Meningiomas of the sellar region represent approximately 4%–10% of all intracranial meningiomas [3, 7, 9], involving the tuberculum sellae, anterior clinoid processes, diaphragma sellae, and planum sphenoidale. Because of their association with important vascular and functional regions their treatment causes some major problems. Besides endocrinological disturbances, headaches, seizures, and mental disorders, visual loss and bitemporal hemianopsia are common symptoms. Operative mortality and mobidity have been improved by microsurgical methods and progress in neuroanesthesia and intensive care [10]. The postoperative visual outcome is an important problem for the patient and may worsen the prognosis of these tumors. In this study 40 tumors of the sellar region presenting visual symptoms were reviewed to evaluate the postoperative course of visual disturbances and prognostic criteria.

Let me express my sincere appreciation for this honor, whose significance is apparent to me and which moves me deeply. Let me also include in this honor those who have gone with me a part of the way in the realization of our goals as neurosurgeons in Gottingen and in Wurzburg. Two of them, Hans-Jochim Weber and Horst Wenker, team members in the initial phase, are no longer among us.

Between 1980 and 1985, 24 children and adolescents (age range 1.9–18 years) suffering from pharmacoresistant epilepsies, predominantly complex partial seizures, were treated in our institution. Nearly all patients were admitted from epilepsy centers.

Dieses Thema ist in den letzten Monaten, gemessen an dem Umfang und der Haufigkeit der Eingriffe mit dieser neuen Therapie, uberproportional abgehandelt worden, im Hinblick auf den kurzen Zeitraum der Erfahrung fast schon erschopfend. Ich erinnere hier an die Referate und Diskussionen bei der Jahrestagung der Deutschen Gesellschaft fur Neurochirurgie im Juni 1984 und an die Jahrestagung der Deutschen Gesellschaft fur Orthopadie und Traumatologie im September 1984 in Nurnberg, an zahlreiche ortliche und regionale Veranstaltungen der Anwender und Veroffentlichungen im Deutschen Arzteblatt und in anderen medizinischen Zeitschriften.

The problem as to the extent of clearance of the disc affected by degeneration falls within the scope of disc surgery. It is discussed in many publications in relation to recurrence, discitis and aseptic necrosis as well as to the intra- and retroperitonal complications which may be caused by the operation. In 1971, we altered our method of clearing the intravertebral space in lumbar disc operations. In this paper we compare one year’s patients before (1969) with another year’s patients after (1972) alteration of the surgical method by evaluating the clinical record material and discuss the three major points specified above.

In contrast to aneurysms with subarachnoid hemorrhage or intracerebral hematomas, the timing of surgery in cases of large aneurysms is not primarily dependent on the rupture or the danger of recurrent bleeding. Giant aneurysms are defined as aneurysms with a diameter of more than 2.5 cm according to MORLEY (12). Normally these aneurysms do not attract attention because of a rupture but because they lead to signs of a space-occupying lesions and brain compression (9, 18).

In 1974 at the Symposium on Cerebral Angiomas in Giesen (1, 2), we made reference to 20 cases of deep-seated arteriovenous angiomas situated in or near to the midline. We had operated on 17, three of whom subsequently died. In two cases, this was due to the necessity of operating in a state of acute progressive hemorrhage. In the meantime significant progress in both neurosurgery and neuroradiology has expanded therapy of A-V malformations and made it safer.

In an unselected series of cases at the University Neurosurgical Clinic of Gottingen we have seen 56 angioma cases, 20 of which were located in or near the midline of the brain.

Von den peripheren Nerven wird der N. ulnaris auf Grund seiner exponierten Lage am Ellenbogengelenk durch stumpfe Traumen, knocherne Umbauvorgange und starkere Beanspruchungen des Ellenbogengelenks am haufigsten geschadigt. Ein ganz besonderes Interesse wurde von jeher seinen sog. Spatlahmungen zuteil, da nur schwer verstandlich ist, warum noch 30 und mehr Jahre nach einer Ellenbogenverletzung Storungen der Nervenleitung ohne Bruckensymptome auftreten. Es handelt sich dabei um eine chronische Druckschadigung, die zu einer kompletten oder partiellen Axonotmesis fuhrt und nach Beseitigung ihrer Ursache vollstandig ruckbildungsfahig ist. Die Verlagerung des Nerven auf die Beugeseite des Gelenks, subcutan oder unter die Flexorenansatze, ist daher bei Annahme einer Schadigung am Ellenbogen die Therapie der Wahl.
