LONGITUDINAL TEMPORAL BONE FRACTURE
POSTERIOR WALL
| Description |
: |
The ossicular chain usually remains intact in this type of fracture, and the conductive deafness which is the result of bleeding into the middle ear usually passes as the blood is resorbed.
Facial nerve weakness or paralysis develops in less than 25% of cases and is usually temporary.
The site of injury to the facial nerve frequently is found in the area of the geniculate ganglion, although there may be additional injury in the mastoid segment in about 20% of cases. |
