TRANSORAL REMOVAL OF SKULL BASE AND C1-C2 VERTEBRAL BODY TUMOURS AND NONTUMOROUS PATHOLOGY IN THE CRANIOCERVICAL JUNCTION ACCOMPANIED BY CRANIOVERTEBRAL INSTABILITY
2010
27 patients aged 2,5-61 years with skull base and C1-C2 vertebral body tumours and nontumorous pathology in the craniocervical junction underwent surgery. All patients revealed craniovertebral instability. To perform OSD we used autobone and metallic wire in 1 case, "Ventrofix" - 2; "CCD" - 9, "Vertex" - 15. In 26 cases OSD was followed by transoral tumor removal; in 1 - removal of the skull base chordoma spreading into C1-C2 segments was followed by OSD. In our practice we used original patent instruments, devices and surgical techniques. After the tumor has been removed, the skull defect hermetic closure and plasty were performed using the original patent technique for preventing postoperative CSF leakage as well as different glue compositions. This technique proved to shorten hospitalization period and reduce treatment costs as well as launch an early rehabilitation programme - on the 3d-4th day after operation. Use of new technologies in surgical treatment of skull base tumors invading upper cervical spinal segments accompanied by craniovertebral instability allowed to improve surgical outcome and start up early rehabilitation.
