What does releasing of ligaments mean in a facelift? How many would be released and where on the face, how are they reattached?

There are many techniques available for effective facelifting.  Most , if not all, involve cutting the retaining ligaments to allow better redrapage of the skin.  

In many cases, retaining ligaments need to be released to improve the overall results.  Each case is different so you will need to discuss with your Board Certified Plastic Surgeon.
