Is there a way to alter the shape of the nose without surgery?

Yes: There are newer methods using injectables, known as fillers, to inject around the nose to change the shape. However, these are only temporary and do not take awake but rather add to change the shape of the nose. So will make your nose bigger. Most common used filler is hyaluronic acid, which is something our bodies make as well. Best is to discuss with a plastic surgeon.
