The nose continues to develop in both its cartilaginous and bony components. It does so via a numer of different growth centres that have a dedicated blood supply. The growth continues significantly until at least 16-17 years of age.

Surgery to the nasal septum and nasal bones disrupts the blood supply to these growth centres and as a result most patients aged below 17 would not be considered for a nosejob before this age. This is not to say that it should not be done as sometimes if there is a trauma causing a significant injury to the nose and distortion of shape it is better to correct this rather than let the nose continue to grow in the wrong fashion for the rest of the deveoment of the nose.
