Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Skull Base Surgery

Background:

  • Advancements in image guidance, endoscopy, and instrumentation have propelled keyhole neurosurgery.
  • The supraorbital keyhole approach represents a significant development in minimally invasive neurosurgical techniques.

Purpose of the Study:

  • To describe the concept and surgical technique of the supraorbital keyhole approach.
  • To highlight the benefits of this approach in accessing skull base lesions.

Main Methods:

  • The procedure involves an eyebrow incision and a limited supraorbital craniotomy.
  • Image guidance assists in determining the optimal surgical trajectory.
  • Endoscopy and specialized instruments facilitate visualization and manipulation within the narrow surgical corridor, avoiding brain retractors.

Main Results:

  • The supraorbital keyhole approach allows for effective mobilization of the frontal lobe.
  • It provides direct access to the central skull base.
  • The technique enables precise manipulation through a limited surgical corridor.

Conclusions:

  • The supraorbital keyhole approach is a safe and effective method for accessing selected skull base lesions.
  • This technique minimizes invasiveness while maintaining surgical efficacy.
