INTRODUCTION • OBJECTIVES • To compare and contrast the three different surgical approaches to the sellar region including the transcranial, transseptal transsphenoidal and the fully endoscopic endonasal approach • To describe the operative technique and our experience with the fully endoscopic endonasal approach • To display the results from our series of 1,000 patients who underwent fully endoscopic pituitary adenoma resections • To compare the outcomes and complication rates of endoscopic vs. microscopic pituitary surgery FULLY ENDOSCOPIC SELLAR AND PARASELLAR SURGERY 002
INTRODUCTION • TUMORS OF THE SELLAR REGION • Pituitary adenomas are the most common sellar tumors • after the age of 30 and they represent 10% of all • intracranial tumors • OTHER TUMORS • May mimic pituitary tumors radiologically and clinically • Craniopharyngiomas • Meningiomas • Rathke's cleft cysts • Epidermoid tumors • Arachnoid cyst • Carotid aneurysms • Others • ANATOMY OF THE SELLAR REGION FULLY ENDOSCOPIC SELLAR AND PARASELLAR SURGERY 004
INTRODUCTION • BRIEF HISTORY • Transcranial, 1889, Victor Horsley • Transseptal Transsphenoidal, 1909, Harvey Cushing (Schloffler, Kanavel, Halstead, Hirsch, and others) • Microsurgical transsphenoidal, 1970s, Jules Hardy • Early trials with the endoscope, 1970’s – 1990’s (Guiot, Apuzzo, others) • MODERN ENDOSCOPIC PITUITARY SURGERY • Early 1990s, Endoscope-Assisted, (Including a series of patients at the SBI demonstrated 33-49% residual tumor only recognized with the endoscope) • Fully Endoscopic • OPEN TRANSCRANIAL FULLY ENDOSCOPIC FULLY ENDOSCOPIC SELLAR AND PARASELLAR SURGERY 006
THE FULLY ENDOSCOPIC ENDONASAL APPROACH • ADVANTAGES • A completely endonasal approach • A targeted approach • A more clear visualization - Contact anatomy • A panoramic view - Angled endoscopes • A more complete operation leading to a lower rate of recurrence • FULLY ENDOSCOPIC ENDONASAL APPROACH FULLY ENDOSCOPIC SELLAR AND PARASELLAR SURGERY 008

SUMMARY AND CONCLUSION • SUMMARY • Endoscopy provides distinct advantages over microscopy • Allows for focus on preserving neurological function and reducing morbidity • Modern pituitary surgery has few complications and requires only a short hospitalization • CONCLUSION • Skull base surgery has benefited significantly from advances in biotechnology • Impact upon the efficacy of tumor resection and subsequent rates of recurrence is significant • New stereoscopic endoscopes FULLY ENDOSCOPIC SELLAR AND PARASELLAR SURGERY 022
