All surgical approaches to the anterior skull base involve the olfactory cistern and have the risk of damaging the olfactory nerve. The purpose of this study was to describe the microanatomical features of the olfactory cistern and discuss its surgical relevance. In this study, the olfactory cisterns of 15 formalin-fixed adult cadaveric heads were dissected(More)
The aim of this study is to explore the association between the polymorphisms of galectin-3 gene and clinico-pathological characteristics and prognosis of gliomas. We enrolled 190 histologically diagnosed gliomas and 210 healthy controls in this study. Two genetic variants at galectin-3 single nucleotide polymorphism (SNP) sites (galectin-3 +191 A>C and(More)
Ectopic pituitary adenoma with an empty sella is extremely rare. We report an unusual patient with an ectopic growth hormone-secreting pituitary adenoma in the sphenoid sinus with an empty sella. The association is related to a development disorder of the anterior pituitary tissues. Tumor in the sphenoid sinus was completely removed by endoscopic endonasal(More)
AIM To investigate the variation and significance of malondialdehyde (MDA) and superoxide dismutase (SOD) in brain tissue after secondary brain injury (SBI) with seawater immersion in rats. MATERIAL AND METHODS We randomly divided 163 male Sprague Dawley rats into 4 groups, as normal (Group A), SBI (Group B), SBI with physiological saline immersion (Group(More)
BACKGROUND Neurosurgery in areas with restricted space and complicated anatomy can be greatly aided by the virtual reality (VR) technique. The clivus represents one of such challenging surgical areas, but its VR has not been established. The present study aimed to document a VR model of clival anatomy that may be useful in clival surgery. METHODS High(More)
BACKGROUND It is difficult for neurosurgeons to perceive the complex three-dimensional anatomical relationships in the sellar region. METHODS To investigate the value of using a virtual reality system for planning resection of sellar region tumors. The study included 60 patients with sellar tumors. All patients underwent computed tomography angiography,(More)
OBJECT Liliequist's membrane (LM) is an important arachnoid structure in the basal cisterns. The relevant anatomic descriptions of this membrane and how many leaves it has are still controversial. The existing anatomical theories do not satisfy the needs of minimally invasive neurosurgery. We aimed to establish the three-dimensional configuration of LM. (More)
OBJECT The aim of this report was to explore the clinical presentation, radiological features, treatment methods, and outcome of micro-AVMs presenting with intracerebral hemorrhage. METHODS The clinical data, radiological features, treatment, and follow-up results for a consecutive series of 13 cases with micro-AVMs were retrospectively analyzed. (More)
INTRODUCTION The aim was to investigate the relationship between the tumor (clinicopathologic and radiological) characteristics and the morphological parameters of pituitary macroadenoma or giant adenoma patients using a three-dimensional (3D) reconstructed model. MATERIAL AND METHODS Magnetic resoanance imaging (MRI) was performed preoperatively; tumor(More)
Microanatomical dissection was performed on 14 formalin-fixed human cadaveric head specimens to provide information relevant for surgical procedures involving the cistern of the lamina terminalis (LT). The cistern of the LT was located in the midline of the telencephalon and was tent-shaped. The superior wall was located between the septal areas(More)
