In this prospective single centre study, patients who underwent a head CT were included and a concomitant TCS performed. As a rule, the conservative treatment was our first treatment option and the surgical option was performed on the basis of GCS and the neuroimaging findings (Volume, location, mass effect, and degree of midline shift). The first option was to delay treatment until all permanent teeth have erupted and then use fixed appliance either passive self-ligating system or conventional bracket. We found a strong correlation between a midline shift exceeding the thickness of the hematoma by 3 mm or more, and subsequent mortality. o "Midline shift with brain compression" is more specific—and AUDIT-PROOF. The authors sought to utilize the Citicoline Brain Injury Treatment (COBRIT) trial to analyze patient recovery over time depending on degree of midline shift at presentation. A Visual Perceptual Midline Shift Syndrome may exist with behaviors associated with dizziness, vertigo, visual field cuts, and visual neglect. If an epidural hematoma (or any other intracranial condition for that matter) is suspected a CT scan should be obtained promptly.
