Couple of thoughts.Wait until 9 months before considering a revision. Your tip is swollen which can effect the appearance. That being said, your nostrils are assymetric. If they stay that way after the swelling resolves you could discuss a revision rhinoplasty with cartilage grafting to improve the tip shape. Best
As others have said, I would wait a full 12 months from your rhinoplasty before considering any revision. That being said you must first determine if you had any asymmetry before your surgery. If you did not and there was an alar base reduction (nostril/base) and they are not equal now, this should be able to be fixed. Nostril asymmetry that is inherent in an individual, particularly in the area near the soft triangle (front/top of nostril) is very difficult to correct. There is a good chance this could be from tip swelling so I would sit tight and see if things do not get better on their own.
