[Traumatic luxation of the stapes: radiology and surgical outcome].
OBJECTIVE
To describe the value of high resolution computed tomography scan (HRCT scan) in post traumatic hearing loss.


METHODS
HRCT scan of the temporal bone in millimetric cut with axial and coronal views was performed.


RESULTS
CT scan confirmed pneumolabyrinth with intact stapes depressed deeply into the vestibule. Surgical exploration was performed and the stapes was gently removed from the vestibule.


CONCLUSIONS
CT scan confirmed the diagnosis and studied the stapes integrity. Hearing deteriorated postoperatively is increased in case of stapes fracture. When a luxation of the stapes into the vestibule is suspected, it is important to determine how deeply and whether it is fractured. When such a case is encountered, high resolution CT scan of the temporal bone must be performed to confirm the diagnosis and to confirm integrity of the stapes.
