A new technique of endoscopic decompression of suprasellar craniopharyngioma cyst

Introduction Craniopharyngiomas represent a unique management challenge. Aggressive surgical management has traditionally been associated with high rates of morbidity. Modern surgical techniques, and increasing practice of subtotal resection followed by radiosurgery, have reduced morbidity and mortality rates. One cause of postoperative morbidity, and indeed mortality, is aseptic meningitis from spill-out of craniopharyngioma cyst contents. We have developed a surgical technique for the management of large craniopharygngioma cysts extending into the third ventricle, to reduce this risk.
