CONTEXT It is unclear whether endoscopic transsphenoidal surgery (ETSS) or microsurgical transsphenoidal surgery (MTS) is a superior surgical approach for pituitary adenomas. OBJECTIVE The objective of the study was to compare the outcome of surgery with ETSS and MTS by experienced pituitary surgeons using criteria of remission using current consensus(More)
OBJECT Atypical (WHO Grade II) meningiomas comprise a heterogeneous group of tumors, with histopathology delineated under the guidance of the WHO and a spectrum of clinical outcomes. The role of postoperative radiotherapy for patients with atypical meningiomas who have undergone gross-total resection (GTR) remains unclear. In this paper, the authors sought(More)
OBJECT Endoscopic transsphenoidal surgery is expanding in acceptance, yet postoperative CSF leak rates remain a concern. This study presents the Cornell closure protocol, which has yielded significantly lower postoperative CSF leak rates compared with prior reports, as an algorithm that can be used by centers having difficulty with CSF leak. METHODS A(More)
OBJECTIVE To assess the advantages and limitations of the endoscopic endonasal approach to anterior skull base meningiomas, a minimally invasive approach that avoids extensive bone drilling, brain retraction, and manipulation of nerves and critical vessels, versus open transcranial surgery. METHODS A MEDLINE (2000-2010) search was performed to identify(More)
Giant (>4 cm) pituitary macroadenomas often require surgery to decompress the optic nerves. Compared with traditional open or transsphenoidal microscopic methods, the extended endoscopic endonasal transsphenoidal approach offers the potential for aggressive resection via a minimal access corridor. We conducted a systematic review of the literature to(More)
The International Subarachnoid Trial (ISAT), the largest prospective randomized study into endovascular and neurosurgical treatment of ruptured intracranial aneurysms, recently reported long-term follow-up in >The Lancet Neurology. In this cohort, the risk of death at 5 years was significantly lower in the coiled group, but the proportion of survivors who(More)
OBJECT As endovascular techniques have become more advanced, preoperative embolization has become an increasingly used intervention in the management of meningiomas. To date, however, no consensus has been reached on the use of this technique. To clarify the role of preoperative embolization in the management of meningiomas, the authors conducted a(More)
BACKGROUND AND PURPOSE Preoperative embolization for intracranial meningiomas offers potential advantages for safer and more effective surgery. However, this treatment strategy has not been examined in a large comparative series. The purpose of this study was to review our experience using preoperative embolization to understand the efficacy, technical(More)
Rathke's cleft cyst (RCC) is a rare lesion of the pituitary gland that is often asymptomatic. The objective of this study was to further characterise the presenting symptoms, endocrinopathy and potential for recurrence of this lesion in an Australian population. The files of 12 patients with pathologically confirmed RCCs were reviewed retrospectively.(More)
OBJECTIVE The risk for early and late seizures after aneurysmal subarachnoid hemorrhage (aSAH), as well as the effect of antiepileptic drug (AED) prophylaxis and the influence of treatment modality, remain unclear. We conducted a systematic review of case series and randomized trials in the hope of furthering our understanding of the risk of seizures after(More)
