Elevation of Depressed Skull Fracture – Procedure Guide
Elevation of Depressed Skull Fracture – Procedure Guide Elevated depressed skull fractures are a serious form of traumatic brain injury requiring prompt and precise surgical intervention. These fractures occur when a fragment of the skull is displaced inward, often caused by blunt force trauma, leading to potential brain tissue damage, bleeding, and increased intracranial pressure. Managing such injuries involves a meticulous surgical procedure aimed at removing the fractured bone segment, controlling hemorrhage, and preventing secondary brain injury.
The initial step in the management of an elevated depressed skull fracture is thorough assessment and stabilization of the patient. This includes ensuring airway patency, adequate breathing, and circulation — the ABCs of trauma care. Neurological assessment using scales such as the Glasgow Coma Scale helps determine the severity of brain injury and guides urgency. Imaging studies, particularly a computed tomography (CT) scan, are essential to delineate the extent of the skull fracture, the degree of depression, and associated brain injuries such as hematomas or contusions.

Elevation of Depressed Skull Fracture – Procedure Guide Once stabilization and diagnosis are confirmed, surgical planning begins. The primary goal of the procedure is to elevate the displaced skull fragment to restore the normal contour of the skull and prevent ongoing brain compression. The patient is typically positioned supine with the head secured in a neutral position, ensuring optimal access to the fracture site. Under general anesthesia, a scalp incision is made—usually a curvilinear or linear incision over the fracture site—followed by careful dissection through the galea and scalp layers to expose the fracture line.

It is crucial to inspect for dural tears, which are common in these injuries, as they can lead to cerebrospinal fluid leaks or infections. If a dural tear is present, it is repaired using fine sutures or dural substitutes to prevent cerebrospinal fluid leakage and reduce infection risk. The depressed skull fragment is carefully lifted using specialized instruments such as elevators or curettes, applying gentle force to avoid further damage to brain tissue.

Sometimes, additional fixation using plates and screws or sutures may be necessary to secure the bone and prevent re-depression. Hemostasis is meticulously achieved throughout the procedure to control bleeding, and any hematomas are evacuated to reduce intracranial pressure.
The wound is irrigated with sterile saline to clear debris, and the scalp is closed in layers, ensuring good alignment and tension-free suturing to promote healing. Postoperative care involves close neurological monitoring, imaging to confirm proper elevation, and management of intracranial pressure. Antibiotics and anticonvulsants are often administered as prophylaxis against infection and seizures. Elevation of Depressed Skull Fracture – Procedure Guide
Early intervention in depressed skull fractures significantly reduces the risk of complications such as infection, brain abscess, or persistent neurological deficits. The success of the procedure hinges on surgical precision, promptness, and comprehensive care, underscoring the importance of experienced neurosurgical teams in managing these complex injuries.
