Abstract An experience with 19 cases of transoral exposure of the lower clivus and ventral aspect of the upper cervical spine is presented. The spectrum of pathological entities in this series includes malformative, neoplastic, and spondylotic conditions. The report is designed to focus upon some points of overall surgical management of patients treated by the transoral approach, with emphasis on management of postoperative instability, and to underline the discrepancy in the prognosis of congenital and acquired disorders, in terms of mortality, morbidity, and long-term results.

The rotation stress test is used to evaluate stability of the craniocervical junction by assuming that it gives the maximum rotation. However, a more complex manipulation might show a higher rotation: the rotation with extension and contralateral bending. This was tested in vitro with ten upper cervical spine specimens.

AbstractBackground:Calcium pyrophosphate dihydrate deposition in the cervical spine is infrequently symptomatic. This is especially true at the craniocervical junction and upper cervical spine.Case Report:A 70-year-old previously healthy woman presented with a progressive cervical myelopathy of four months duration.Results:Examination revealed sensorimotor findings consistent with an upper cervical myelopathy. Radiological studies (plain radiographs, computed tomography, and magnetic resonance imaging) revealed C1-2 instability, and a well-defined extradural 3cm x 1cm retro-odontoid mass causing spinal cord compression. Transoral resection of the mass was performed followed by posterior C1-2 stabilization. Histological examination of the mass confirmed calcium pyrophosphate dihydrate deposition. Follow-up examination showed marked clinical and radiological improvement.Conclusion:Although uncommon, calcium pyrophosphate dihydrate deposition disease should be considered in the differential diagnosis of extradural mass lesions in the region of the odontoid.
