Good afternoon. After injury or surgery to the nose, it can become REALLY swollen, and this swelling can take a LONG TIME to resolve (up to 1-2 years to fully resolve). Without having personally been in the operating room during your surgery, it is hard to say exactly what is going on in your case to cause the asymmetric swelling you're describing. What you're experiencing could be the result of any graft(s) used, the technique of the osteotomies (if done), scarring, swelling, a resorbing clot, your nasal anatomy, or a combination of the above. I would recommend that you continue to observe things for now, as any revision surgeries, if necessary, typically are not done until at least 1 year after the prior nasal surgery to allow for the inflammation and swelling to resolve. I constantly remind all my rhinoplasty patients how important it is to be patient after rhinoplasty surgery as it can take months to even years to see what the final nose will look like. Hope this helps!Best, Dr. Donald Groves Plastic Surgeon
