INTRODUCTION: Odontoidectomy can help decompress ventral compression of the brainstem and upper cervical spinal cord in the presence of bony abnormalities of the craniovertebral junction (CVJ), e.g., an odontoid pannus. Endonasal approaches have been shown to be associated with lower morbidity compared with traditional transoral approaches. We demonstrated an entirely endonasal approach to the CVJ. MATERIALS AND METHODS: We presented our technique for performing an endoscopic endonasal odontoidectomy...

BACKGROUND: Neurologic manifestations of craniovertebral junction (CVJ) disease may generate dramatic brainstem damage, which could evolve to paralysis. In most cases, patients are referred with advanced neurological symptoms such as tetraplegia/paresis. The aim of this study was to identify predictive factors of favorable neurological evolution after non-traumatic brainstem compression. METHODS: A prospective study evaluated 143 consecutive patients who had undergone CVJ anterior brainstem decompression...

BACKGROUND: Aberrant medial retropharyngeal prevertebral course of internal carotid arteries (ICAs) is extremely uncommon. In oropharyngeal surgeries like trans oral odontoidectomy (TOO) this unrecognized aberrant retropharyngeal course of ICAs can result in devastating complications secondary to inadvertent injury of ICAs. Authors describe this aberrant course of ICAs in a patient with craniovertebral junction (CVJ) anomaly with dysmorphic C1 lateral mass on one side and discuss in detail various management issues in this complex case...

Chiari malformations (CMs) are variant structural setup of cerebellum and brain stem at the craniovertebral junction. Normally the cerebellum and parts of the brain stem lie above the foramen magnum. When the part of the cerebellum and/or brainstem protrudes into the upper spinal canal through foramen magnum, it is defined as CM. Chiari malformations may develop when part of the skull is smaller than normal or misshapen, due to which the cerebellum herniates into spinal canal through foramen magnum. This compresses the cerebellum and brainstem affecting functions controlled by these parts and blocks the flow of cerebrospinal fluid that surrounds and cushions the brain and spinal cord...

Pathological processes in the craniovertebral region (CVR) are usually accompanied by dislocation complications leading to gross neurological disorders. One of the diseases that affect the CVR and lead to atlanto-axial dislocation (AAD) is rheumatoid arthritis. Errors in the diagnosis of rheumatoid disease and in the choice of a treatment approach may cause adverse outcomes. OBJECTIVE: To define the approach for surgical treatment of AAD associated with rheumatoid disease of the CVR, with allowance for the rigidity of deformity...

OBJECTIVE: Craniovertebral junctional anomalies constitute a technical challenge. Surgical opening of atlantoaxial joint region is a complex procedure especially in patients with nuchal deformity like basilar invagination. This region has actually very complicated anatomical and functional characteristics, including multiple joints providing extension, flexion, and wide rotation. In fact, it is also a bottleneck region where bones, neural structures, and blood vessels are located. Stabilization surgery regarding this region should consider the fact that the area exposes excessive and life-long stress due to complex movements and human posture...

Patients with craniovertebral junction anomalies are more likely to undergo craniovertebral junction procedures because of neurologic complications. Vertebral arteries (VAs) are more prone to injury in these cases because of an often anomalous course, with potentially disabling or grave sequel. In our patient with partially occipitalized atlas, CT angiogram revealed that 1 of the VAs passed through the bony canal in the occipitalized and/or fused bone, whereas the VA on unfused side was also unexpectedly anomalous and of C2 segmental type...

Our clinical experience led us to realize that craniovertebral junction (CVJ) abnormalities were common in surgical patients with congenital muscular torticollis (CMT). This study aimed to report the concurrence rate of CVJ abnormalities in surgical patients with CMT, along with comprehensive evaluation of type of concurrent CVJ abnormalities. This was a retrospective cohort study in a tertiary hospital, including 41 subjects who underwent surgical release for CMT at the mean age of 8.38 years. The presence of CVJ abnormalities was analyzed, using craniofacial 3-dimensional computed tomography images...

BACKGROUND: Atlantoaxial spondyloptosis (AAS), which is defined as complete displacement of facets of atlas anterior to the facets of axis such that there is no contact between the 2 articulating surfaces, is an extremely rare manifestation of atlantoaxial instability. The reason for an extreme rarity of traumatic AAS is probably the severity of injury in traumatic AAS that is usually incompatible to life. It represents the most severe form of atlantoaxial dislocation, and complete reduction in such a case presents a real technical challenge because of the interlocking of C1-C2 facets...

OBJECTIVE: For many years, the microsurgical transoral approach (TOA) has been accepted as the "gold standard" for the surgical treatment of a variety of congenital, developmental, and acquired pathologies affecting the craniovertebral junction. In the present study, we try to investigate both experimental and clinical fronts of such a challenging surgery, starting from the updated literature experience. TOA is actually presented as an "old-fashioned" surgical technique dealing with possible bacterial contamination, the need of postoperative nose gastric tube feeding for a week, the possible nasopharyngeal incompetence, and the postoperative tongue swelling...

BACKGROUND: The transoral approach provides the most direct exposure to extradural lesions of the ventral craniovertebral junction. The morbidity and mortality from this approach greatly limits its use because they are still feared and debated. Using univariable and multivariable logistic regression analyses, this study aims to identify the factors associated with short-term complications in patients undergoing the transoral approach. METHODS: A consecutive cohort analysis of prospectively collected data in several neurosurgery spine departments evaluated 143 consecutive patients who had undergone craniovertebral junction transoral approach surgery...

OBJECTIVE: A precise anatomical description of the alar ligaments is important to better understand their biomechanical and pathologic implications. Although there are several studies regarding their anatomy, the literature is inconsistent. To our knowledge, there are no reports that compare cadaveric morphologic findings with computed tomography (CT) images of the alar ligaments. METHODS: Eight sides from 4 fresh-frozen cadaveric specimens were used in this study...
