Revision rhinoplasty timing
Thank you for the question and your photos. It is very early to make decisions about revision. Typically the nose will take months to settle completely. It is recommended to wait a minimum of 6 months before making the decision for a revision -- and most surgeons prefer 12 months. Until then, I strongly encourage you to work with your surgeon. Massage, gentle steroid injections, etc. can be very helpful.
Determining need for revision rhinoplasty
Hello! At 4 weeks post-op, you will still certainly have expected post-surgical swelling and it is too early to determine if you will ultimately need a revision. It is not uncommon to have asymmetric swelling at this point as well, which can often make the nose look asymmetric or crooked. It will typically take up to 12 months for all of the swelling to resolve. Be sure to discuss your concerns with your surgeon who can follow your course and discuss options to help with the healing process. Good luck!
