We describe a supra-diaphragmatic ectopic pituitary adenoma that was safely removed using the extended endoscopic endonasal approach, and discuss the value of three-dimensional (3D) endoscopy and intra-operative magnetic resonance imaging (MRI) to this type of procedure. A 61-year-old-man with bitemporal hemianopsia was referred to our hospital, where MRI revealed an enhanced suprasellar tumor ...

INTRODUCTION Dacryocystorhinostomy (DCR) is the treatment of choice for nasolacrimal duct obstruction. Although external DCR is regarded as the gold standard, endoscopic DCR is evolving as an equally-effective alternative. Objectives To compare the success rate of treating nasolacrimal duct obstruction by endoscopic endonasal method compared to the conventional DCR surgery. Materials and method...

BACKGROUND The choice of endoscopic expanded endonasal approach introduces the possibility of improved gross total resection of craniopharyngioma while minimizing surgical morbidity in a significant subset of patients. METHODS From our trans-sphenoidal surgical series of 331 cases, we retrospectively reviewed visual, endocrine and neuro-cognitive outcomes in the first consecutive eight patien...

OBJECTIVE We evaluated postoperative changes in nasal cavity volume and their effects on nasal function and symptoms after endoscopic endonasal transsphenoidal approach for antero-central skull base surgery. STUDY DESIGN Retrospective chart review at a tertiary referral center. METHODS We studied 92 patients who underwent binostril, four-hand, endoscopic endonasal transsphenoidal approach s...

Ossifying fibroma is a benign fibro-osseous tumour that rarely involves the ethmoid sinuses and orbit. It is classified as a benign fibroosseous lesion, a term that is synonymous with a variety of lesions reported in the literature. Recurrence rate with deleterious effects in cases of extramandibular ossifying fibroma is the impetus for open en bloc resection of the tumour. Continuously evolvin...

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...

OBJECTIVE To study anatomical structures related to Meckel cave with endonasal endoscopic approach and to provide an anatomical basis for endoscopic surgery in Meckel cave. METHODS Meckel cave of 5 adult skulls (10 sides) were fixed with 10% formalin. The anatomical structures of Meckel cave and the related zones adjacent to Meckel cave were observed and measured with endoscopic endonasal app...

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...

Introduction Petrous apex cholesterol granulomas (PACGs) are uncommon lesions. Recurrence following transcranial or endonasal approaches to aerate the cyst occurs in up to 60% of cases. We describe the technical nuances pertinent to the endonasal endoscopic management of a recurrent symptomatic PACG and review the literature. Results A 19-year-old woman presented with a recurrent abducens nerve...

Background: Currently, transsphenoidal surgery is considered the procedure of choice for treating most sellar lesions. There are two different surgical options for performing the transsphenoidal procedure, the transseptal and the endonasal techniques. Objective: the aim of this study is to compare transseptal and endonasal approaches in endoscopic transsphenoidal surgery for pituitary tumors re...
