OBJECTIVES/HYPOTHESIS
The aim of this study was to characterize the anatomic relation of the craniovertebral junction (CVJ) relative to the palatal line (PL), determine if the height of the CVJ over the PL is directly related to the anterior skull base (ASB) angle and the condition of platybasia, and consider the impact of the findings on endoscopic surgical approaches to the skull base.
STUDY DESIGN
Retrospective radiographic review.
METHODS
A retrospective study was performed using patients with chronic rhinosinusitis (CRS) as the control population and patients with platybasia as the study population. Sagittal magnetic resonance imaging and computed tomography were used to measure the ASB angle and the height of the CVJ above or below the PL.
RESULTS
The height of the CVJ relative to the PL is significantly higher in the platybasia group compared to the CRS group. However, a linear relationship is not identified between ASB angle and height of the CVJ relative to the PL. The height of the CVJ relative to the PL shows a wide distribution in both populations extending >1 cm above (platybasia group) and 1 cm below (control group).
CONCLUSIONS
Platybasia results in a higher CVJ relative to the PL compared to the general population; however, the relationship is not linear. The wide distribution of the CVJ relative to the PL indicates that the approach selection must be tailored to the patient's specific anatomy.

Review
BACKGROUND
The cervical spine is one of the main sites of manifestation in rheumatoid arthritis outside of the extremities. It can have a decisive influence on disease course via the occurrence of mechanical instabilities as well as neurologic symptoms. Both adequate diagnosis and the corresponding surgical treatment represent a challenge for the involved physicians.
MATERIALS AND METHODS
This review presents relevant diagnostic strategies and possibilities for surgical intervention which aim to avoid potentially fatal neurologic symptoms. Basic literature and expert opinions are also discussed.
RESULTS AND CONCLUSION
Through target-oriented surgical management, as well as tight clinical and radiologic monitoring during conservative and surgical therapy, potentially fatal disease courses can be avoided.

INTRODUCTION
The vascular compression of a nerve is known to be the most important cause of idiopathic trigeminal neuralgia (ITN) by most authors. However, several cases of skull base deformities in patients with ITN have been reported in our bibliographic review. AIM. To compare the existence of platybasia between a group of patients with ITN and a randomized control group.
SUBJECTS AND METHODS
Twenty-five patients with ITN and twenty-five control subjects were X-rayed and their basal angles were measured and compared.
RESULTS
The basal angle measured to investigate the existence of platybasia is significantly greater in the ITN group than in the control group. Platybasia was found in 10 patients with ITN. However, only two cases of platybasia were reported in the control group. Therefore in our study we have found that the incidence of platybasia in patients with ITN is significantly increased.
CONCLUSION
Our data demonstrated that platybasia has an important role in the pathogenesis of the ITN by altering the normal anatomy of the nerves and vessels within the posterior fossa.

A case is presented of a 35-year-old woman diagnosed with platybasia associated with Klippel-Feil syndrome type I. She was admitted to University Department of Neurology for clinical examination because of walking difficulties, dizziness, and intermittent vision disturbances. Neurological examination revealed a predominance of cerebellar symptomatology. Relevant diagnostic work-up included craniogram, cervical spine x-ray, computed tomography (CT) of the brain and craniocervical junction, magnetic resonance imaging of the brain, electroencephalography, ophthalmologic examination, urinary tract ultrasonography, laboratory tests, and psychological testing. CT of the craniocervical junction showed platybasia, congenital fusion of the second and third cervical vertebrae, and basilar invagination of dens axis. Platybasia is leveling of the angle between the floor of the anterior cranial fossa and posterior cranial fossa in the area of sella turcica, which is normally at 115-140 degrees. Basilar impression or invagination is moving up of the basis of the occiput and occipital condyles into the cranium, which means that the borders of the foramen magnum, condyles and adjacent bone are invaginated into the posterior fossa. Klippel-Feil syndrome type II is massive fusion of two of seven cervical vertebrae associated with short neck and low hair line.
