The recent introduction of the 3D endoscope for endonasal surgery has been welcomed because of its promise to overcome the main limitation of endoscopy, namely the lack of stereoscopic vision. This innovation particularly regarded the most complex transnasal surgery of the skull base. We therefore discuss our early experience as ENT surgeons with the use of a purely 3D endoscopic expanded 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 To evaluate the usefulness of septal batten grafts to correct cartilaginous septal deformities in endonasal septoplasty. DESIGN Retrospective study. SETTING University medical center. PATIENTS Of 430 patients who underwent endonasal septoplasties from January 2006 to January 2011, 30 received septal batten grafts and were enrolled in the study. Twenty-eight patients were male an...

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: The endonasal endoscopic surgery has stood the test of time in managing inflammatory as well as other diseases affecting nose and paranasal sinuses. Objective: To report our experience with endonasal endoscopic surgery of benign tumors and tumor-like conditions of the nose and paranasal sinuses. Methods: The medical records of 92 patients with tumors and tumor-like conditions, who h...

The objective of present study was to compare the results of endonasal endoscopic dacryocystorhinostomy and external dacryocystorhinostomy. It was a prospective non-randomized study. Forty consecutive patients having complaints of watering with complete naso lacrimal duct obstruction were selected for the study. Dacryocystography was done in all the cases. Selection of type of operation was lef...

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...

Reported cases of acquired posterior choanal atresia are very few in the English literature. A case of acquired posterior choanal atresia post radiotherapy is reported which was treated by endonasal endoscopic repair using microdebrider with untoward effect.
