This preclinical cadaver study shows robotic-assisted skull base surgery is feasible. Further refinement of the da Vinci robotic system is needed for successful clinical application in skull base procedures.

Area of Science:

  • Neurosurgery
  • Robotic Surgery
  • Skull Base Anatomy

Background:

  • Skull base surgery presents complex anatomical challenges.
  • Minimally invasive techniques are continually being explored to improve patient outcomes.
  • Robotic systems offer potential advantages in precision and dexterity for complex surgical procedures.

Purpose of the Study:

  • To evaluate the feasibility of robotic-assisted surgical approaches to the skull base.
  • To determine optimal instrument configurations for robotic skull base dissection.
  • To assess setup and operative times for robotic skull base procedures in a cadaver model.

Main Methods:

  • A three-phase preclinical cadaver study was conducted.
  • Phase 1: Assessed surgical corridors for anterior and infratemporal skull base access.

  • Phase 2: Determined optimal da Vinci Surgical System instrument configuration.
  • Phase 3: Performed robotic-assisted cadaver dissection and recorded setup and operative times.

    • Main Results:

    • Feasible surgical corridors were identified via maxillary and nasal windows.
    • Optimal instrument angles and positions were established for different skull base regions.
    • Robotic setup times varied (23-95 minutes), with operative time averaging 63.5 minutes.
    • Integration of robotic and endoscopic techniques was demonstrated.

    Conclusions:

    • Robotic-assisted surgery is a feasible approach for skull base procedures.
    • The da Vinci system requires redesign for smaller size and improved articulation for clinical use.
    • Further research and technological advancements are needed for widespread robotic skull base surgery.
