Transclival transcervical approach to the upper cervical spine and clivus.

The transclival-transcervical approach to lesions of the craniocervical junction is described. It gives reasonable access to the lower part of the clivus and to C1 and C2 for removal to tumours and stabilization of fractures and otherwise caused dislocations of this region. Because an opening of the pharynx can be avoided, reconstruction work can be done using bone graft or reinforced methyl-methacrylate without risk of infectious contamination. The results obtained in 6 cases are presented.
