Figure 3: Illustration of a novel posterior approach to odontoidectomy in patients with basilar invagination. (a) The patient is positioned prone on the operating table, the head is fixed in a radiolucent carbon fiber clamp, midline marking is performed, and the neuronavigation system is installed, followed by the registration. (b) Computed tomography scanning is completed preoperatively to perform the image-guided procedure. Neuromonitoring modalities are also visible. (c) Bone removal of the odontoid process is initiated from the right side of the patient using the Cavitron ultrasonic surgical aspirator. (d) Odontoidectomy is continued with a bone-cutting device. (e) Location confirmation with the neuronavigation system provides safety during surgery. (f and g) Verifying the surgical trajectory with an endoscope further enhances security and confidence. (h) Completion of bone removal using punch forceps
