What is Trauma Craniotomy?

A trauma craniotomy is a surgical procedure performed on the skull to address acute head injuries or traumatic brain injuries (TBIs). It involves the temporary removal of a segment of the skull, known as a bone flap, to access and treat the injured brain tissue. This procedure is typically performed in emergency situations when there is significant bleeding, swelling, or other life-threatening conditions within the brain.

Indications for Trauma Craniotomy

Trauma craniotomy may be indicated in cases of acute head trauma or traumatic brain injury when there are critical conditions that necessitate immediate medical intervention. Some of the common indications for trauma craniotomy include:

  • Intracranial Hemorrhage: When there is bleeding within the skull, such as epidural hematoma, subdural hematoma, or intraparenchymal hemorrhage, a trauma craniotomy may be performed to evacuate the blood and relieve pressure on the brain.
  • Brain Swelling: Severe head trauma can lead to brain swelling, causing increased intracranial pressure. Trauma craniotomy may be necessary to provide additional space for the swollen brain tissue and prevent further damage.
  • Contusion or Brain Injury: In cases of significant brain contusion or other traumatic injuries to the brain tissue, a craniotomy may be performed to remove damaged tissue, control bleeding, and reduce the risk of secondary brain injury.
  • Skull Fractures: Compound or depressed skull fractures may require surgical intervention. In some cases, a trauma craniotomy is performed to repair or remove fractured bone fragments.
  • Open Skull Fractures: When there is an open or compound skull fracture, where the bone is broken and the overlying skin is disrupted, surgical intervention may be necessary to clean the wound, remove bone fragments, and address any underlying brain injuries.
  • Emergency Decompression: In emergency situations where there is a rapid increase in intracranial pressure due to various traumatic factors, a trauma craniotomy may be performed as a life-saving measure to quickly relieve pressure and prevent further damage to the brain.

Preparation for Trauma Craniotomy

In general, preoperative preparation for trauma craniotomy will involve the following steps:

  • A review of your medical history and a thorough examination are performed by your doctor to check for any medical issues that need to be addressed prior to the surgery.
  • Diagnostic tests such as blood work and imaging to help detect any abnormalities that could compromise the safety of the procedure.
  • You will be asked if you have allergies to medications, anesthesia, or latex.
  • You should inform your doctor of any medications or supplements that you are taking or any conditions you have such as heart or lung disease.
  • You may be asked to avoid medications such as blood thinners or anti-inflammatories for a specific period prior to surgery.
  • You are advised to abstain from smoking for a defined period before and after surgery as smoking may cause breathing issues during the surgery, as well as slow down the healing process.
  • You should not consume any solids or liquids at least 8 hours prior to surgery.
  • You should arrange for someone to drive you home after surgery.
  • A signed informed consent will be obtained from you after the pros and cons of the surgery have been explained.

Procedure for Trauma Craniotomy

The trauma craniotomy procedure is usually performed under general anesthesia and takes about 3 to 5 hours or longer. In general, the procedure involves the following steps:

  • You will be placed on the operating table in a way that gives your surgeon the best access to the side of the brain to be operated on.
  • Your head will be shaved, and the surgical site will be cleaned with an antiseptic solution.
  • An intravenous (IV) line will be inserted into your hand or arm to administer general anesthesia, medicines, and fluids. Anesthesia helps you sleep throughout the surgery and not feel any pain.
  • Your anesthesiologist will continuously monitor your vital signs throughout the surgery.
  • Your head will be held in position by a Mayfield head holder or a similar device until the end of the surgery.
  • Based on the location of the treatment area, an incision is made to remove the portion of the skull. Your surgeon may use special instruments such as a medical drill and a saw to make burr holes and cut the skull bone accordingly.
  • The dura mater (outer covering of the brain) under the skull is cut open to expose the brain and the dura folds are secured with retractors.
  • Your surgeon assesses the brain for injuries, such as contusions, hematomas, or swelling, and takes appropriate measures to address these issues. This may include removing damaged tissue, draining fluid or blood, or using other techniques to alleviate pressure.
  • Once the necessary procedures are completed, the bone flap is carefully replaced and secured in its original position using plates, screws, or other fixation methods.
  • The scalp incision is then closed with surgical staples or stitches, and a sterile dressing or bandage is applied to complete the operation.

Postoperative Care and Recovery

In general, postoperative care instructions and recovery after a trauma craniotomy will involve the following steps:

  • You will be transferred to the recovery area where the medical staff will closely monitor your vital signs and neurological status to assess your brain function.
  • The length of hospital stay varies from 2 to 3 days to a week or more depending on the surgery and any complications.
  • You may experience pain, inflammation, and discomfort in the operated area. Medications are prescribed as needed to manage these, along with antibiotics to address the risk of surgery-related infection.
  • Antiepileptic medications may be prescribed to prevent seizures, which can be a concern following traumatic brain injuries.
  • Measures may be taken to manage cerebral edema (swelling of the brain), such as elevation of the head of the bed and the use of medications to control intracranial pressure.
  • Maintaining proper fluid and electrolyte balance is important. Intravenous fluids may be administered to prevent dehydration and maintain optimal physiological function.
  • Instructions on surgical site care and bathing will be provided to keep the wound clean and dry once discharged from the hospital.
  • Early mobilization and rehabilitation may be initiated as soon as your condition allows. Physical therapy, occupational therapy, and speech therapy may be components of the rehabilitation plan.
  • Refrain from strenuous exercises or activities and lifting any heavy objects until approved by your physician. A gradual increase in activities over a period of time is recommended. You may take many weeks to return to your previous level of strength and energy.
  • Refrain from driving until you are fully fit and receive your doctor’s consent.
  • A periodic follow-up appointment will be scheduled to monitor your progress.

Risks and Complications

While trauma craniotomy is a potentially life-saving surgical procedure, it is not without risks and complications. Some common risks and complications associated with trauma craniotomy include:

  • Infection
  • Bleeding
  • Swelling and edema
  • Functional impairments
  • Cerebrospinal fluid (CSF) leakage
  • Seizures
  • Adverse reactions to anesthesia/medications
  • Hematoma formation (a collection of blood outside blood vessels) within the brain or at the surgical site
  • Blood clot formation, which can lead to complications such as stroke or embolism
