Traumatismos del hueso temporal

Abstract

Injuries to the temporal bone are caused by high energy mechanisms. Fractures, longitudinal or transverse, are the most frequent lesions and they need to be specifically searched. If the fracture is not visible, its presence is suspected by means of indirect signs, such as soft tissue occupation within mastoid cells, or in the tympanic cavity, and air in an abnormal situation. The ossicular chain can undergo luxations, being the most frequent the incudomallear joint, and fractures. For the study of traumatic injuries of the temporal bone, the CT scan should be the method of choice, especially by means of multislice technology, since the speed of acquisition, and the good quality of multiplanar reconstructions, facilitates the diagnosis.
