“…The transoral approach is an effective surgical procedure for the direct decompression of the ventral cervicomedullary junction. This approach has been recommended by many surgeons for extradural lesions, because it offers decompression between the midclivus and the upper cervical region [4,5,8,10,17]. The transoral approach for craniospinal malformations was first used by Kanavell and Le Fort in 1918 [11].…”

A neurosurgical view of anatomical evaluation of anterior C1–C2 for safer transoral odontoidectomy

An anatomical study for evaluation of anterior C1-C2. To provide essential anatomic data for safer transoral odontoidectomy. The surface dimensions of the atlas vertebra and the transoral approach for odontoidectomy have been described in detail. Anterior arcus of C1 must be drilled out to reach odontoid process for transoral odontoidectomy. The thickness of anterior ring of C1 has not been studied before. Sixty, dried adult atlas and 60 axis vertebrae and ten cadaveric craniocervical specimens were measured for the following: (1) bony drilling depth (BDD), the distance from the anterior wall of anterior ring of C1 to anterior wall of odontoid; (2) minimum drilling diameter (MDD), distance of minimum C1 anterior ring removal for odontoid resection on horizontal plane; (3) maximum bony drilling diameter (MBDD), distance of maximum C1 anterior ring removal for odontoid resection on horizontal plane. Lateral border of this diameter is limited by medial borders of the lateral mass; (4) the widest odontoid diameters (WOD) on coronal sections were measured. On 60 atlas and axis vertebrae, the BDD was 7.0 +/- 1.2 mm on dry bones, the distance between the medial borders of the lateral mass (MBDD) was 16.1 +/- 1.5 mm, and the WOD on coronal sections (WOD) was 9.8 +/- 0.8 mm. On cadavers, the distance between the two edges of C1 anterior ring removal for odontoid resection (MDD) was 10.8 +/- 1.1 mm and the WOD on coronal sections (WOD) was 10.1 +/- 1.4 mm. An odontoid surgery through transoral approach is safe and feasible. A quantitative understanding of the anterior anatomy of C-1 and C-2 is necessary when considering transoral odontoid resection. In this study the authors define safe zones for anterior atlas and axis.

“…Although chordoma does not grow rapidly, it is a tumor with rapid postoperative recurrence. Of all reported cases, only about 15% are located in the vertebral column [2,3]. The remaining 85% involve the sacrococcygeal area or spheno-occipital area.…”

Chordoma, which is a rare bone tumor, originates from the embryonic notochord. The most common sites are the spine and skull base. It is a low grade, but malignant tumor that is located mostly in the sacrococcygeal region of the spine. Involvement of the cervical, thoracic, and lumbar spine is an unusual site for chordoma in general neurosurgical practice, occurring in only 15% of cases. Surgery should be performed as the first treatment option. Even if the entire tumor has been resected, it frequently recurs locally. Distant metastases are uncommon. We present a 53-year-old woman with retropharyngeal C3, C4 and C5 mass. She presented with long-standing swallowing difficulty and neck pain. Surgery was performed with the anterior cervical approach and the final pathologic diagnosis was chordoma. We present the case with detailed clinical course, radiological findings, and pathological findings. Complete surgical resection is the first treatment option. Although it metastasizes less, local recurrence is common. In surgical treatment, gross total resection should be applied and radiotherapy should be given if residual is considered.

Two patients presented with congenital basilar invagination manifesting as progressive myelopathy. Both patients underwent surgery using a neuronavigation-assisted transoral-transpharyngeal approach. The Brain-LAB Vector Vision navigation system was used for image guidance. The registration accuracies were 0.9 and 1.3 mm. After decompression, posterior stabilization was performed. Both patients had an uneventful postoperative course. The transoral-transpharyngeal approach with the neuronavigation system provides safe exposure and decompression for basilar invagination.
