Preliminary Clinical Experience with a High-Definition Three Dimensional Exoscope for Spinal Surgery

We retrospectively evaluated spinal surgeries performed using the high-definition three-dimensional exoscopic system, which became available at our institution in August 2020. Eleven patients (4 with cervical disease and 7 with lumbar disease) underwent surgery with the system. There were no surgical complications related to the system, and the results were satisfactory. The small, flexible camera of the exoscope allows the surgeon to view the surgical field from various angles, facilitating both the approach and technique. In addition, it allows the surgeon to operate in an upright position without strain on the head and neck. Although further surgical experience is needed, this system has the potential to improve the visualization of the surgical field in spinal surgery.
