Lateral plating of the temporal bone: Hemostatic technique for complex transverse fractures of the petrous temporal
1Section of Neurosurgery, Dept. of Surgery, University of Manitoba, Winnipeg, MB, Canada.
Background:
Transverse petrous temporal bone fractures are commonly associated with significant intracranial trauma. Diastases of these fractures can lead to issues with hemostasis in the setting of venous sinus or petrous internal carotid artery (ICA) injuries.
Objective:
To describe a rare case of a severe displaced transverse petrous temporal bone fracture with impending intra-operative exsanguination, treated with fracture reduction and lateral plating in order to achieve hemostasis.
Methods:
We retrospectively reviewed the records of a patient admitted to the neurosurgical department with a hyperacute epidural hematoma (EDH) secondary to a transverse petrous temporal bone fracture with venous sinus and petrous ICA injuries.
Results:
A 22 year old male was admitted for a severe traumatic brain injury leading to a left displaced transverse petrous temporal bone fracture and a hyperacute EDH. Given the location of the fractures, injury to the venous sinus (at the area of the transverse-sigmoid junction) and petrous ICA was suspected.Intra-operatively, significant blood loss from both the venous sinus and petrous ICA was encountered. Given the displaced temporal bone fracture, packing of the areas was impaired.We performed a manual reduction of the temporal fracture, followed by lateral plating in order to achieve hemostasis from the petrous ICA and aid with packing of the venous sinus injury.
Conclusions:
Reduction and lateral plating of displaced transverse petrous temporal bone fractures can aid significantly with intra-operative hemostasis in the extreme case of venous sinus and/or petrous ICA injuries.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...
