Removal of contour threads is tricky. Their design locks the suture into the tissue with it porcupine quill shape. Many times there is tissue ingrowth. The best opportunity to remove these threads is through a facelift incision. The threads can be visualized and then removed if desired. Once these threads are removed the descended tissues of the face can be resuspended in a more logical manner.
I do not recommend permanent sutures to suspend the face since a permanent structure can lead to a host of problems including infection, reaction, granuloma, etc. If your face is relying on a suture to hold it up at 1 month, your facelift is destined to fail. The only permanent suture in the body is scar, a.k.a. your body healing the tissues in a more rejuvenated fashion.
