BACKGROUND The purpose of this prospective, observational study was to evaluate the management of skull base chordomas surgically resected via a 3D-endoscopic transnasal approach. METHODS Thirteen consecutive patients were observed and only 9 were surgically treated using a 3D-endoscopic transnasal approach assisted by a novel 3D visualization system. RESULTS Nine consecutive male patients ...

The surgical results of 18 cases of clival/upper cervical chordoma treated in the last decade via the endoscopic endonasal approach (EEA, 9 cases) and the transoral-transpalatal approach (TO-TPA, 9 cases) were compared. Each group showed the same incidence of subdural invasion, with 5 cases each. The superior (frontal base) and lateral surgical fields were wider by EEA, but the inferior view lo...

Background: Salivary gland tumours are relatively uncommon and constitute 3% to 10% of all head & neck neoplasms. The majority salivary arise in the parotid gland.
 Objectives: To search clinicopathological presentation tumours.
 Methods: This was a cross sectional study.
 Results: highest incidence benign tumors 3rd 4th decade, whereas for malignant tumor it 5thdecade life. ...

AIM To study and summarize our experience with the subtemporal transtentorial approach for resection of petroclival tumors. MATERIAL AND METHODS Twenty-eight patients who suffered from petroclival tumors and underwent tumor resection via a subtemporal transtentorial approach between October 2010 and July 2013 were retrospectively reviewed. RESULTS Total resection was performed in 22 cases, ...

Chordoma is a primary sacral neoplasm of ectodermal origin and makes up %1- 4 of all primary bone tumors. It is usually present on the midline cerebrospinal axis and the most common locations are the spheno-clival region and the sacrum. The treatment of primary sacral tumors represents a challenge because of a large tumor mass at presentation and a hemorrhage risk in surgery. Sacral tumors may ...

Introduction Giant cell-rich osteosarcoma (GCRO) is a rare pathologic diagnosis, and most cases have involved the appendicular skeleton. We present a challenging diagnosis of GCRO of the skull base treated with an endoscopic endonasal approach. Case Presentation An 18-year-old female patient presented with acute monocular visual loss. Imaging revealed a large clival mass encasing the internal c...

Endoscopic endonasal skull base surgery (EESBS) is undergoing a remarkable evolution as in the last two decades it shifted from pituitary surgery to a myriad of approaches extending from the cribriform plate to C2 and laterally to the petrous apex and to the infratemporal fossa. The collaboration with ENT surgeons, technological advances in the field of instrumentation and endoscopic systems, a...
