Onlay Dorsal Graft - Removable?

hi docs... i had my rhinoplasty 4 months ago..done by maybe the best italian specialist, my problem is that when we were planning for the operation i was very scared and asked exactly what he would do to my nose to make it larger in the middle vault where my problem was, infact when i had nasal strips i could breathe better and my nose would look better, and i didnt want to change too much my nose just add support on the sidewalls, so he said me that i'd need support on the middle vault and he would put spreader graft and a columellar strut to make the tip not lower too much especially when smiling. i was ok with that....... then when i woke up i asked how it went and he said perfect and he said he had also put an onlay dorsal graft to give more support and to make my nose look more masculine. my problem is that now i have more support on the sidewalls but also have this dorsal graft that makes my nose higher and still make the angle between dorsum and sidewalls sharp wich was why i did the rhino.....to have that angle more flat.... my question is why did he put an onlay dorsal graft as i didnt ask for higher profile neither i had saddle nose neither i wanted it narrower, actually was opposite i wanted it larger fuller..... and is this onlay dorsal graft removable and would i have to pay for it? this thing makes me mad as i didnt ask for this, i was very cleared what i wanted and in pre-op planning i asked exactly what he would do to my nose... and he never mentioned putting a graft on the dorsum
