Objective To explore the diagnosis and treatment of the instability of craniocervical junction after odentoidectomy. Method The clinical and imaging data of 8 patients, who suffered from the instability of the craniocervical junction after the odontoi-dectomy, were analyzed retrospectively. Results Seven patients with instability of craniocervical junction, who underwent operations of suboccipital decompression and occipitocervical fixation or bone grafting occipitocervical fusion, achieved satisfactory effect. There are no operative complications and death in all the patients. One patient with instability of craniocervical junction did not receive the operation. Conclusion The patients who suffered from postodontoidectomical instability of craniocervical junction can be treated by suboccipital decompression and occipitocervical fusion.
