Saddle nose deformity is a condition associated with nasal trauma, congenital syphilis, relapsing polychondritis, granulomatosis with polyangiitis, cocaine abuse, sarcoidosis,and leprosy, among other conditions.
Its most common cause is nasal trauma.
It is characterized by a loss of height of the nose, because of the collapse of the bridge.
It may involve bony, cartilaginous or both components of the nasal dorsum.
Saddle nose deformity can usually be corrected with augmentation rhinoplasty.
Augmentation occurs by filling the dorsum of nose with cartilage, bone or synthetic implant.
Cartilage can be taken from the nasal septum or auricle and laid in single or multiple layers.
If deformity involves both cartilage and bone, cancellous bone from iliac crest is the major source of replacement.
Autografts are preferred over allografts.
