OBJECTIVES/HYPOTHESIS While there are many benefits to the endoscopic endonasal approach to the infratemporal fossa, involvement of the petrous portion of the internal carotid artery (ICA) poses a unique challenge. The endoscopic endonasal approach requires establishing the relationship of the petrous ICA to anatomical landmarks to guide the surgeon. This study evaluates the relationship of pet...

BACKGROUND The use of interdomal sutures for tip refinement is common in open rhinoplasty and in endonasal rhinoplasty using a delivery technique, but there is paucity of reports in the literature regarding the use of interdomal suturing techniques when the nondelivery endonasal approach is chosen. OBJECTIVE The authors describe a technique designed to refine the nasal tip with an interdomal ...

BACKGROUND The purpose of this study was to present a monocentric retrospective study designed to compare oncologic results and morbidity between transfacial surgery and endoscopic endonasal surgery for nasal adenocarcinomas. METHODS Between 1998 and 2003, 31 patients were operated on via transfacial surgery, and between 2004 and 2009, 43 patients were operated on via endoscopic endonasal sur...

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...

Introducción y objetivo: La patología crónica de la vía lagrimal es frecuente en nuestros días, su tratamiento quirúrgico se realiza mediante técnicas dacriocistorrinostomia (DCR), pudiendo ser por abordaje externo o endonasal. 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...

We report a case of naso-cutaneous fistula due to thermal injury during transcanalicular laser dacryocystorhinostomy followed by superadded infection with coagulase negative staphylococcus in a diabetic patient. The case highlights the importance of meticulous wound care in the management and possibility of its occurrence even with minor thermal injury in immunocompromised patients.

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...
