AIM Postoperative cerebrospinal fluid (CSF) leak following endoscopic endonasal transsphenoidal surgery (EETS) is associated with increased morbidity and mortality. This prospective study is the first evaluation of using autologous fibrin sealant for preventing postoperative CSF leak and related complications. MATERIAL AND METHODS 200 endoscopic endonasal transsphenoidal approaches were inclu...

OBJECTIVE Mucoceles are progressive, slow-growing lesions of the paranasal sinuses that, left untreated, can erode into surrounding structures. Complete obliteration and exenteration of the frontal sinus via a bicoronal skin incision and frontal craniotomy is the standard neurosurgical approach to treat these lesions. TECHNIQUE We describe two patients who underwent a combined supraciliary "k...

The endoscopic endonasal transclival approach has been widely described for its use to resect clivus chordomas, but there have only been isolated reports of its use for petroclival meningiomas. These tumors are most often resected utilizing open transpetrosal approaches, but these operations, difficult even in the hands of dedicated skull base surgeons, are particularly challenging if the menin...

A transcranial approach in combination with a transpetrosal setting has been the mainstream of surgical treatment of cholesterol granulomas in the petrous apex. However, endoscopic endonasal surgery has become a choice of treatment for these lesions with recent advancements in surgical techniques and instruments. We report a successful case of cholesterol granuloma managed with endoscopic endon...

We report herein a case of lower clival chondroid chordoma, focusing on the surgical procedure of endoscopic endonasal surgery. A 36-year-old woman presented with progressive headache, right shoulder pain, and right hypoglossal nerve palsy. Computed tomography (CT) and magnetic resonance (MR) imaging revealed an extradural tumor located in the lower clivus, including the anterior aspect of the ...

The midline skull base is an anatomical area, which extends from the anterior limit of the anterior cranial fossa down to the anterior border of the foramen magnum. For many lesions of this area, a variety of skull base approaches including anterior, antero-lateral, and postero-lateral routes, have been proposed over the last decades, either alone or in combination, often requiring extensive ne...

OBJECTIVE The aim of this study was to describe the use of equine pericardium sheet (Lyomesh (®) ) as dural substitute for sellar reconstruction after endoscopic endonasal transsphenoidal surgery for the removal of pituitary adenomas. METHODS We reviewed data of patients that underwent surgery by means of an endoscopic endonasal transsphenoidal approach for the removal of pituitary adenomas o...

Background: Skull base chordoma is a rare tumor with slow and progressive growth. Significance of this tumor is it’s difficult to access location in skull base. This is the reason for various proposed techniques for resection of the tumor. Endoscopic endonasal technique is a minimally invasive approach that gives surgeons opportunity of total resection of tumor and low morbidity. Total resectio...

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...

This study aims to evaluate indications, complications and surgical technique in the endonasal endoscopic approach to orbital tumor resection. In this retrospective review, 11 patients who admitted and underwent endoscopic orbital surgery were reviewed. Demographics, preoperative and postoperative eye examination, and size and imaging characteristics of the tumours were tabulated. The endonasal...
