A Case of Incus Dislocation into the External Auditory Canal after Head Trauma / 대한이비인후과학회지

Temporal bone fracture is usually the result of blunt head injury as ossicular disruption or isolated dislocation of individual ossicles may occur after temporal bone trauma. The incus is particularly prone to displacement because of its fragile ligamentous support. We report a rare case of incus dislocation into the external auditory canal associated with an underlying temporal bone fracture.
