Perforated nasal septum. Forceps holding open a nostril to give a view of a hole in the nasal septum of a 71-year-old man. The septum is the wall inside the nose that divides it into two nostrils. Perforation can arise due to trauma, drug abuse, an abscess or certain diseases, such as Wegner granulomatosis. Treatment includes surgical closure, which often fails, or insertion of a specially designed septal button in the hole. The cause of this perforation is unknown.
