INTRODUCTION The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium. OBJECTIVE To report one case of sphenoid sinus mucocele that occurred with headache and was submitted to surgical treatment through endonasal endoscopy approach. CASE REPORT 59-year-old male ...

INTRODUCTION Optic nerve compression is an uncommon disorder leading to deterioration or complete loss of vision. CASE PRESENTATION We describe the case of a 14-year-old Caucasian girl with a gradual deterioration of vision in her right eye. Using modern imaging techniques and endonasal endoscopic surgery, we identified the cause and removed the pathology. CONCLUSIONS The cause of optic ner...

Objective In this study, we investigate our institutional experience of patients who underwent endoscopic endonasal transsphenoidal approach for treatment of large and giant pituitary adenomas emphasizing the surgical results and approach-related complications. Method The authors reviewed 28 consecutive patients who underwent surgery between March, 2010 and March, 2014. Results The mean preoper...

BACKGROUND The purpose of this study was to report our experience with the endoscopic management of sinonasal schwannomas, analyzing the advantages, limitations, and outcomes of the technique. METHODS A retrospective analysis was carried out on 11 patients treated endoscopically between 2000 and 2014 at a single institution. RESULTS Eight patients underwent an exclusive endoscopic endonasal...

The indications for endonasal endoscopic approaches to diseases of the skull base and its adjacent structures have expanded considerably during the last decades. This is not only due to improved technical possibilities such as intraoperative navigation, the development of specialized instruments, and the compilation of anatomical studies from the endoscopic perspective but also related to the a...

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 analyze possible etiological factors of spontaneous cerebrospinal fluid (CSF) rhinorrhea and to assess the outcomes of endonasal endoscopic repair. DESIGN Retrospective study. SETTING Academic neurosurgical hospital. Patients Twenty-one consecutive patients who presented with spontaneous CSF leak and underwent endonasal endoscopic surgery from January 1999 through December 2001...

Meningoencephalocele is a rare condition that usually occurs in children and is treated by neurosurgeons with occasional help from ENT doctors. The symptoms of meningoencephalocele might not develop until adulthood, but usually they are apparent immediately after birth. The case of small anterior basal transethmoidal meningoencephalocele in a 24-year-old patient who had headaches and runny nose...

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...

BACKGROUND Sphenoorbital meningiomas are surgically challenging because of their nature to extend to adjacent structures. Here, we describe a case of recurrent sphenoorbital meningioma extending into the sphenoid sinus, pterygopalatine fossa, and infratemporal fossa, which was resected using combined simultaneous transcranial and endoscopic endonasal approaches. CASE DESCRIPTION A 62-year-old...
