Nose shaping with fillers and botox, namely Liquid Rhinoplasty as I call it, has three main target audiences:
Nose has a thin and fragile vascular network in a very limited space. If the many different variations of the arteries in particular is considered, one should have a good command on anatomy, and practice with the utmost attention and precaution on procedures at this area.
The advantages of being a plastic surgeon who has performed hundreds of rhinoplasties show up at this very point.
As in all other facial filler procedures the problematic areas should be clearly defined for the nose as well, and the right filler should be injected at the right amount and to the right layer. If necessary, the procedures should be divided into sessions.
