A nose can be crooked for one of two reasons:
1. It grew that way, or
2. It was fractured, or encountered some other type of trauma such as previous surgery.
The first problem is more difficult to fix because of certain inherent deficiencies in the nasal anatomy. The second one (nasal fracture) is easier to fix because the proper anatomy is present, but it has been shifted. Surgery can usually shift the nose back into a good position. While we as surgeons always strive for perfection, it is important for the patient not to expect it as a fractured nose may always have some minor irregularities. Good luck.
