Post traumatic dislocation of Incus into the external acoustic canal : a rare case report.

Dr. Nilesh Gupta, Dr. Manish Meshram

Abstract :

We report a rare case of dislocation of incus into the external acoustic canal following a fall from stairs with head injury. CT scan revealed disrupting the Ossicular chain with disarticulation of malleolo–incudal joint and dislocation of incus. A bony fragment, giving appearance as shape of incus, noted in the postero–inferior region of right external ear canal. Micro–Otoscopy, 10 days after injury, revealed an intact tympanic memane covering the fractured – dislocated incus. The fractured segment was displaced and attached to the postero–inferior aspect of the external auditory canal. Further the bone extraction surgery was performed and the diagnosis confirmed.
