Alar retraction? 5 weeks post open rhinoplasty surgery. what are my options? how soon i can fix it? (photo)

Too early yet to do anything about the retracted ala.  However, in cases such as yours, I have had success with the placement of an alar rim graft, a procedure that can be done as soon as 3 months post-op, with the placement of a small strip of ear cartilage right into the area of retraction.  This procedure is done under local anesthesia most commonly.

You do have a slight bit more retraction of the left ala compared to the right, but bear in mind you may still have edema of the tip of the nose.  When this swelling goes down, you may have less obvious retraction or none at all.  In any event re-operation is best delayed for at least 6 months.

It would be helpful to see your preoperative photos for comparison.  The alar retraction is visible in the frontal view.  Overall, your nose looks very nice and there is mild tip edema as expected at this point in your recovery.  Generally, most surgeons recommend waiting 6 months to one year to allow the swelling to subside and complete healing to occur before any revision is considered.However, another option would be to inject an HA filler in the retracted area once the skin is soft enough to allow some expansion with the injection.  Hyaluronic acid fillers (i.e., Juvederm, Restylane, etc) can be quite effective for minor postoperative rhinoplasty irregularities.  The longevity in the nose is generally good and can be repeated in the future if needed.
