BACKGROUND Pituitary adenoma, craniopharyngioma and meningioma are common sellar lesions, accounting for more than 90% of sellar tumors. The aim of this study is to assess the reliability and safety of the lateral supraorbital (LSO) approach to remove sellar tumors. METHODS Between June 2011 and December 2011, 23 patients with neoplastic lesions underwent surgery by the corresponding author (...

OBJECTIVE Endoscopic transsphenoidal approach has become the gold standard for surgical treatment of treating pituitary adenomas or other lesions in that area. Opening of bony skull base has been performed with burrs, chisels, and hammers or standard instruments like punches and circular top knives. The creation of primary bone flaps-as in external craniotomies-is difficult.The piezoelectric os...

Endoscopic endonasal approach (EEA) is expected to be ideal for the paramedian ventral skull base meningiomas, allowing wide access to the ventral skull base regions and realizing early devascularization of the tumor without retraction of the brain. We searched clinical reports of EEA for skull base meningiomas, written in English language, published before October 2014, using the PubMed litera...

BACKGROUND Approximately 60% of meningiomas are associated with peritumoral edema. Various causative factors have been discussed in the literature. The objective of this study was to investigate the correlation of PTBE with clinical, radiologic, and surgical aspects and recurrence of meningiomas. METHODS Sixty-one patients with benign meningiomas were chosen for surgical treatment by the Grou...

Background: The large and giant skull base meningiomas are challenging lesions, and the involvement of crucial neurovascular structures needs the surgical removal as the primordial treatment. The authors report on a series of patients with large and giant skull base meningiomas who were treated with the goal of radical removal. Methods: A retrospective study including 49 patients with large and...

Copyright © 2009 by the Congress of Neurological Surgeons Extended endoscopic endonasal approaches are becoming increasingly applied in the management of various intracranial pathol ogies along the midline cranial base. On one end of the complexity spectrum lie lesions such as pituitary adenomas and encephaloceles of the cribriform plate, which can be more easily approached through the endonasa...

AIM To visualize cranial nerves (CNs) using diffusion tensor imaging (DTI) with special parameters. This study also involved the evaluation of preoperative estimates and intraoperative confirmation of the relationship between nerves and tumor by verifying the accuracy of visualization. MATERIAL AND METHODS 3T magnetic resonance imaging scans including 3D-FSPGR, FIESTA, and DTI were used to co...

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 pe...

BACKGROUND Tuberculum sellae meningiomas (TSMs) present a special symptom because of the adherence and compression to the optic nerve, optic artery, and the chiasm. A significant number of patients with TSMs appear visual deficits. This study aimed to investigate the surgical indications of exploring the optic canal and visual prognostic factors in the neurosurgical treatment of TSMs. METHODS...
