Using a 4K-3D Exoscope for Upper Airway Stimulation Surgery: Proof-of-Concept

Objective: Demonstrate the potential of the 4K-3D exoscope during upper airway stimulation surgery (UAS). Methods: A proof-of-concept study was performed to evaluate the feasibility of the exoscope during three consecutive UAS. Results: The exoscope was employed during UAS including cuff electrode and sensing lead placement. Three cases were successfully completed without adverse perioperative event; mean operative time was 200 minutes (range 188-218 minutes) with a successive reduction in operative time. Conclusion: This experience demonstrates the potential viability of the exoscope for UAS; it is a safe, innovative, and effective alternative or adjunct to existing visualization modalities. Notable advantages include improved ergonomics, unobstructed surgical field access, wide depth of field visualization, and short learning curve. Future technological enhancements could allow the exoscope to become a promising next-generation tool in the armamentarium of the contemporary sleep surgeon.
