2 weeks after upper-blepharoplasty incisions haven't healed enough to remove the stitches. Why? Could body reject thread?(Photo)

This is very unusual and I'm sorry that you have had a difficult recovery after blepharoplasty.  For many patients, a small wound dehiscence will close normally with the natural action of blinking bringing the incision together.  You may be sleeping on your face or rubbing the lids at night, causing them to open.  In your case I would re-suture the incision, place steri-strips over it, and have you wear a plastic shield at bedtime.  Good luck!

Dehiscence is more common if deeper layers including the eye muscle orbicularis oculi has not been stitched together with absorbable sutures such as Vicryl that can last for 2-3 months.  In any case, most open wounds well-healed nicely in the beginning and do not require Suturing immediately.In fact most of the times it suturing is done on a dehiscent wound It will not take because the tissues are raw and inflamed.  It is best to let the healing complete for 2-3 weeks and revisit the wound at that time.RegardsDr. J

Some patients will have some dehiscence or opening of their scar after the sutures come out.   This is seen more commonly if sutures are removed too early after the surgery, but can also occur after 10-12 days.  When this happens, I do not re-suture.  I let the wound heal on its own which it will within about 1-2 weeks.  In almost all cases the scar looks good and no revision is needed.  In your case:  get the sutures out and let it heal.
