Background While effective for the repair of large skull base defects, the Hadad-Bassagasteguy nasoseptal flap increases operative time and can result in a several-week period of postoperative crusting during re-mucosalization of the denuded nasal septum. Endoscopic transsphenoidal surgery for pituitary adenoma resection is generally not associated with large dural defects and high-flow cerebro...

The hypothalamic-pituitary axis is recognized to an increasing extent as a physiological unit which influences and is influenced by endocrine and autonomic function. Anatomically, however, a clear distinction is to be drawn, with regard to both cellular and vascular anatomy, betweenthe neural (hypothalamus and neurohypophysis) and the glandular epithelial (pars distalis) components of the axis....

Empty sel la refers to the radiological appearance of an enlarged or deformed sella turcica that is partially or completely filled with cerebrospinal fluid. In the earlier days, the radiographic appearance of an enlarged sella turcica was frequently equated with the presence of an intra or perisellar neoplasm. It was found, however, in some of these patients on pneumoencephalography, that the e...

BACKGROUND Primary empty sella is a herniation of the sellar diaphragm into the pituitary space. It is an incidental finding and patients may manifest neurological, ophthalmological and/or endocrine disorders. Episodes of vertigo, dizziness, and hearing loss, have been reported. OBJECTIVE To determine the conditional probability, as well as the statistical dependency, through the Bayesian ana...

AIM Tuberculum sellae meningiomas (TSMs) are suprasellar lesions that commonly extend to the medial side of the optic nerve, resulting in visual impairments in the affected eye as the initial and most common symptoms. The primary goal of surgical treatment for TSM is the preservation or improvement of visual function. The aim of the present study was to assess the clinical outcomes of TSMs trea...

Dipsacaceae (Dipsacales) contains ca. 300 species of perennial and annual herbs and shrubs that occur primarily in the Mediterranean Basin, with about 20% distributed in Asia and Africa. Members of Dipsacaceae occur in open and relatively dry habitats from sea level to highalpine altitudes, with the exception of a few species that occupy moist meadow habitats. Like other Dipsacales, members of ...

Tuberculum Sellae Meningioma (TSM) is one of the most challenging operations among neurosurgeons. Many approaches have been proposed in the attempt of total removal of the tumor. Rhabdoid meningioma is a rare subtype of meningiomas accounting for 2-3% of all intra-cranial meningiomas, an aggressive tumor classified as World Health Organization (WHO) grade III; it occurs mainly in the early chil...

AIM Fibrous dysplasia is a benign disease in which medullary bone is replaced by fibro-osseous tissue, and causes distortion and overgrowth of the involved bone and represents about 3% of all bone tumors. There is variability in the manifestation of Fibrous Dysplasia lesions with imaging techniques due to their proportional variations of fibrous to osseous tissue. Radiological d...
