Semisitting position for cerebello-pontine angle surgery: Analysis of complications and how to avoid it.

Objective: To analyze the primary complications related to semisitting position in patients undergoing cerebelo-pontine angle surgery.

Methods: Retrospective data analysis from patients undergoing elective tumoral cerebelo-pontine angle surgery in a semisitting position. The incidence, severity, occurrence moment, treatment, duration, and outcomes of venous air embolism (VAE), pneumocephalus, postural hypotension, and other complications were recorded.

Atypical facial pain after cranioplasty: A too perfect design?: Dolor facial atípico asociado a craneoplastia: ¿un encaje demasiado perfecto?

Cranioplasty is a procedure routinely performed in neurosurgery. It is associated with significant morbidity and several types of postsurgical complications. The most common are infections, bone flap resorption and hematomas.

Primary vertebral tumor of axis: A clinical and surgical challenge.

We report the case of a 17-year-old male presented to the emergency department with a six weeks history of neck pain and no neurogical deficit. Computed tomography and magnetic resonance imaging revealed an expansile lesion in the axis, with soft tissue and spinal cavity invasion, without mielopathy signs. Tomography-guided mass biopsy was taken.

[Progressive Brown-Sequard syndrome secondary to idiopathic spinal cord herniation: clinico-radiological and surgical correlations].

Introduction: Idiopathic medullary herniation is an infrequent disease, which shows up in clinical form as a progressive mielopathy, most commonly known as the Brown-Sequard syndrome. Its anatomical base is a dural defect where a portion of anterior spinal cord gets progressively incarcerated. The MRI and myelo-CT scan show a bending of the spinal cord in the form of a «bell tent» towards the anterior dural sheath at the mid-dorsal portion mainly.

Atlantoaxial subluxation secondary to retropharyngeal abcess in adults (Grisel's syndrome). Review of literature about a clinical case.

Grisel syndrome (GS) is a non-traumatic atlanto-axial subluxation produced after an inflammatory, infectious or postsurgical process of the upper neck region. It is a characteristic, although currently uncommon complication of acute bacterial pharyngitis in the pediatric age. Presentation in adults is even more infrequent and requires specific management.
