Everyone has facial asymmetry. Differences between the left and right sides due to facial asymmetry become more noticeable as the nose becomes larger. There are limits to how much correction is possible for differences caused by this kind of asymmetry.
However, if the tip of the nose has rotated or the silicone has shifted based on the facial midline, revision surgery can help.
When correcting a crooked nose, three things must be considered: the nasal tip, the silicone, and the nasal bone.
If the silicone has shifted, the symmetry of the bones on the left and right sides is important. By correcting the deviated bones and fixing the silicone back in the proper position, the asymmetry can be corrected.

If the nasal tip or the columella has rotated, it is important to check the position and curvature of the septum supporting the nose, and then correct it. In many cases, correcting this requires a firm material such as rib cartilage.

If the nasal bone is crooked, it is best to minimize left-right asymmetry by performing osteotomy on the protruding area based on the facial midline and pushing it inward.

If the above three factors are carefully considered and corrected, a good result can be achieved.
