background: proposing a strategy for sellar reconstruction in endoscopic transsphenoidal transsellar approach for pituitary adenoma. methods: 240 patients with pituitary adenoma underwent pure endoscopic endonasal transsphenoidal surgery. intra-operative csf leaks were classified as grade 0, no observable leak grade 1, csf dripping through an arachnoid membrane defect of less than 1 mm and grad...

BACKGROUND No data on results of repeated transsphenoidal surgery via the endoscopic technique for patients with persistent or recurrent Cushing's disease are available. DESIGN AND PATIENTS We retrospectively evaluated the remission rates and complications of repeated transsphenoidal surgery via the endoscopic technique in 14 patients with persistent (N = 6) or recurrent (N = 8) Cushing's dis...

Title: Effectiveness of endoscopic endonasal transsphenoidal surgery using a neuronavigation: Clinical results of 178 pituitary adenomas Background: The present study assesses endoscopic endonasal transsphenoidal surgery using neuronavigation for pituitary adenoma. Methods and findings: Data were analyzed from 178 consecutive patients with pituitary adenomas who underwent endoscopic endonasal t...

A conchal non-pneumatized sphenoid sinus was previously considered to be a contraindication to the endoscopic transsphenoidal route to the sella due to its small sellar floor and poor anatomical landmarks, such as the optic nerve canal, opticocarotid recess and internal carotid arteries canal. The present study aimed to investigate the methodology and characteristics of the endoscopic transsphe...

Background &Aim: The endoscopic endonasal transsphenoidal approach has been widely employed as a treatment for pituitary adenomas and other parasellar tumors. However, the major concerns related to endoscopic endonasal transsphenoidal surgery include the risks of CSF leak post-operatively leading to morbidity and at times mortality due to severe meningitis. Several studies in the past have foun...

BACKGROUND Endoscopic transsphenoidal surgery has gradually come to be regarded as a preferred option in the treatment of pituitary adenomas because of its advantages of improved visualization and its minimal invasiveness. The aim of this study was to compare and evaluate the outcomes and complications of endoscopic and microscopic transsphenoidal surgery in the treatment of pituitary adenomas....

Endoscopic surgery has been performed in our Department since 1996 as assistance in micro-neurosurgical procedures. In the same way the endoscope was used in transsphenoidal pituitary surgery, but from the beginning of 2004 we started with "pure" endoscopic surgery. We present our experience with the first ninety patients to demonstrate our way of operating. Endoscopic pituitary surgery is perf...

Endoscopic transsphenoidal pituitary surgery has become increasingly more popular for the removal of pituitary adenomas. It is also widely recognised that transsphenoidal microscopic removal of pituitary adenomas is a well-established procedure with good outcomes. Our objective was to meta-analyse the short-term results of endoscopic and microscopic pituitary adenoma surgery. We undertook a sys...

BACKGROUND Binostril endoscopic transsphenoidal approach (BETA) provides sufficient manipulation space and wide endoscopic vision, although it increases the trauma of nose. Mononostril endoscopic transsphenoidal approach (META) has minimal trauma of nose, at the expense of space within the operation. We describe a one-and-a-half nostril endoscopic transsphenoidal approach (OETA) that combines t...

BACKGROUND With continuing advancements in minimally invasive endoscopic nasal and sinus surgical techniques, image-guided endoscopic transsphenoidal approaches to the pituitary gland and anterior skull base have progressively become more popular. METHODS Clinical records were reviewed retrospectively from 2001 to 2006. Twenty-nine consecutive patients with pituitary tumours underwent transna...
