Background and Aim: EETA (Endoscopic Endonasal Transsphenoidal Approach) is a preferred choice for pituitary tumors. offers minimal invasiveness, fewer complications, better outcomes than the sublabial or transseptal microscopic approach. has three approaches: mononostril endoscopic transsphenoidal approach, binostril one half nostril This study aims to compare different EETAs between transcran...

BACKGROUND Numerous technological adjuncts are used during transsphenoidal surgery for nonfunctioning pituitary adenomas (NFPAs), including endoscopy, neuronavigation, intraoperative magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) diversion, and dural closure techniques. OBJECTIVE To generate evidence-based guidelines for the use of NFPA surgical techniques and technologies. MET...

To the Editor: We read with great interest the article by Marić et al (1) on the outcomes of pure endoscopic transsphenoidal surgery (PEETS). Since PEETS is a relatively new surgical technique, data on its effectiveness and safety are very valuable, which makes this article an important contribution to the field. However, we have some concerns about the protocol of the study regarding the bioch...

Microfibrillar collagen hemostat (MCH) is accepted as an effective topical hemostatic agent during endoscopic endonasal transsphenoidal surgery (EETS), particularly to achieve venous hemostasis; however, handling MCH may be troublesome because of its adherence to gloves and instruments. We describe here a method of "injection" of MCH suspension using a syringe applicator. This technique allows ...

BACKGROUND Endoscopic anterior skull-base surgery has been previously suggested to cause a significant deterioration in olfactory function. Given the impact on quality of life, the objective of this study was to determine the effect of a unilateral middle-turbinate-sacrificing approach on olfactory function and sinonasal outcome. METHODS Prospective cohort study comparing olfactory and sinona...

Introduction. Endonasal endoscopic approach has entered recently like a strong option for pituitary tumors treatment. Material and method. A prospective, controlled, randomized and double blind surgical assay was carried out in 41 patients with regional sellar lesions between August 2002 and July 2004. Effectiveness of this method in relation to the microscopic transphenoidal one was evaluated....

 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 ...

INTRODUCTION It is unclear whether the proportions of remission and the recurrence rates differ between endoscopic transsphenoidal surgery (TS) and microscopic TS in Cushing's disease (CD); thus, we conducted a systematic review and meta-analysis to evaluate studies of endoscopic TS and microscopic TS. METHODS We conducted a comprehensive search of PubMed to identify relevant studies. Remissi...

OBJECTIVE Complete sellar floor reconstruction is critical to avoid postoperative cerebrospinal fluid (CSF) leakage during transsphenoidal surgery. Recently, the pedicled nasoseptal flap has undergone many modifications and eventually proved to be valuable and efficient. However, using these nasoseptal flaps in all patients who undergo transsphenoidal surgery, including those who had none or on...
