Thank you for your question. Based on the pictures which you posted, I do see this bump on the left hand side. I agree with your surgeon in placing steroid injection to help this settle. Even at 8 months post-operatively, you can still have enough residual swelling to cause a bump/hump such as this one. I would wait a full year before considering your final result.
Be sure to discuss your concerns with your surgeon. I hope that this helps!
Large hard lump on the inside of nose on one side 8 months after Rhinoplasty. What should I do? (
Best to seek in person second opinions. But you have 2 options: Re operation or try non surgical rhinoplasty with HA filler injections.
