Summary
This study introduces Sinoforce, a novel instrument for measuring surgical forces during endoscopic sinus surgery (ESS). It helps surgeons apply appropriate instrument forces for safer procedures, especially near vital structures.
Area of Science:
- Otolaryngology
- Surgical Technology
- Biomechanics
Background:
- Endoscopic sinus surgery (ESS) requires precise psychomotor skills and controlled force application.
- Minimizing surgical force is crucial when operating near vital structures like the skull base to prevent complications.
Purpose of the Study:
- To develop and evaluate a novel instrument, Sinoforce, for measuring surgical forces during ESS.
- To provide surgeons with real-time feedback on applied forces for enhanced surgical safety.
Main Methods:
- Development of Sinoforce: modified Blakesley forceps with integrated force sensors.
- Pilot study using four cadaveric head specimens to measure forces applied during endoscopic ethmoidectomy.
- Measurement of breakthrough forces for ethmoidal bony labyrinth and skull base structures.
Main Results:
- Sinoforce provides real-time visual display of forces applied during ESS.
- Comparable forces were required to breach the ethmoidal bulla and uncinate process.
- Forces exceeding 2 kg, beyond the instrument's calibration, were needed for skull base penetration.
Conclusions:
- Sinoforce is a promising instrument for quantifying surgical forces in ESS.
- Understanding force application can improve surgical technique and reduce complication risks.
- Further studies are warranted to explore the full benefits of Sinoforce in clinical settings.
