Abstract Background Odontoidectomy may represent the treatment of choice for symptomatic ventral craniovertebral junction stenosis in selected cases. An endoscopic transnasal approach has been proposed as an alternative to a classic transoral approach. Method We report a case of a patient with a craniovertebral junction stenosis due to the ossification of the posterior ligament. The clinical and radiological records of the patient and a step-by-step description of the surgical technique are presented (Fig. 1). Conclusion Endoscopic transnasal odontoidectomy provides a direct access to the dens and adjacent structures of the anterior upper cervical spine with a less invasive burden on the oropharingeal structures.The link to the video can be found at: https://youtu.be/Ofrk1sFTV9I.

Abstract BACKGROUND Chordomas are primarily malignant tumors encountered at either end of the neural axis; the craniovertebral junction and the sacrococcygeal junction. In this article, we discuss the surgical management of craniovertebral junction chordomas. OBJECTIVE In this paper, we discuss the surgical management of craniovertebral junction chordomas. RESULTS The following approaches are illustrated: transoral-transpalatopharyngeal approach, high anterior cervical retropharyngeal approach, endoscopic transoral approach, and endoscopic transnasal approach. No single operative approach can be used for all craniovertebral chordomas. Therefore, the location of the tumor dictates which approach or approaches should be used.

Abstract For the past 20 years, the transoral approach to the upper cervical spine has been utilized for odontoid fractures, the removal of an abnormal odontoid process, decompression of basilar impression, and biopsy or resection of nasopharyngeal or metastatic tumors. The effectiveness and safety of this procedure is well documented. Use of the surgical microscope adds to the efficiency and safety of the procedure. We are reporting a case of fusion of the odontoid base to the anterior arch of the atlas. To our knowledge, this entity has not been described previously. The spinal cord was protected by an initial posterior fusion of C-1, C-2, followed in 10 days by a tracheostomy and the transoral removal of the anterior C-1 arch and the abnormal dens. Because the medical history did not reveal a source of trauma, it is supposed that the patient had malunion of the odontoid process to C-2, with subsequent migration and fusion of the dens to the C-1 arch.

Cervical Chordoma

Chordomas are rare tumors that arise from the sacrum, spine, and skull base. Surgical management of these tumors can be difficult, given their locally destructive behavior and predilection for growing near delicate and critical structures. En bloc resection with negative margins can be difficult to perform without damaging adjacent structures and causing significant clinical morbidity. For chordomas of the upper cervical spine, surgical options traditionally involve transoral or submandibular approaches. The authors report the use of the image-guided, endoscopic, transcervical approach to the upper cervical spine as an alternative to traditional techniques for addressing upper cervical spine tumors, particularly for tumors where gross-total resection is not feasible.

Microsurgical Techniques

abstract Three patients with chordomas of the clivus and the upper cervical spine underwent the removal of their tumors through a transoral approach with labiomandibular splitting and microsurgical techniques. This surgical approach provided excellent visualization of the anterior craniocervical area and allowed a gross total removal in each case. Although the lesions in our patients were chordomas, this approach could also be used for other surgical lesions in this area.
