High-definition 3D exoscope in thyroid surgery

Background: The high-definition 3D exoscope is an innovative and promising tool that was recently introduced in the clinical practice. It may be used during open surgical procedures to enhance the ability to perform precise dissection of fine structures. We describe our preliminary experience with the 3D exoscope in thyroid surgery, discussing potential advantages of this system. Methods: A high-definition 3D exoscope (3D VITOM®) mounted on the VERSACRANETM holding system (Karl Storz, Tuttlingen, Germany) was used to perform open thyroid surgery. Results: The 3D exoscope was used in three patients without significant intra-operative delay or complications. Both thyroidectomy and central compartment dissection were performed. The 3D exoscope allows to perform precise dissection in the identification and preservation of the recurrent laryngeal nerve and the parathyroid glands. Conclusions: 3D exoscope-assisted thyroid surgery seems to be feasible and safe. Further studies should be encouraged to analyze potential clinical benefit in the post-operative period.
