Is it possible to fix a nose that was broken long time ago and did not heal properly?

It is certainly acceptable to undergo rhinoplasty for a broken nose that occurred many years ago. To straighten a curved nose, medial and lateral osteotomies must be performed. In many instances a cartilage spreader graft will be inserted underneath the upper lateral cartilage on the concave side to give symmetry or improve airflow. 

Yes, your nose can be fixed.  It is very common for patients to seek cosmetic rhinoplasty who have had nasal trauma in the past.  The nasal bones will need to be refractured in order to straighten the nose and reestablish symmetry.  The septum may also have been injured, with septal deviation causing the nose to appear crooked.  Septoplasty will serve to straighten the deviated septum providing not only cosmetic improvements, but also functional improvements in the way of better nasal air flow as well.  I suggest you follow up with a board certified surgeon who specializes in rhinoplasty surgery.   Good Luck

It is possible to fix the nose even though the injury was in the distant past.Find a plastic surgeon with ELITE credentials who performs hundreds
of rhinoplasties and rhinoplasty revisions each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA
