Deformity of the nose due to collapse of septum

The picture shows a saddle nose deformity due to collapse of cartilagenous or bony bridge. Syphilis from birth and tuberculosis are reasons for collapse of bony bridge. Inadvertent surgery of the septum ,use of cocaine in the nose, infection of the cartilagenous septum (septal abscess) are reasons for collapse of cartilagenous bridge. Surgical correction of this deformity needs dissection of skin and placing a cartilage graft harvested from chest wall under the skin.This operation is done under general anesthesia. Inner and outer dressings are used. (inner to be removed in three days, outer to be removed in two weeks.)There is no visible scar.
