The exoscope has been introduced as an alternative to microscopes or endoscopes. We used a 3D, HD exoscope (3D Vitom®, Karl Storz, Tuttlingen, Germany) in two patients undergoing two-level ACDF for cervical myelo-radiculopathy. METHODS:
The exoscope was used during soft-tissue dissection, discectomy, osteophytectomy and cage insertion. Microsurgical drilling of posterior osteophytes, which usually requires adequate magnification and proper microscope angulation, was also performed with the exoscope.
Exoscope provided a 3D view of the surgical field similar to a microscope and allowed us to effectively and safely perform the above surgical steps. The main advantage of 3D exoscope-assisted surgery, compared to microscope-assisted surgery, is the possibility to generate videos with a similar view and image quality as perceived by the surgeon; therefore, the didactic capabilities of exoscopic videos are greater than those provided by microscopes. Exoscopes are also smaller compared to microscopes: this allows for comfortable use from early surgical steps to device implantation.
Barbagallo et al., think that exoscope-assisted surgery may become a safe and effective alternative to microscope-assisted surgery in ACDF 1).
