Saddle nose is caused by conditions that weaken or perforate the nasal septum including prior septoplasty, botched rhinoplasty, recreational drug use, medical conditions such as granulomatosis with polyangiitis, congenital syphilis and trauma.
But the majority of causes of saddle nose are due to Nasal trauma and surgical causes.
Saddle nose by injury or trauma
Any sort of injury or trauma to the nose can damage the septal cartilage along the bridge and compromise important support structures.
Athletes, especially in sports with extrame physical contact, like boxing and hockey, are prone to these kinds of injuries.
Saddle nose after rhinoplasty (septoplasty)
Rhinoplasty surgery that is overaggressive can be a contributing cause if excess cartilage is removed from the nose in an attempted to reduce the height of the bridge.
There may no longer be sufficient bone and cartilage which can result in the collapse of the middle portion of the nasal bridge.
Causes by prior Rhinoplasty (Septoplasty)
In this case, use Rib grafting methods.
Because reconstruction surgery of making nasal septum again is required.
If nasal septum cartilage is in complete loss, surgery should be done using patient’s rib cartilalge.
If patient does not desire harvesting from his or her own rib area, donated rib can be used. (Irradiated rib grafts from blood banks)
