13 days after upper eyelid surgery, incision is still open about a 1/4" section. Any suggestion? (photos)

This does occur and is not rare. This is likely to heal very nicely. Notify your surgeon immediately and send them a photo. If a suture "pops" immediately after surgery I will typically replace it. However, if an incision opens after suture removal as your has you typically only need to keep the wound clean and moist. It will close on its own and often look the same as the side that did not open. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Some separation of the incision has happened in the area demonstrated by you in the photographs. At this point, supportive measures to maximize healing is the best approach. If revision of the incision scar will be necessary, that is best delayed for a minimum of six months. Chances for that to be necessary are still relatively low. 

However it is actually common.  The eyelid will heal remarkably well despite this dehiscence.  This only very rarely need to be repaired.  The best course is to closely follow the eyelid and often the edges of the wound come together beautifully and without the need for intervention.

There does seem to be some separation of the wound.  At this point there really isnt anything to do except let the incision heal.  I would keep in touch with your surgeon and let him or her know what is going on.  The lids generally heal very well.  So this should not be an issue when you are all healed.

Hi Rowley, thank you for your question.  Your incision seems to have opened which of course is not ideal.  The good news is that the eyelids generally heal very well.  There is nothing to do in the acute setting other than keep in contact with your surgeon, stop pulling on the eyelid (tension is the enemy to good wound healing), and keep the wound moist with ointment until the incision reepithelializes.  If the scar is unacceptable, it can typically be revised between 6 months and a year later.
