This study demonstrates the feasibility of using an industrial robot for mastoidectomy, a surgical procedure in otologic surgery. The robotic system achieved high precision in bone ablation, paving the way for enhanced patient safety and reduced surgical times.

Area of Science:

  • Robotics in Surgery
  • Otologic Surgery
  • Image-Guided Interventions

Background:

  • Robotics is widely used in surgery, but not yet in otologic procedures.
  • Robots offer potential benefits like enhanced precision and reliability in surgical tasks.

Purpose of the Study:

  • To investigate the feasibility of using an industrial robot for performing mastoidectomy.
  • To assess the safety, effectiveness, and efficiency of robotic-assisted mastoidectomy using image guidance.

Main Methods:

  • A robotic system was developed integrating custom software with an industrial robot and an optical tracking system.
  • Computed tomographic (CT) scans of cadaveric specimens were used to plan the surgical path for bone removal.
  • Bone-implanted fiducial markers ensured accurate registration between CT imaging and the physical surgical space.

Main Results:

  • A mastoidectomy was successfully performed on three cadaveric specimens using a robotic system.
  • Postoperative CT scans revealed high percentages of target bone ablation (97.70%, 99.99%, 96.05%) without compromising critical anatomical structures.

Conclusions:

  • This study represents the first reported use of a robot for mastoidectomy.
  • While challenges exist for clinical translation, the robotic approach is feasible and shows promise for improving surgical outcomes.
  • Future research aims to advance robotic mastoidectomy for enhanced patient safety and reduced procedure times through machine precision.
