Spinal navigation for small thoracic intradural tumors: The challenge between minimally invasive and exoscopic magnification

Background: Spinal navigation offers significant benefits in the surgical treatment of small thoracic intradural tumors. It enables precise tumor localization without subjecting patient to high radiation doses. In addition, it allows for a smaller skin incision, reduced muscle stripping, and limited bone removal, thereby minimizing risk iatrogenic instability, blood loss, postoperative pain, enabling shorter hospital stays. Case Description: This video presents two cases demonstrating application spinal technique tumors measuring <20 mm. first case, which involves calcified tumor, can be performed using 3D fluoroscopy or computed tomography images obtained intraoperatively. Notably, as illustrated second merging preoperative magnetic resonance imaging with intraoperative context soft lesions well. The setup operating room these procedures is also depicted. Conclusion: procedures, use an exoscope, addition well-known advantages terms magnification ergonomics, provides large space movement around field, greater ease devices ultrasound. minimal invasiveness approach no way hindrance exoscopic visualization dissection.
