Hello and thank you for your question. Unfortunately, you actually have a VERY difficult problem to fix. Your tip/nostril asymmetry and crooked nose after a prior rhinoplasty is due to either 1) an issue with the initial surgery, or 2) due to contractile scarring forces, which can unfortunately distort results over time as the underlying tissues heal and shrink, altering the shape of the nose. There are certain maneuvers which can be performed during rhinoplasty surgery to prevent such retraction and distortion- I actually perform these preventative maneuvers in all my rhinoplasty surgeries for this very reason. Because filler is not strong enough to overpower the extensive scar tissue present, you would need a revision rhinoplasty to properly correct your issue and to solidly reinforce the entire underlying framework to assure you get the BEST long term results. Anyone who tells you otherwise is doing you a HUGE disservice! Also, nasal filler carries can potentially make you go BLIND! Revision rhinoplasty is truly a surgery of millimeters- they are the most technically challenging procedures in all of plastic surgery! Because your nose is the DEFINING feature of your face- I would only recommend seeing a surgeon who specializes in revision rhinoplasty procedures, and who has significant training and experience performing these surgeries. I actually trained under one of the world leading revision rhinoplasty experts (who performs 1,000+ nosejobs annually). I recommend for you to setup a formal consultation with me (or another plastic surgeon who is extremely comfortable with revision rhinoplasties) to thoroughly discuss your surgical goals, undergo a formal examination, evaluate your options, and develop a personalized plan just for you. I hope this helps! Dr. Donald Groves Aesthetic Plastic Surgeon
