V arious procedures both physical and surgical have been used in the treatment of acromegaly, and results are mixed. 1–3, 10, 14, 20, 21, 23, 25–28, 31, 37, 39, 43, 44, 47 The goal of the treatment is to lower plasma growth hormone to normal levels without affecting normal pituitary function, and for this transsphenoidalmicrosurgeryrepresents a promising approach. 16, 18, 19 We are reporting our results in a series of 29 consecutive acromegalic patients operated on with this technique. Materials and Methods Clinical Material Twenty-nine patients

the neck but not the fundus filled. Drake and Allcock, 4 reviewing their results in 340 postoperative angiograms, reported a 14% incidence of inadequate obliteration of the aneurysm following clip or ligature. Sato and Suzuki 12 reported that only 4% of a series of 262 aneurysms were incompletely occluded. Recently, there has been a significant increase in the use ofmicrosurgeryfor intracranial aneurysms. Reports confirm that the high degree of illumination and magnification obtained by the surgical microscope has improved the postoperative mortality and

accelerators, 10 charged-particle irradiation, 2,5,6,29,34,35 or GKS 18,22,26,28 has been used as a complement to resection. Good results have been reported for all of these treatments, but the long-term follow-up studies that are required for these slow-growing tumors have been scarce. In this article we report our 20-year experience with combinedmicrosurgeryand GKS for the treatment of intracranial chondrosarcomas. Clinical Material and Methods Patient Population Between 1987 and 2004 nine patients, four women and five men, with intracranial chondrosarcomas were

The current size of neuroArm allows for only one manipulator to be inserted into the magnet. While surgery is possible with only one manipulator, performance is improved with two. The next generation of neuroArm, neuroArm II, is already in development. The manipulators will be 25% smaller than neuroArm I, which will allow both manipulators to fit into the magnet aperture. The smaller manipulators will also be

D espite great advances inmicrosurgery, morbidity remains an issue after resection for VS. The tumors are now detected much earlier; frequently, patients with newly diagnosed unilateral VS have minimal symptoms, and they often have normal hearing. For these patients, selection of the best management option often presents a therapeutic dilemma. Gamma knife surgery may be an appealing alternative in terms of reduced morbidity. To determine if this was true, we first evaluated functional outcomes in our patients with VS in whom the microsurgical approach was

During the past 12 years (June, 1970, through September, 1982), I have removed 1000 pituitary adenomas using the transsphenoidal technique described by Hardy. 37 More than 75% of these tumors were endocrine-active, and of these, prolactin (PRL)-secreting adenomas were the most frequent; endocrine-inactive tumors accounted

A retrospective analysis was made of prospectively acquired data in a treatment database that included a consecutive series of patients with meningioma treated by a single surgeon over a 4-year period by using bothmicrosurgeryand GKS as part of a consistently applied comprehensive multimodality approach. While the two modalities have been studied head-to-head to
