3rd Rhinoplasty for Open-roof Deformity

This was my second rhinoplasty procedure, a revision as its called. Im very pleased witht the results, but still wouldnt mind a slight alteration. I would recommend rhinoplasty for those who are consciuous of their nose.

I've recently had a revision rhinoplasty, 2 months ago. im pleased with the results, except i have a slight open-roof deformity. Would it be difficult to correct this, considering it would be my 3rd rhinoplasty? Only the nasal bones need asjusting, so would this make it easier considering the soft tissue structures dont need to be touched? Also how long would i have to wait before i could correct it, seeing as though only the nasal bones need altering?
