Skin incision is considered to be placed at 90° in reference to the skin to get perfect wound edge adaptation. The incision on hair-bearing tissues, as the scalp, is considered to be bevelled at 45° to promote hair growth through the scar. There is no consensus about the preferred incision angle on the brow. The aim of this article was to demonstrate the feasibility of the “flat incision technique” for brow repositioning, where brow deformation results after forehead reconstruction. A wound-healing model for the bevelled incision is presented.Methods:
Brow incisions are bevelled with an angle of 20°. The lower incision is placed inside the brow so that the upper 2 rows of hair are included; the dermis is completely transected and dissection is continued into the subdermal plane. The procedure is presented in a patient who underwent resection of the forehead due to melanoma.Results:
The bevelled incision increases the surface area of dermal layer by a factor of 2 compared with the standard vertical skin incision at 90°. Loss of the dermal tissue integrity and continuity due to trauma hinders the recovery of cell migration and function, resulting in a more prominent scar formation. It appears reasonable that with the increased surface area of the dermal layers in the wound edges, the scar quality improves. The case study demonstrates the feasibility of the procedure.Conclusion:
The bevelled 20° incision for brow repositioning and reshaping showed to be a viable and predictable procedure.
