INTRODUCTION: Endoscopic endonasal transsphenoidal surgery (EETS) is increasingly applied to treat tuberculum sellae meningiomas. However, if the tumor adheres firmly to the optic nerve, dissection of the interface between both structures should be prudent to preserve visual function. The purpose of this study was to investigate whether tumor adhesion to the optic nerve can be predicted preoperatively by fast imaging with steady-state acquisition (FIESTA). METHODS: Twenty-two patients with tuberculum sellae meningioma treated with EETS were retrospectively identified...

OBJECTIVE In tuberculum sellae meningioma (TSM) surgery, endonasal approaches are claimed to have a superior visual outcome compared with transcranial approaches. The authors question whether this is always true and analyze their series of cases of endoscope-assisted transcranial TSM surgery with special regard to the postoperative visual outcome in order to explore this issue. METHODS All surgical procedures for TSM performed between 2003 and 2015 in the Department of Neurosurgery, University Medicine Greifswald, were retrospectively analyzed...

The utility of nonmetric dental traits in population phenetic studies is well documented. However, consistency in scoring trait expression is a concern due to the subjectivity in scoring quasicontinuous variables with graded scales. The aims of this study are to 1) analyze intraobserver results from an independent scorer and 2) interpret the least precise results. Six hundred individuals (300 of each sex) were scored for 48 dental nonmetric traits using ASUDAS, in one preliminary (100 individuals) and two full observations...

γ-Aminobutyric acid (GABA) is a major amino acid neurotransmitter in the vertebrate brain. To provide detailed information on the distribution of the GABA in zebrafish (Danio rerio), neurons were labeled with mCherry driven by the glutamic acid decarboxylase 67 (gad67) promoter. In the transgenic line Tg(gad67:mCherry), mCherry-positive gad67 cell bodies were predominantly localized to the olfactory bulb, pallial zones, subpallium zones, parvocellular preoptic nucleus, periventricular gray zone of optic tectum, torus semicircularis, posterior tuberculum, medial longitudinal fascicle, caudal zone of periventricular hypothalamus, and oculomotor nucleus...

OBJECTIVE Planum sphenoidale (PS) and tuberculum sellae (TS) meningiomas cause visual symptoms due to compression of the optic chiasm. The treatment of choice is surgical removal with the goal of improving vision and achieving complete tumor removal. Two options exist to remove these tumors: the transcranial approach (TCA) and the endonasal endoscopic approach (EEA). Significant controversy exists regarding which approach provides the best results and whether there is a subset of patients for whom an EEA may be more suitable...

BACKGROUND: Resection of extensive skull base lesions often necessitates relatively large dural openings and arachnoid, resulting in skull base defects with the potential for a postoperative cerebrospinal fluid leak. A nasoseptal flap (NSF) is a vascularized graft that has greatly diminished the incidence of cerebrospinal fluid leak. Annealing of flaps against the ventral skull base can be tenuous within the first few days after surgery. We report the use of sphenoid sinus fat packing as a buttress to support the nasoseptal flap during skull base reconstruction...

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...
