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...

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...

BACKGROUND The past two decades have been the setting for remarkable advancement in endonasal endoscopic neurosurgery. Refinements in camera definition, surgical instrumentation, navigation, and surgical technique, including the dual surgeon team, have facilitated purely endonasal endoscopic approaches to the majority of the midline skull base that were previously difficult to access through th...

OBJECTIVES Access to the pterygopalatine fossa is very difficult due to its complex anatomy. Therefore, an open approach is traditionally used, but morbidity is unavoidable. To overcome this problem, an endoscopic endonasal approach was developed as a minimally invasive procedure. The surgical aim of the present study was to evaluate the utility of the endoscopic endonasal approach for the mana...

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...

OBJECTIVES/HYPOTHESIS Advances in the field of skull base surgery aim to maximize anatomical exposure while minimizing patient morbidity. The petroclival region of the skull base presents numerous challenges for surgical access due to the complex anatomy. The transcochlear approach to the region provides adequate access; however, the resection involved sacrifices hearing and results in at least...

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 ...

The advent of endoscopic technologies and techniques has expanded the limits of conventional endoscopic sinus surgery. The expanded endonasal approach describes a series of surgical modules in the sagittal and coronal planes that allow surgical access to the entire ventral skull base. The sagittal plane extends from the frontal sinus to the second cervical vertebra. The coronal plane extends fr...

We describe a supra-diaphragmatic ectopic pituitary adenoma that was safely removed using the extended endoscopic endonasal approach, and discuss the value of three-dimensional (3D) endoscopy and intra-operative magnetic resonance imaging (MRI) to this type of procedure. A 61-year-old-man with bitemporal hemianopsia was referred to our hospital, where MRI revealed an enhanced suprasellar tumor ...
