Imaging Procedures and Findings
Axial CT scan from petrous demonstrates transverse Fx of temporal bone . Fracture line involves vestibule and second part of facial nerve . Note mastoid air cells opacification and occiputotemporal suture diastasis.
Fractures of the temporal bone can be classified as longitudinal or transverse depending on their orientation relative to the long axis of the petrous bone. fractures perpendicular to the long axis of the petrous bone are termed ??transverse?Â fractures. The transverse temporal bone fracture usually results from a blow to the occiput or frontal region. Complications are usually more severe and include sensorineural hearing loss, severe vertigo, nystagmus, and perilymphatic fistula. Facial palsy is seen in 30% to 50% of these cases and is often complete . Transverse fractures may also involve the carotid canal or jugular foramen, causing injury to the carotid artery or jugular vein.
