The definitive treatment for your nose which is severely deficient in both nasal tip projection as well as nasal dorsum height is an open rhinoplasty with rib graft.
The good news is that we can now use an organ donated rib graft for this purpose which allows you to avoid having to use yours.
Please note that since your deficiency is so severe, I would avoid using a filler as although it will make it slightly better, you are going to then complicate your surgery as it will create scar tissue that will make estimating your graft size more difficult for the surgeon.
