Those noses with very thin dermis of nasal skin cover, scarce subcutaneous fat, already somehow transparent and showing internal natural skeletal structures through the skin, particularly at the nasal dorsum and the nasal tip, are prone to let the surgical techniques of rhinoplasty be externally visible and therefore build up certain irregularities, ridges, buckling, tombstone deformity, etc.
As prevention or once the irregularities have been produced it might be indicated adding on their top and beneath the skin camouflage layers like perichondrium or temporalis fascia grafting.
