Summary

This study looks at 2,000 people with a type of brain bleed called an epidural hematoma to see which surgery works best. Researchers will track recovery over time using a scale that measures how well people can function. The goal is to find the safest and most effective surgical approach.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Clear medical history of traumatic brain injury; 2. within 12 hours after injury; 3. Supratentorial unilateral acute epidural hematoma on first head CT scan examination; 4. The admitting neurosurgeon considers that the epidural hematoma needs to be evacuated with surgical treatment; 5. With informed consent to surgery and trial participation. Exclusion Criteria: 1. Previous intracranial surgery prior to trauma; 2. Patients with a score of 3 on the GCS, with bilateral fixed and dilated pupils, bleeding diathesis or defective coagulation, or an injury that was deemed to be unsurvivable; 3. CT demonstrates associated other intracranial hematomas e.g. subdural, intracerebral hemorrhage, or large size infarction, which are the main causes of operation; 4. Patients who had injury of the oculomotor nerve; 5. Severe pre-existing disability or severe co-morbidity which would lead to a poor outcome even if the patient is supposed to a good recovery from the TBI; 6. Pregnant female.
