Paraclinoidal aneurysms, especially superior hypophyseal artery (SHA) aneurysms (with medial projection), can be challenging to access via a pterional craniotomy and damage to the optic nerve can occur during surgery. The authors have previously reported on endonasal clipping and aneurysmorrhaphy of a vertebral artery aneurysm following proximal and distal protection of the aneurysm using parti...

El objetivo dicho artículo, realización una revisión DCR endoscópica, sus indicaciones, técnica quirúrgica las posibles complicaciones: Método: Revisión narrativa. Resul...

Introduction: Dacryocystitis is a very common pathology and affects significant part of the population. Stenosis nasolacrimal ducts most frequent cause development dacryocystitis, main method treatment dacryocystorhinostomy. Material methods: to study stages dacryocystorhinostomy (DCR), various scientific journals (scientific from which we get information) were used. One first methods surgical ...

OBJECTIVES/HYPOTHESIS In an effort to decrease morbidity, skull base surgeons have explored less invasive approaches to the infratemporal fossa, including endonasal-endoscopy, minicraniotomies, and transantral endoscopic and microscopic corridors. This project presents quantitative data that assesses the practicality, and volumetric exposure afforded by endonasal and open approaches to the infr...

OBJECTIVE In recent years, endoscope started to be used for the excision of the brainstem lesions or those localized in the anterior part of the brainstem. In this paper a case of clival meningioma resected through endoscopic endonasal transclival route has been presented with illustrations, live surgery videos demonstrating the surgery step by step. CASE REPORT A 35-year-old male patient con...

Malignant peripheral nerve sheath tumors (MPNST) are rarely encountered in the paranasal sinuses and frontal skull base. We present histopathological findings, cytometric DNA measurements, and the preliminary results of comparative genomic hybridization analysis of a 46-year-old male patient with a frontobasal MPNST. The tumor was resected via the endonasal approach. No tumor recurrence was det...

Since the introduction of endonasal endoscopic skull base surgery the exclusive purpose in the management of skull base neoplasms has been to increase survival rates. Recently, given the improved prognosis achieved, more attention has been focused on the functional outcomes such as nasal symptoms and quality of life (QOL). The purpose of this review is to assess the functional outcomes after en...

OBJECTIVE Analyse technical aspects, effectiveness and morbidity of the endoscopic endonasal transphenoidal approach for pituitary adenomas. METHOD From January 2005 to September 2008, 30 consecutive patients underwent endoscopic endonasal resection of pituitary adenomas with a follow up from 3 to 36 months. Their medical charts were retrospectively analysed. RESULTS There were 18 women and...

A 41-year-old female patient was admitted with streptococcal meningitis on a background of 5-month history of CSF rhinorrhoea. Imaging revealed an extensive skull base lesion involving the sphenoid and ethmoid sinuses, the pituitary fossa with suprasellar extension and bony destruction. Histological examination of an endonasal transethmoidal biopsy suggested a diagnosis of olfactory neuroblasto...

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 ...
