Is 11 days too long to wait for suture removal on the upper and lower eyelid surgery?

Your RealSelf team of expert plastic surgeons all agree each surgeon has his or her own protocol for suture removal.  That being said, if you have a choice, I would recommend you have them removed earlier.  In my practice, all eyelid sutures are out in 3 days.  It has been my experience, due to the rapid healing in eyelid tissue, epithelized tunnels are created when sutures are left in too long.  These tunnels must be surgically removed and eye makeup and other debris can fill these tunnels appearing like microscopic blackheads. 

Four to 6 days is more common.  However, if your surgeon used a laser to make your blepharoplasty incision, the sutures need to be left in place for a longer period of time.  Generally this time frame is at least 10 days but longer may be necessary.  The reason for this is that the laser thermally injures the skin adjacent to the wound.  The laser injured skin does not knit together as fast as scalpel cut skin.  This is the principle reason that I do not recommend laser surgery.  People assume that anything done with a laser is great but it is not true.  This thermal skin injury means that the sutures must be left in place much longer than is ideal and this can increase the prominence of the scars from eyelid surgery.  On the other hand, if a laser was not used to make the incision, then your surgeon really has no excuse.  That does not mean that you will be harmed by this but it is better to get the sutures out at the earliest feasible date.  Too early and the wound will separate and that is not good either.

Most of the non-dissolvable sutures that are used in a blepharoplasty are very non-inflammatory.  So if they stay in for 11 days you should have no problem.  Most surgeons try to take out the sutures once the wound is healed enough that it will stay closed after removal. If the surgery was done with a CO2 laser, the sutures are usually kept in an extra day or two.  Or if you have a lot of edema, your surgeon may want to keep them in a little longer than usual.  I think that  most surgeons remove the sutures anywhere from 6-10 days post-op.   

in my practice are removed between 3 and 5 days, primarily to avoid the development of small whitehead (milia) or scars from the sutures themselves.  But its done at the risk of the wound separating but it has never been a problem for me.

Every surgeon has a different operative technique and protocol for when they prefer to remove sutures after eyelid surgery.  Typically sutures can usually be removed between 5-7 days after surgery.  If the sutures are removed too early, the healing incision is weak and can easily open up.  While 11 days is on the longer side for for suture removal, eyelid skin is very thin and incisions typically heal very well in most patients.
