Endoscopic vs Irregular Trichophytic Forehead Lift? Advantage of an endoscopic forehead lift is two incisions behind the hairline, lifting the brows. The disadvantage of this procedure is it does not lift the brows as well and provide access to removing any supraorbital bone. The Irregular Trichophytic Forehead Lift that I invented.gives thebest elevation of The brows and provides access to the supra orbital bone and the brow corrugators. This is based on more than 5000 of these that I have done. If not properly done, this would leave an objectionable scar-Properly done no scar will be seen since hair grows through the incision, which is what differentiates this from the pre-trial Incision which is in front of the hairline.
