Summary
A new robotic system precisely perforated the sphenoid sinus anterior wall in cadavers. This advancement in endoscopic paranasal sinus surgery offers enhanced safety and accuracy for complex procedures.
Area of Science:
- Neurosurgery
- Robotic Surgery
- Endoscopic Sinus Surgery
Background:
- Severe complications in endoscopic paranasal sinus surgery, though rare, can be fatal.
- Optic nerve and internal carotid artery injuries often result from penetrating the sphenoid sinus anterior wall.
Purpose of the Study:
- To evaluate a novel robotic system for precise automated perforation of the sphenoid sinus anterior wall.
- To assess the safety and accuracy of robotic-assisted endoscopic paranasal sinus surgery.
Main Methods:
- A robotic system, "A 73", featuring a 4-canal-microendoscope and specialized instruments was utilized.
- Fully automated perforation of the sphenoid sinus anterior wall was performed on five cadaveric specimens.
Main Results:
- Successful perforation of the sphenoid sinus anterior wall was achieved in all specimens without damaging surrounding structures.
- Submillimeter accuracy was demonstrated in transformation error and intraoperative precision analyses.
- The surgical approach was safely enlarged using telemanipulation mode.
Conclusions:
- The developed robotic system enables precise and reproducible automated perforation of the sphenoid sinus anterior wall.
- This robotic approach enhances safety in endoscopic paranasal sinus surgery.
- The system allows for subsequent enlargement of the surgical approach via telemanipulation.
