ABSTRACT
Various types of ossicular chain interruption may occur in temporal bone fractures. The most common type is incudostapedial joint disruption. Incus is the most vulnerable to traumatic injury as compared with malleus or stapes, because it is suspended only by ligamentous structures and connected to the incudomalleolar and incudostapedial joints. Incus may rarely be pushed through tympanic membrane or pass through a fracture of posterosuperior external auditory canal. However, a case of complete extrusion of incus into the external auditory canal has not been reported. The author presents a rare case of incus extrusion into the external auditory canal with temporal bone fracture after head trauma.
