Left over suture 4 months post-op Asian blepharoplasty (Photo)

In either case, it is better to have it removed since it serves no purpose at this point and leaving it in place can cause a small hole where the suture currently resides.

Thank you for your question and photos.  You should have the sutures removed by your surgeon sooner rather than later. I do not recommend that you remove it yourself because you may not be able to remove it in its entirety.  At this point, scar tissue should have formed and the crease should be intact even without the anchoring sutures. You would also benefit from steroid injection to the slightly hypertrophic scar that has formed on your medial eyelid. Best wishes.  

Thank you for sharing your question and photos. Those exposed sutures need to be removed. Your skin looks inflamed and should be evaluated for possible infection by your surgeon. Good luck.

Generally, any exposed sutures should be removed since bacteria can travel along the stitch into the skin, causing an infection.  While it's possible you may lose your crease it has been over 4 months since surgery which has allowed a scar to form (a good thing).  It's important to follow up with your doctor and not to remove the stitch by yourself.  Cheers

It looks like a fixation suture that is exposed. This should be removed as this can potentially cause an infection in the future. The "bump" will improve in quality over time.

It looks more like the suture to close the incision was left behind.  That sometimes happens since swelling can hide the suture knot from even the most detail oriented surgeon.  You should follow up with your surgeon and they should remove it.Even if it's an "anchoring" suture to hold the crease if it is extruding out of the skin it needs to be addressed.  The bumps will go away most likely so don't worry about that too much.Chase Lay, MDAsian eyelid surgery expert.

I would recommend removing any suture which is irritating but the supratarsal suture was probably designed to accentuate or establish  the lid crease, Your plastic surgeon will help you decide  the benefit or suture removal.Michael Eisemann M.D.Plastic SurgeonHouston,Texas
