In general, noses don’t change their overall shape.  However, there are a few points to be made here.  One is that in general, patients with thin nasal skin will find over time that the skin will get even thinner; as if it “shrink wraps” onto the underlying cartilage and bone.  In this instance, any slight irregularity will become very obvious.  During rhinoplasty perichondrium (lining of the nasal septal cartilage) or fascia (thin lining of muscle) can be strategically placed as a thin buffer between the nasal skin and the underlying cartilage or bone, preventing the severe thinning/shrink wrapping that can eventually occur.
