How Long Before Neck Lift Stitches Are Dissolved?

Sutures used in neck lift procedure may me permanent sutures so the dissolving issue may not apply to your question.  If your sutures dissolve the usual time frame can be 1 to 6 months or so for the most common dissolvable sutures.

I practice in West Los Angeles. Each and everyone of my patient's sign a consent that among other things tells them that they must call me for any issue after surgery and to expect that I will want to see them personally if they are having an issue. I would much rather see someone for something that turns out to be nothing than miss something important.
The issue you are having warrants being seen by your surgeon.
Regarding when the suture is likely to dissolve, this very much depends. I typically use permanent stitches to support the neck rather than dissolvable sutures. Any suture material can become a source for inflammation and need to be removed, dissolvable or not. So please don't wait to see if the stitch is going to dissolve on its own. A stitch abscess warrants the removal of the offending suture material.
Please call your surgeon and have this handled.
