Hello and thank you for your question. Honestly, surgery is the best option to address your dorsal bump and refine the size and shape of the nose, as in your situation. Filler can help partially mask the bump in some situations, but even when performed, would only be temporary in nature. Also, given you've previously had a rhinoplasty, and there is no doubt extensive scar tissue present in your nose, fillers will likely be unable to overcome the scarring, and only an open revision rhinoplasty can best address your issue. The shape of your nose is due to the underlying anatomy present- a combination of your nasal bones and cartilage makes up the structural framework of your nose. Addressing the shape of the nose (especially the nasal dorsum and nasal tip) is actually one of the most common reasons people seek out and undergo a rhinoplasty procedure. Revision surgery would provide optimal results to achieve your goals, and frankly would be the safest option, given the risk of blindness with fillers to the nose (and that's before all the scarring of surgery has altered and distorted the underlying anatomy). In addition to addressing your aesthetic nose concerns, your septal cartilage (or an off-the-shelf alternative) would be harvested (removed) and turned into multiple cartilage grafts, which would then be secured into different areas of your nose for structural support, including in the columella (middle bottom portion of your nose between your nostrils) to really reinforce the tip and prevent long term alterations/distortions to nose shape. The open approach is very effective in facilitating complex, precise maneuvers to refine the nasal shape and size to a particular aesthetic and look. Rhinoplasty is arguably the most difficult procedure to perform in all of plastic surgery. I would only recommend going to see a surgeon who feels very comfortable with both primary and revision rhinoplasty procedures, and who has significant training and experience in these types of surgeries. This is a surgery of millimeters, so if the surgeon you're going to only does 1-2 per month, you are not going to get the best result possible. Of course it is always difficult to provide tentative surgical recommendations, as there is only so much information to be gained from the photos and description provided. Dr. Donald Groves, our expert facial plastic surgeon, has extensive training and experience with complex rhinoplasty surgeries, so I’d recommend for you to come see him (or another plastic surgeon who is extremely comfortable with rhinoplasties) for a formal consultation to thoroughly discuss your surgical goals, undergo a formal examination, evaluate all your options (surgical and nonsurgical), and decide on the best procedure(s) and type of anesthesia for your specific case. I hope this helps! Dr. Emer
