By this age, social reinforcement generally is adequate to keep the child involved in the task long enough to obtain pure tone air and bone conduction thresholds. There are some variants of this procedure that have been developed. ...

Trauma to the Middle and Inner Ear October 2002
... Temporal bone trauma can be classified into blunt, penetrating, blast, and barotrauma. Blunt trauma to the skull occurs when there is a rapid collision between the head and a solid or semisolid object. The most common temporal bone fracture occurring from blunt trauma is the longitudinal fracture (8 ...
