This is a great question that will stimulate some controversial answers. As surgeons, and some non-surgeons, find out what the risks and limitations of fillers are we still have to advise our patients of what has worked best historically. The changes you seek can be done efficiently and permanently with fairly simple surgical procedures. These are time tested and safe. The use of fillers is not based on long term results, and there have been some significant complications, particularly in the nose. Most FDA approved fillers can be used "off-label" if a doctor decides it is in the patient's best interest. There are no FDA approved uses for fillers in the nose or chin. The other issue is cost. Fillers will last at most about one year, then you must redo the procedure or lose the effect. This can cost many thousands of dollars over a few years. The surgical cost is more up front, and there is a recovery period, but you will spend less over time. Make sure you seek advice from doctors who are able to perform both fillers and nasal/chin surgery. Many non-surgeons will only recommend the fillers, which may not be in your best interest.
