    Notes: Summary In 56 neurosurgical patients 70 percutaneous needle trephinations were performed. This method was mostly used in patients with acute increase of ICP due to occlusive hydrocephalus of various aetiologies. Thanks to the accuracy and exhaustiveness of CT information, and thanks to the simplicity and safety of percutaneous needle trephination, this latter could be more and more used in daily clinical practice as a diagnostic and therapeutic procedure, for example for the study of adult hydrocephalus, for provisional external ventricular drainage, for treatment of CSF infections, and for ventricular bleedings (also in newborns and premature infants). No serious complication was seen even after prolonged CSF drainage over a period of 41 days. The method of PNT, as described in detail, can be used under sterile conditions at the bedside, on the stretcher in the emergency room, or in the CT or X-ray laboratory. It fulfils the criteria for clinical acceptance: simplicity, low risk, reliability, exactness, and effectiveness.

    Description / Table of Contents: Zusammenfassung Nach Darstellung der topographischen Anatomie werden die verschiedenen operativen Zugangswege zum Tentoriumschlitz und ihre technische Ausführung anhand einiger Beispiele erläutert. Durch den pterionalen Zugang können Prozesse im supratentoriellen Bereich des vorderen und mittleren Drittels der Inzisura tentorii angegangen werden. Hierbei kann der Zugang zum infratentoriellen Raum durch Einschneiden und Hochnähen des Tentoriumrandes erweitert werden. Der mediale occipitale Zugang ist geeignet für die medial gelegenen raumfordernden Prozesse im aufsteigenden Abschnitt, d.h. im hinteren Drittel des Tentoriumrandes. Die infratentoriellen Geschwülste des Kleinhirnbrückenwinkels und des präpontinen Raumes mit Ausdehnung in den Tentoriumschlitz werden von lateral suboccipital angegangen. Ein subfrontales infrachiasmatisches Vorgehen kann bei suprasellären Prozessen mit parasellärer Ausdehnung in den Tentoriumschlitz angezeigt erscheinen, wenn es die Lage des Chiasma opticum erlaubt. Darüber hinaus kann die Lokalisation des Prozesses eine Kombination einzelner Zugänge erfordern.
    Notes: Summary After a description of the topographic anatomy, the different approaches to the tentorial notch and the details of technique are illustrated by a few examples. The pterional approach permits surgical treatment of lesions in the supratentorial region of the anterior and middle third of the tentorial opening. Any approach to the infratentorial region can be enlarged and improved by incising and stitching back the free margin of the tentorium. The medial occipital approach is appropriate for space-occupying lesions situated medially in the ascending portion, that is in the posterior third of the free margin of the tentorium. Infratentorial tumours in the cerebello-pontine angle and in the prepontine region, with extension into the tentorial notch, are best treated through the lateral suboccipital approach. A subfrontal infrachiasmatic procedure is indicated in the case of suprasellar lesions with parasellar extension into the tentorial notch, if the anatomy of the optic chiasm allows it. The location of any particular lesion may call for a combination of different approaches.

    Notes: Abstract In 11 cases of intracranial, temporal arachnoid cysts the etiology, clinical and radiographic findings, surgical treatment, and outcome are reviewed in respect of post-traumatic subdural hematoma. Cysts of the middle cranial fossa are susceptible to trauma, which may cause bleeding either into the cyst or into the subdural space. Signs and symptoms of increasing intracranial pressure (ICP), local neurological deficits, and sometimes epileptic seizures may lead to hospitalization. CT or MRI scans are diagnostic in these cases. In cases of intracranial mass lesion with displacement of the midline structures and increasing ICP, osteoplastic craniotomy is performed and the lateral wall of the cyst is resected down to the tentorial notch by a microsurgical procedure, with opening into the basal cisterns. There were no operative or postoperative complications in 11 consecutive cases. However, one boy required a cystoperitoneal shunt 3 months later as a result of hydrocephalus following subdural hematoma. Asymptomatic arachnoid cysts are discussed with respect to brain function and social behavior.
