INTRODUCTION: With the advent of skull base endoscopy, tuberculum sellae meningiomas (TSMs) are currently operated both from the traditional transcranial (TC) route as well as the extended endonasal endoscopic trasnssphenoidal approach (EETS). The aim of this study was to conduct a systematic review of TSMs excised via the TC route in the modern era when the EETS excision is gaining popularity. EVIDENCE ACQUISITION: We performed a systematic review in the medical literature following the PRISMA guidelines...

PURPOSE: To determine the relationship of the medial meniscus with the infrapatellar branches of the saphenous nerve, the primary goal is to define and characterize different risk areas for these nerves during medial meniscus surgery. METHODS: After dissecting 20 embalmed cadaver knees, we defined 7 readily identifiable anatomical landmarks. For each knee, we recorded 2 morphological criteria and 16 measurements. RESULTS: The most common anatomical course is a main trunk that is 8 mm anterior to the tuberculum adductorium and 60 mm posterior to the midpoint of the medial patellar margin...

Tuberculum sella and planum sphenoidale meningiomas pose a management challenge given their intimate relationship to surrounding critical neurovascular structures. The development and advancement of expanded endoscopic transnasal surgery has provided a good surgical option that in well-selected cases, may provide several advantages over a transcranial route. These include early devascularization, complete dura and bone removal, elimination of brain retraction and enhanced visualization of the optic apparatus perforating vessels...

Preservation of the optic nerves is an important issue in the resection of tuberculum sellae meningiomas. We report the case of a patient whose optic nerve was penetrated by a tuberculum sellae meningioma. During surgery, a bulging tumor was found to penetrate the right optic nerve. The tumor was gross totally removed, including tumors bulging through the optic nerve. Two trunks of the split optic nerve were preserved. The penetrated shape of the optic nerve may lead to misjudgment and its damage. Divided trunks of optic nerves are difficult to recognize and may be confused for the tumor capsule, because they may be thinned and seem to contain tumors...

The introduction of modern endoscopy in neurosurgery brought light to one of the darkest areas: the skull base. In particular, the trans-nasal route allowed skull base surgeons to visualize and dominate the entire midline skull base. We analyzed our surgical series of 199 patients that were affected by several pathologies (pituitary adenomas, clivalchordomas, craniopharyngioma, Rathke's cleft cysts, tuberculum sellaemeningiomas, and craniovertebral junction pathologies with bulbar compression) and treated each by using a 3D-HD endoscope between December 2012 and December 2015 and reviewed the literature...

AIM: Reconstruction technique advances have created renewed enthusiasm for the expanded endonasal approach (EEA). However, as with any new technique, early experiences inevitably lead to more selective use of these techniques. We reviewed our experience of the expanded endonasal endoscopic approach for skull base meningiomas and place it in context of the literature. MATERIAL AND METHODS: We performed retrospective review of all endonasal cases performed at our center for histologically proven meningioma...

Brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family, has emerged as an active mediator in many essential functions in the central nervous system of mammals. BDNF plays significant roles in neurogenesis, neuronal maturation and/or synaptic plasticity and is involved in cognitive functions such as learning and memory. Despite the vast literature present in mammals, studies devoted to BDNF in the brain of other animal models are scarse. Zebrafish is a teleost fish widely known for developmental genetic studies and is emerging as model for translational neuroscience research...

INTRODUCTION: The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (contaminated cavity) and the subarachnoid space (sterile area), reducing the high risk of contamination. OBJECTIVE: To assess the otorhinolaryngologic complications in patients undergoing endoscopic surgery of the skull base, in which a nasoseptal flap was used...

Galanin is a multifunctional neuropeptide that is implicated in the modulation of physiological processes, including nociception, cognition, feeding behavior, neuronal growth, and reproduction. The physiological effects of galanin are mediated through its interaction with three different G protein-coupled receptors, i.e., GALR1, GALR2, and GALR3. Unlike mammals, zebrafish have four different receptors for galanin, diversified from GALR1 (GAL1a and GALR1b) and GALR2 (GALR2a and GALR2b). Despite the importance of galanin in the central nervous system (CNS), no information has been reported regarding GalR2 in zebrafish CNS...

OBJECTIVE Microsurgical resection of perisellar meningiomas has remained the gold standard for treatment, with extended endoscopic endonasal surgery emerging as a viable alternative. Historical microsurgical series do not distinguish based on tumor anatomy, but are being used as a comparison against endonasal surgery. In this study, the authors retrospectively reviewed and compared the anatomy of perisellar meningiomas seen at their institution. The tumors were separated into 2 groups based on whether they would be appropriate for endoscopic resection, and the authors compared the surgical outcomes...

BACKGROUND: The evolution of skull base surgery over the past decade has been influenced by advancement in visualization technology. Recently, as a result of such improvements, three-dimensional (3-D) scopes have been widely used during endoscopic endonasal approaches. In the present study, we describe the use of 3-D stereoscopic endoscope for the treatment of a variety of skull base lesions. METHODS: From January 2010 to June 2015, a 3-D endoscopic endonasal approach (4 and 4...

The habenulae are bilateral nuclei located in the dorsal diencephalon that are conserved across vertebrates. Here we describe the main afferents to the habenulae in larval and adult zebrafish. We observe afferents from the subpallium, nucleus rostrolateralis, posterior tuberculum, posterior hypothalamic lobe, median raphe; we also see asymmetric afferents from olfactory bulb to the right habenula, and from the parapineal to the left habenula. In addition, we find afferents from a ventrolateral telencephalic nucleus that neurochemical and hodological data identify as the ventral entopeduncular nucleus (vENT), confirming and extending observations of Amo et al...

Experiences acquired in our department with endoscope assisted microsurgical transsphenoidal pituitary surgery encouraged us to expanded the endoscopic approach to skull base lesions. The endoscopic endonasal transsphenoidal approach proved to be less traumatic to the traditional microsurgical approaches, yet very effective. The endoscopic transsphenoidal technique was applied in a patient havin anterior skull base tumor. The patient was a 49-year-old woman with several months history of left visual defect...

Optic canal invasion by tuberculum sellae meningiomas (TSMs) has been reported, but the characteristics of invasion remain unclear. This study was performed to clarify the incidence and characteristics of optic canal invasion by TSM and to determine whether optic canal invasion could be predicted preoperatively by magnetic resonance imaging (MRI). Between February 2002 and August 2014, 31 patients with TSM underwent tumor resection in our institute. In all cases, the optic canal was explored to identify any tumor invasion...
