Lateral plating of the temporal bone: Hemostatic technique for complex transverse fractures of the petrous temporal bone
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
