There are many different techniques for fixation in the endoscopic brow lift. I have used the "bone tunneling" technique, the "screw" technique, the "no fixation" technique and the Endotine technique. They all basically do the same thing, keep the skin elevated long enough to allow it to stick down to the bone. The older Endotines stuck around for up to 2 years which made them annoying for the patients. The newer Endotines dissolve in about 2-3 months and are therefore much less problematic. And, they are very easy to use. Is there anything wrong with the other techniques? No, they're all fine. What matters is how comfortable your surgeon is using the technique he has chosen.
In addition the number of of transverse cuts in the periosteum (the layer of tissue just above the bone) will determine how well the tissue can be elevated.
