Are these my internal sutures snapping?

Hello, and sorry to hear about the issue you experienced following surgery. After 3.5 weeks, you are still going to have significant stiffness from your surgery. In general, the side effects of a facelift can include the following:

1) Swelling
2) Redness
3) Bruising
4) Stiffness
5) Tenderness

The snapping you felt was likely a result of scar tissue, but without knowing the details of your surgery it is difficult to pinpoint the problem and say for sure if they were your internal sutures. This should not be of great concern, but I would recommend speaking with your surgeon. He/she knows the extent of your surgery and will be able to advise you. I hope this helps, and best of luck!

    This snapping sound could have been suture or it could have been scar band.  If your contours have not changed, then you are likely fine.  Followup with your plastic surgeon for confirmation.

the snapping my have been sutures breaking..   i wouldnt do anything now but let it all heal and see if you look fine in 3-6 months
