Initial Experience With Ultra-High-Definition 3D Exoscope in Thyroid and Parathyroid Surgery.

Background: Operation with a 3D exoscope has recently been introduced in clinical practice. The exoscope consists of two cameras placed in front of the operative field. Images are shown on a large 3D screen with high resolution. The system can be used to enhance precise dissection and provides new possibilities for improved ergonomics, fluorescence, and other optical-guided modalities.

Methods: Initial experience with the ultra-high-definition (4K) 3D exoscope in thyroid and parathyroid operations. The exoscope (OrbEye^TM) was mounted on a holding system (Olympus).

Results: We used the exoscope in parathyroidectomy (N = 6) and thyroidectomy (N = 6). Immediate advantages and disadvantages were discussed and recorded. The learning curve for use of the exoscope may be shorter for surgeons with training in endoscopic or robotic procedures. There may be improved ergonomics compared with normal open-neck operations. Further, the optical guided operations can be used with fluorescence and have potential for different on-lay techniques in the future. The 4 K 3D image quality is state-of-art and is highly appreciated during fine surgical dissection and eliminates the need for loupes.

Conclusion: In several ways, using the ORBEYE™ in thyroid and parathyroid surgery provides the surgical team with a new and enhanced experience. This includes improved possibility for teaching, surgical ergonomics, and a 4K 3D camera with a powerful magnification system. However, it is not clear if utilization of these features would improve surgical outcomes. Furthermore, the ORBEYE™ lacks incorporation of parathyroid autofluorescence, and the current costs for the system do not facilitate general access to exoscope assisted operations.
