The terrorist attack on 11 March caused a high percentage of patients with ear injuries. Shock waves provoke alterations to the external ear as well as to the middle and inner ear. The most frequent lesion is tympanic membrane perforation. Initial evaluation with otoscopy, acoumetry, tonal audiometry and vestibular examination was performed and was repeated after 2 and 3 months. In most patients there was a correlation between the grade of middle ear lesion and auditory damage. In most patients with tympanic rupture, the perforation was total or subtotal. Spontaneous closure can occur in some patients but is usually related to the size of the initial lesion. Thus in tympanic perforations of more than 50%, spontaneous closure is unlikely.
