Traumatic Lesions of the Temporal Bone
The head is affected in almost 75% of road accidents and if severely injured, the ear is the most frequently damaged sensory organ. Until recently, it was thought that nothing could be done to correct the hearing loss caused by skull traumas. Obviously, hearing loss due to petrous fracture cannot be corrected and radiological examination is concerned with such factors as damage to the facial nerve and the site of a CSF fistula. It is now realised, however, that traumatic hearing loss is often due to disruption of the ossicular chain, and although radiological demonstration may be difficult such an examination can greatly assist reconstruction. Ossicular discontinuity should always be considered where conductive deafness persists following head injury.
