Use of a 3D exoscope in microvascular decompression of the trigeminal nerve root

For microvascular decompression surgery, adequate visualization of the trigeminal nerve root is essential. Several visualization techniques with operating microscopes, endoscopes, a combination of both, and exoscopes have been described. In this video, the authors use a 4K 3D exoscope (ORBEYE) as it offers superb optical image quality with a high degree of magnification and illumination in the cerebellopontine angle. Other advantages are surgeon ergonomics, a very good depth of field for the entire operating team, and potentially evolving visualization technologies like narrow-band imaging-essential points for microvascular decompression surgery where the aim is to create the best possible visibility in a narrow corridor.
