.0cm×8.0cm, and the area of ​​the island flap of the face and neck is 6.0cm×8.0cm-7.0cm. × 17.0 cm. All the flaps survived after operation, 7 cases were directly sutured in the valve area, and 4 cases were repaired by another skin graft. Therefore, it can be seen that the combination of vascular grafting technology and conventional skin soft tissue expansion technology can transform the traditional expanded flap into an island flap that can be transferred with pedicle, which improves the flexibility and flap utilization of the expanded flap.
