How I do it? Cranial setup for cranial settling
- 169 Downloads
Expanded endonasal endoscopic techniques allow us to treat several pathologies related to the odontoid process and craniocervical junction. Cases such as giant basilar invagination represent a surgical challenge.
The authors provide technical nuances and describe how to complete an endoscopic endonasal odontoidectomy and release the craniocervical junction with the aim of restoring a correct sagittal balance in cases with giant basilar invagination. The study of cadaveric specimens adds clarifying dissections.
Endonasal endoscopic odontoidectomy and craniocervical junction joint release allow the treatment of irreducible basilar invagination and restoration of better sagittal balance before posterior cervical occipitocervical fusion.
