Ectropion after upper eyelid surgery generally corrects itself
Most of the issues related with upper eye lid irregularities corrects by itself after a period of about three months. I would be patient and follow up with my surgeon.
Upper lid Ectropion: Very Rare
As Dr. Blinski said, it is far too early to evaluate your results. Upper lid ectropion is something much more common in overweight sleep apnea patients; I have personally never seen it after surgery. Give it more time and more than likely the asymmetry will resolve.
Revision surgery for ectropion should be made after eye has healed
It is very rare to have an ectropion of the upper eyelids after an upper lid blepharoplasty. Since it has only been three weeks after your surgery, wait at least three to four months to allow swelling to subside before embarking on any further eyelid or blepharoplasty surgery. Once it is healed there are possibilities to reduce or remove asymmetries or ectropion.
Sometimes early post-op, patients develop ectropion. This may be from weakness, over resection of lower eyelid skin, poor fixation of a canthopexy or all of the above. Sometimes simple massage or taping can help improve the minor symptoms.
Ectropion after double eyelid surgery
Ectropion after Double Eyelid Surgery is a rare problem. When it occurs it can usually be corrected with time and massage. Sometimes sutures may need to be loosened. Be patient and hopefully this will correct itself.
Delay any blepharoplasty revision
It sounds like the asymmetry in the upper eyelid is something that will improve with time and tissue relaxation. If your eye ball or cornea is adequately protected I would ask you to wait at least three months before doing any other procedure.
Try to be patient and do some light massage and see how everything heals as the tissue softens with time. The upper eyelid is more forgiving than the lower eye lid and you may find that no revision is necessary.
Ectropion of the upper eyelid is unusual but usually self corrects
Sorry to read that you are having difficulty after your surgery. Fortunately, in contrast to lower eyelid ectropion this abnormality in the upper eyelid often will self correct over a few months.
If the self correction does not occur enhancement procedures are available
Good luck and be patient !
Wait at least 3 months for evaluation of Blepharoplasty results
First, your complaint is WAY too early, you need to wait at least 3 months. Second upper lid ectropion is very rare occurrence, I doubt you really have that. Third, GO talk to the operating surgeon, now! Best of Luck.
