The utilization of cranial models created using rapid prototyping techniques in the development of models for navigation training

J Neurol Surg A Cent Eur Neurosurg, 2014 Jan;75(1):12-5.

Navigation in neurosurgery has expanded rapidly; however, suitable models to train end users to use the myriad software and hardware that come with these systems are lacking. Utilizing three-dimensional (3D) industrial rapid prototyping processes, we have been able to create models using actual computed tomography (CT) data from patients with pathology and use these models to simulate a variety of commonly performed neurosurgical procedures with navigation systems.

Transfrontal Transaqueductal, Transtrigonal, and Suboccipital Infratentorial Supracerebellar Endoscopic Fenestration of Posterior Fossa Arachnoid Cysts: Three Surgical Cases

J Neurol Surg A Cent Eur Neurosurg, 2017 Mar;78(2):210-215.

Symptomatic intracranial arachnoid cysts are commonly treated using neuroendoscopy. Cysts located within the posterior fossa may present a greater surgical challenge to the neurosurgeon due to the numerous vital neurovascular structures located within this confined space. Adding neuronavigation during endoscopy helps a neurosurgeon to visualize and utilize both anterior and posterior corridors safely to access and manage these lesions. We present three symptomatic posterior fossa arachnoid cysts that were treated successfully using minimally invasive neuronavigation-guided endoscopic neurosurgery utilizing the anterior transfrontal transaqueductal, anterior transfrontal transtrigonal, and posterior suboccipital infratentorial supracerebellar approaches.

BACKGROUND: Pituitary apoplexy is an acute clinical syndrome constituted by headache, visual impairment, ophthalmoplegia, and altered mental status. Abducens nerve palsy due to pituitary apoplexy is a significant clinical manifestation in pituitary apoplexy cases.This study aims to investigate the rare occurrence of isolated sixth cranial nerve palsy in patients with pituitary apoplexy, a condition characterized by sudden hemorrhagic or ischemic infarction of the pituitary gland.

METHODS: A search was conducted on major databases, including PubMed, Web of Science, and ScienceDirect, to identify cases of isolated sixth cranial nerve palsy in patients with pituitary apoplexy. Only six cases were found in the available literature. Descriptive statistics were used to summarize the data, and relevant clinical features were compared between the cases.

RESULTS: Among the six identified cases, isolated sixth cranial nerve palsy in patients with pituitary apoplexy predominantly affected middle-aged adults, with a prominent male preponderance. Clinical manifestations included acute-onset diplopia and headache, with the most common radiologic finding being pituitary gland enlargement or hemorrhage. Laboratory investigations revealed hormonal dysregulation in some cases. Treatment approaches varied and included conservative management and surgical intervention. Outcomes were generally favorable, with most patients experiencing partial or complete resolution of their cranial nerve palsy.

CONCLUSION: Isolated sixth cranial nerve palsy in patients in the context of pituitary apoplexy is an exceptionally rare occurrence, with only six documented cases in the available literature. Further research and case reporting are essential to better understand this rare clinical entity and guide optimal management strategies.
