The usual cause of perforated eardrum is trauma, such as the deliberate or accidental insertion of foreign objects (cotton swabs or bobby pins) or sudden excessive changes in pressure (explosion, a blow to the head, flying, or diving). The injury may also result from untreated otitis media and, in children, from acute otitis media.

Generally, perforated septum is caused by traumatic irritation, most commonly resulting from excessive nose picking; less frequently, it results from repeated cauterization for epistaxis or from penetrating septal injury. It may also result from perichondritis, an infection that gradually erodes the perichondrial layer and cartilage, finally forming an ulcer that perforates the septum. Other causes of septal perforation include syphilis, tuberculosis, untreated septal hematoma, inhalation of irritating chemicals, cocaine snorting, chronic nasal infections, nasal carcinoma, granuloma, and chronic sinusitis.
Deviated septum commonly develops during normal growth, as the septum shifts from one side to the other. Consequently, few adults have perfectly straight septa. Nasal trauma resulting from a fall, a blow to the nose, or surgery further exaggerates the deviation. Congenital deviated septum is rare.
