Exoscopic supracerebellar approach to the pineal region

The advent of the 3D exoscope represents a significant technological breakthrough in contemporary surgical practice. While the operating microscope has long been the preferred surgical visualization tool, its limitations in accessibility and ergonomics have prompted the development of a more advanced, 3D version [1,2]. The 3D exoscope has been one such recent development aimed at addressing these limitations. By delivering intense illumination and magnification to the deepest parts of the surgical field, 3D exoscopes are high-definition digital camera systems that give surgeons high-magnification views of the operative field [2]. Additionally, the design of the 3D exoscope allows for improved surgeon ergonomics, decreasing overall fatigue while providing a similar view of the procedure for all personnel in the operating room [3,4]. In this article, we discuss the advantages and limitations of the 3D exoscope in neurosurgery and highlight its use in a patient case. This is a case of a 25-year old female who was noted to have an incidental 13 mm pineal cystic mass on imaging work up for a first time generalized seizure. We discuss the use of an exoscopic supracerebellar approach to the pineal gland for resection of the mass and highlight the various considerations for use of an exoscope in such a case.
