Area of Science:

  • Neurosurgery
  • Medical Device Technology

Background:

  • Traditional awake craniotomy often requires cranial fixation, which can be uncomfortable for patients.
  • Existing methods may limit patient head mobility during surgery.

Purpose of the Study:

  • To describe a new technique for performing awake craniotomy without cranial fixation.
  • To evaluate the use of the Medtronic Stealth spinal reference array in this context.

Main Methods:

  • A Medtronic Stealth spinal reference array (four-point H-shaped LED array) was attached to a Yasargil footplate using a swingarm.
  • The footplate was affixed to the cranium post-craniotomy, followed by stereotactic registration.
  • The patient was awakened after registration, allowing head movement.

Main Results:

Related Experiment Videos

  • The described technique allows for awake craniotomy without the need for Mayfield pin head rest fixation.
  • The reference array maintains accuracy despite patient head movement.
  • This facilitates greater patient comfort and procedural adaptability.

Conclusions:

  • The Medtronic Stealth spinal reference array enables a novel, fixation-free approach to awake craniotomy.
  • This technique enhances patient comfort and maintains surgical accuracy.
  • It offers a promising alternative for specific neurosurgical procedures.
