Longitudinal vs transverse petrous temporal bone fracture
Updates to Article Attributes
Body
was changed:
Temporal bone fractures generally refers to involvement of petrous part of temporal bone and are classically divided into longitudinal and transverse fracture depending on the direction of fracture plane with respect to long axis of petrous temporal bone. Some features may aid in distinguishing them.
Longitudinal (Middle ear fracture)
- Most common of all petrous temporal bone fracture (70-90%)
- Fracture line is parallel to the long axis of petrous temporal bone.
- Labyrinth are spared
- Ossicles are involved resulting in conductive hearing loss.
- Involvement of Tympanic membrane.
- Facial nerve involvement (~25%)
Transverse (Inner ear fracture)
- Less common temporal bone fracture (20-30%)
- Fracture line is perpendicular to the long axis of petrous temporal bone.
- Labyrinth are involved resulting in sensorineural hearing loss.
- Ossicles and the tympanic membrane are spared.
- Facial nerve involvement (~50%)
