Abstract
- Classically, fractures of the labyrinth are commonly divided into longitudinal, transverse, and oblique fractures. (a) Longitudinal fractures are parallel to the petrous axis, and are the result of traumata of the temporo-parietal region. The line of fracture comes down from the temporo-parietal region, passes at the level, or in front, of the external acoustic meatus, and ends at the foramen lacerum, or at the foramen spinosum, after running along the grooves of the petrosal nerves. The petrous bone is thus divided into two parts: an external one containing the anterior part of the tympanic cavity proper and a posterior one containing the Fallopian canal, the internal acoustic meatus, the internal ear, and part of the antrum. The tympanum is torn, hence otorrhagia, the internal ear is intact and, generally, the facial nerve is also free from injury. As a rule, this line of fracture is fairly wide. (b) Transverse fractures are the result of a trauma of either the occipital or the occipitomastoid regions; ...
