title: [Transsphenoidal surgery of intrasellar and perichiasmatic tumors--personal experience].
abstract: Microsurgical transsphenoidal approach has been for decades an established standard surgical treatment of pituitary adenomas. Actually it offers a safe and rapid midline access to the sellar region with a minimal risk of injury to vascular vessels, the optic chiasm or nerves and the brain. Major limitations of this approach are due to the narrow and deep operating field, with the related possible complications of the pituitary insufficiency and the cerebrospinal fluid rhinorrhea. In this paper the authors present their own experience with transsphenoidal surgery they performed in over 1500 cases during the past 28 years. The history and evolution of the microsurgery are described, including the operative technique, indications and counter-indications, as well as relative advantages and disadvantages of the transsphenoidal approach. Moreover, current modifications of the neurosurgical technique (extended transsphenoidal approaches) and their application in the treatment of non-glandular perichiasmatic tumors are outlined and discussed.
