is there a limit to how much a nasal hump can be removed because I have a nasal hump and the hump has a higher angle than most humps
The limit is to achieve harmony of the nasal proportions to achieve an aesthetic result
Visit a local plastic surgeon and you will have all your answers.
Doesn't matter. Go to any qualified aesthetic surgeon. He/she will explain. As explained by Dr. Samir Shureih, it is the proportion and balance that matters in ultimate result.
Don't worry specialist plastic surgeon can do nose reconstruction for you instead of only hump reduction.
