Perforated eardrum. Otoscope view of a perforated eardrum (tympanic membrane). The eardrum is the structure that transmits sound from the external ear to the middle and inner ears. Perforations can be caused by injury, or by ear infections. Perforated eardrums heal naturally once the underlying cause has been treated.
