Objectives:
To describe the value of high resolution computed tomography scan (HRCT scan) in post traumatic hearing loss.
Method:
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.
Conclusion:
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.
