Posterior reduction and internal fixation with posterior cranial fossa cranioectomy decompression for Chiari malformation type Ⅰ with basilar invagination, atlantoaxial subluxation, and syringomyelia

Chinese Journal of Contemporary Neurology and Neurosurgery, 2012
Background Chiari malformation type Ⅰ(CM⁃Ⅰ) is one of the soft tissue anomalies in craniovertebral junction (CVJ). This kind of soft tissue anomaly usually develops with bone anomaly, such as atlantoaxial subluxation, basilar invagination, platybasia, C1

Endonasal Odontoidectomy in Basilar Invagination. [PDF]

J Neurol Surg B Skull Base, 2021
Abstract Objective The endoscopic endonasal odontoidectomy (EEO) is emerging as a feasible surgical alternative to conventional microscopic transoral approach. In this article, we show EEO in the basilar invagination (BI) and describe in detail the technical aspects, advantages, and disadvantages of this approach (Fig. 1).

Basilar Invagination

Neurosurgery, 2010
Basilar invagination is a developmental anomaly of the craniovertebral junction in which the odontoid abnormally prolapses into the foramen magnum. It is often associated with other osseous anomalies of the craniovertebral junction, including atlanto-occipital assimilation, incomplete ring of C1, and hypoplasia of the basiocciput, occipital condyles ...
