AIM This study aimed to assess the efficacy of endoscopic endonasal surgery, conducted by a team of neurosurgeons and otolaryngologists. MATERIAL AND METHODS We studied 40 patients who were undergoing surgery for primary non-functional pituitary adenomas with Knosp grades 1 to 3, at Keio University Hospital between 2005 and 2012. We compared the endoscopic endonasal transsphenoidal approach (...

Copyright © 2009 by the Congress of Neurological Surgeons Initially described by Schloffer (21) and Cushing (9) and subsequently popularized by Guiot (12) and Hardy and Wigser (14), the transsphenoidal approach to the sella now represents the preferred approach for removing pituitary adenomas. Traditionally performed with a microscope and a sublabial incision, the implementation of the endoscop...

In this study, we analyze and discuss the treatments of postoperative nasal complications after endonasal transsphenoidal resection of pituitary neoplasms (PNs). We performed 129 endonasal transsphenoidal resections of PNs and analyzed and treated cases with nasal complications. After endonasal transsphenoidal resection of PNs, there were 26 cases of postoperative nasal complications (20.1%), i...

Background Bioabsorbable plates are frequently utilized in the repair of skull base defects following transsphenoidal operations. Traumatic intracranial pseudoaneurysms are a rare complication of transsphenoidal surgery. To date, iatrogenic carotid pseudoaneurysm associated with the use of an absorbable plate has been reported once. Results A 57-year-old man with a large nonfunctional pituitary...

Background & Aim: Pituitary adenomas are part of a dissimilar group of benign neoplasms. The development of endoscopic techniques for surgery of paranasal sinuses has increased the opportunity for an endoscopic approach with regard to the pituitary gland. Minimally invasive endoscopic pituitary surgery, in turn, permits a more thorough tumor resection and fewer associated surgical complications...

INTRODUCTION Endoscopic endonasal transsphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. In many centers throughout the world, this technique is now routinely used for the same indications as conventional microsurgical technique for pituitary tumors. OBJECTIVE To present a surgical experience of consecutive endoscopic endonasal trans-sphenoidal resect...

Hemangioblastoma in the suprasellar region is rare. We present a case of a suprasellar hemangioblastoma that underwent surgical resection using an extended endoscopic transsphenoidal approach. A 64-year-old female patient presented with headache and decreased visual acuity for the last four years, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a 2.5 cm irregular lesion i...
