Abstract
Performing a conventional Z-plasty on postburn scar tissue frequently leads to varying degrees of necrosis of the tips of the transposed flaps. In the conventional technique, the flaps are transposed first by anchoring the tips and then by performing the other sutures. In this order, the tips are subjected to a high degree of tension. Again, according to the conventional technique, perpendicular incisions are performed along the tips, which do not ensure the effective vascularisation of the tips in this context of postburn scarring tissue with loss of dermal blood flow. Two technical modifications are proposed: a different approach to the tension by first of all anchoring the base of the flaps and not by classical first suturing of the tips and the performance of oblique incisions away from the tips to ensure a maximum vascularisation of the subdermal fatty tissue. These two elements have allowed us to improve the results of our plasties.
