Can I have nose deviation corrected by getting punched opposite way?

It takes years of training to learn how to punch someone in the nose just right in order to make these small corrections. Don't try this at home!!Seriously, don't have someone punch you in the nose. It won't work and could make matters worse. If the bones have healed out of position it will take real surgery to fix it. However depending on the problem, sometimes minor irregularities can be hidden with fillers such as in the "non-surgical nosejob".

Trauma to the nose can cause a displaced nasal fracture of the nasal bones, dislocation of the upper lateral cartilages off of the nasal bones, twisting of the nasal tip cartilages, and a fracture of the septum known as a deviated nasal septum. Once the nose has been fractured and twisted, it is very solid and cannot be manipulated back into position without surgery. A rhinoplasty procedure and possibly a septoplasty procedure is performed to straighten the nasal bridge line including the upper lateral cartilages, the lower lateral cartilages, and the nasal bones and to improve the deviated septum. Look for a double board certified ENT/facial plastic surgeon with extensive experience in fixing broken noses for best results. A cast will need to be applied across the bridge of the nose for one week. The surgery is performed under general anesthesia as an outpatient surgical procedure.

I would definitely not recommend getting punched as this is a very uncontrolled method of trying too straighten a crooked nose. Straightening a crooked is not easy--probably one of the more difficult things to do.
