Accessing intradural lesions via an extended endoscopic endonasal approach requires a relatively large bony removal over the skull base. ⋯ The Sonopet ultrasonic bone curette is a useful tool during endoscopic endonasal skull base surgery.

Since the pioneering studies of human thalamic anatomy based on histology and binding techniques, little new work has been done to bring this knowledge into clinical practice. ⋯ It seems possible to identify the subcompartments of the thalamus by spontaneous MRI contrast, allowing a tissue architectural approach. In addition, the MRI tissue architecture matches the earlier subcompartmentalization based on cyto- and chemoarchitecture. This true 3D anatomic study of the thalamus may be useful in clinical neuroscience and neurosurgical applications.

We compared the origin and quality of regenerating myelinated axons after end-to-side neurorrhaphy or end-to-end neurorrhaphy. ⋯ The current study supports the hypothesis that end-to-side neurorrhaphy represents an opportunity for peripheral nerve repair when a proximal nerve stump is not available.

We report our experience with anterior interhemispheric approach for tumors in and around the anterior third ventricle, including surgical technique, instrumentation, pre- and postoperative hormonal disturbances, and resection rate. ⋯ The minimally invasive anterior interhemispheric approach, with or without opening of the lamina terminalis, is useful for removal of tumors in and around the anterior third ventricle, such as craniopharyngiomas and hypothalamic gliomas.

Recurrences after complete surgical clipping of an aneurysm base are rare. We describe a potential reason for such recurrences: the inappropriate application of a popular aneurysm clip. ⋯ We present here, for the first time, evidence that the small orifice located at the junction of the blade and spring portions of Yaşargil aneurysm clips can lead to failure of initial surgery and/or recurrence. This can be avoided by using clips with slightly longer blades to keep the orifice away from the aneurysm or by applying a second clip to occlude the untreated part.
