Will crystalline cortisone injections make a successful rhinoplasty or future revision hard to achieve?

Hi, last friday I had my official consultation for my upcoming thick-skin rhinoplasty. In the treatment plan it was said that due to the thickness of my dermal layer, to achieve a visible result, crystalline cortisone needs to be injected 12 weeks before the operation and then again after. I read that after crystalline cortisone injctions, the nose becomes impossible to operate on, which my surgon refutes. But I need a second opinion. Will I be unable to revision the rhinoplasty after?
