Traumatic cervical spinal cord injuries (SCIs) can be lethal and are especially dangerous for older adults. Falls from standing and risk factors for a cervical fracture and spinal cord injury increase with age. This study estimates the 1-year mortality for patients with a cervical fracture and resultant SCI and compares the mortality rate with that from an isolated cervical fracture. ⋯ Using well-adjusted population-level data in older adults, this study estimates the 1-year mortality after SCI in older adults to be 36.5%. The mortality after a cervical fracture with SCI was 5 percentage points higher than in patients without SCI, and this difference is smaller than one might expect, likely representing the frailty of this population and unmeasured covariates.

Suprasellar arachnoid cysts are a rare but important pediatric neurosurgical pathology with unknown ideal management. They have been previously managed with techniques including open craniotomy with microsurgical fenestration, cystoperitoneal shunting, endoscopic ventriculocystostomy, and endoscopic ventriculocystocisternostomy (VCC), without a consistent consensus on the best surgical approach. We present an overview of the literature on surgical management of suprasellar arachnoid cysts. ⋯ This study examines the current literature on suprasellar arachnoid cyst surgical management to conclude that an endoscopic approach in comparison with other approaches has the best outcomes. Of the endoscopic options available, VCC provides patients with the best long-term resolution of symptoms and the lowest need for revision. These findings should be further investigated with larger multicenter studies to further compare different surgical techniques and outcomes.

Comparative Study
Minimally Invasive Approaches to the Lateral Cavernous Sinus and Meckel's Cave: Comparison of Transorbital and Subtemporal Endoscopic Techniques.
Transorbital and subtemporal keyhole approaches have recently been proposed to approach lesions in the lateral wall of the cavernous sinus (CS) and Meckel's cave (MC). Our goal was to compare these approaches and suggest indications for each of them. ⋯ LTOA is a good option to biopsy a lesion in the lateral wall of the CS and LOWA increased the surgical corridor to work with microsurgical techniques. STA and STZA could be better options when wide exposure is necessary, but temporal lobe retraction should be taken into consideration.

Identifying the histopathological diagnosis of a spinal tumor is the necessary step prior to pursuing subsequent treatment. Both minimally invasive and open spinal procedures have been described as useful methods of obtaining tumor tissue for diagnosis but differ by their limitations. Minimally invasive techniques, such as computed tomography-guided biopsies, can expose the patient to radiation, and the tissue obtained may be nondiagnostic. Tubular and open procedures require collateral soft-tissue damage and may require bony removal leading to iatrogenic injury. Endoscopic approaches to the spine can be employed to avoid treatment delay in diagnosis, decrease length of stay, and provide adequate tissue for diagnosis. ⋯ We demonstrate the application of an endoscopic transforaminal approach in spine oncology. We also describe our technique on how we use a beveled working channel to obtain a large tissue core sample for definitive diagnosis.

Hyperplasia of the choroid plexus represents a rare cause of communicating hydrocephalus in children. Recent work has associated such disease with genetic abnormalities (such as perturbations in chromosome 9). Given such extensive cerebrospinal fluid (CSF) overproduction, patients with choroid plexus hyperplasia often fail CSF diversion and therefore require adjuvant interventions. ⋯ The child was treated with an endoscopic third ventriculostomy and choroid plexus coagulation; however, he still required CSF diversion via a ventriculoatrial shunt. A genetic workup showed tetraploidy of chromosome 9. We discuss criteria for selection of treatment strategies, including endoscopic third ventriculostomy with choroid plexus coagulation and/or CSF diversion, that may prevent the need for re-operation in select patients with hydrocephalus due to choroid plexus hyperplasia.
