Abstract
Objective To investigate the treatment of invagination with clivus-dens axis type in base of skull. Methods The clinical materials in 11 cases of invagination with clivus-dens axis type in base of skull were analyzed. All of them were treated by odontoidectomy via oral approach, and 10 of them were performed by occipito-cervical fusion. Results The mean follow-up was 1.2 years for all 11 patients. Remarkable improvement was achieved in 7 patients, improvement in 3, no change in 1, and no deterioration and death. Conclusions The treatment of invagination with clivus-dens axis type in base of skull by odontoidectomy via oral approach should be first considered, and occipito-cervical fusion should be performed for the patients with atlanto-axial dislocation.
