[Computerized tomographic evaluation of traumatic ossicles disruption].
OBJECTIVE
To investigate the importance of the high resolution computerized tomography of temporal bone in evaluation of traumatic lesions, particularly of the ossicular disruption.


METHODS
Ten patients with traumatic ossicles dislocation underwent preoperative CT scanning followed by surgical exploration of the middle ear.


RESULTS
The radiographic finding was consistent with the operative demonstration for malleoincudal disarticulation (3 ears), incudostapedial dislocation (7 ears), and the fracture of temporal bone (8 ears).


CONCLUSIONS
The incus was the most vulnerable ossicle in the trauma to the middle ear. CT scans can diagnose exactly the damage position in middle ear.
