The nasal septum is the partition that separates the left and right nasal cavities, and is composed of the nasal septum cartilage in the front, the ethmoid vertical plate and vomer bones in the back, and the mucous membrane that covers them. A hole in this is called a nasal septum perforation. It most often occurs after surgery to correct a deviated nasal septum, but can also occur in association with syphilis, tuberculosis, collagen diseases that cause vasculitis, such as systemic lupus erythematosus (SLE), and Wegener's granuloma.
