Hello and thank you for your question. Unfortunately, surgery is the best option to address the dorsum as well as the size and definition of the nasal tip, as in your situation. Filler might provide partial improvement, but would not fully achieve your goals, and would only be temporary in nature. The less defined appearance of the tip is due in part to the thickness of the skin and also due to the underlying anatomy present- a combination of your nasal bones and cartilage makes up the structural framework of your nose, including the support for the dorsum and the tip. 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. In addition to addressing your aesthetic 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
