The technique of transcranial focused ultrasound has emerged as a potentially revolutionary tool in functional neurosurgery. This platform provides a method of ablating specific voxels of brain tissue without surgery. Ablative techniques suffer the disadvantage when compared to neuromodulatory interventions of being largely irreversible. However, as both our understanding of neurology and the technology we have access to improves, minimally invasive techniques such as focused ultrasound will undoubtedly become safer and evolve to play a significant role in the future of functional neurosurgery. In this review, the authors summarise the application of the technique to various common movement disorders.

Chordoma Foundation

Written by

The Chordoma Foundation is a nonprofit organization that aim to improve the lives of chordoma patients through the cooperation of researchers and clinicians. The website presents three different sections: one for patients and the other two for researchers and healthcare professionals. The aim of these latter sections is to help clinicians most effectively treat chordoma and contribute to advance chordoma research. In fact, there are multiple sections about, for example, responses to systemic treatments, clinical trials and the chordoma genome project.

A monthly newsletter with the latest news about treatments and clinical trials is available.

Choosing the Target for Parkinson's Disease

Written by

Deep brain stimulation (DBS) is a surgical procedure used to treat several disabling neurological symptoms - most commonly the debilitating motor symptoms of Parkinson’s disease (e.g. tremor, rigidity, stiffness, slowed movement, and walking problems). The procedure is also used to treat essential tremor and dystonia among other pathologies.

Choosing the best anatomical target for the electrodes is of as much importance as selecting the right patients for the procedure. Dr. Peter Nora shares his experience in the field, and gives advice for successful results. 


Dejerine-Roussy syndrome (or thalamic pain syndrome) is a phenomenon experienced by some patients following thalamic stroke. Such lesions initially may cause hemibody numbness and/or paraesthesia contralateral to the affected hemisphere. This can progress into dysaesthesia and pain in the same distribution over the course of weeks or months. This pain is often refractory to standard treatments with analgesia such as opioids. This paper is a review of the application of DBS in patients with Dejerine-Roussy syndrome. The authors conclude that neuromodulation is a potentially viable management option in these patients when their pain is found to be refractory to other treatments. However, in order to achieve this, more research is required to elucidate potential anatomical targets, and a greater degree of homogeneity is required in the studied patient populations.

Skull Base Cancer Imaging

Written by



Eugene Yu and Reza Forghani





Publication date:

December 2017



Considering the anatomical complexity of bone, vascular and nervous structures of the skull base, medical imaging is essential for identifying neoplastic lesions and planning their treatment.

Thanks to the contribution of experienced radiologists, head and neck surgeons, neurosurgeons and oncologists, this book is presented as an imaging-focused guide on various neoplastic diseases affecting the skull base, with a detailed analysis for each anatomical region. Chapters are divided based on anatomical location, including cranial fossae, nasal cavity, paranasal sinuses, and petroclival and lateral skull base.

This book covers fundamental principles relevant to radiology, neurosurgery, and otolaryngology residents and clinicians who care for patients with head and neck neoplasms.

Dates: January 17 – 19, 2018
Location: Strasbourg, France

This workshop is intended for neurosurgeons from the world over, to learn and practice the technical skills required for skull base surgery. It has been structured to provide both didactic lectures and intensive hands-on cadaver dissection sessions, covering a broad spectrum of transcranial and endoscopic approaches. A panel of distinguished leaders in these fields will deliver lectures focusing on skull base anatomy, surgical approaches and therapeutic strategies for skull base lesions. The scientific program will include a guest speaker session on a topic related to skull base neurosurgery, with lectures given by world-renowned experts. Attendees will benefit from the outstanding surgical lab environment of the IRCAD with state-of-the-art equipment provided by sponsors. For hands-on sessions, a demonstration will be performed at the master station, transmitted onto a screen at each workstation. In the meantime, participants will work as a team of two on prepared injected fixed specimens under the guidance of a distinguished expert faculty.

Without sufficient cytoreduction, petroclival meningiomas often recur, whilst cases in which total resection has been achieved are frequently associated with significant morbidity. In this study, the authors investigated the long-term effects of gamma knife radiosurgery in controlling these tumours. The sample consisted of 89 patients, 58 of whom underwent gamma knife radiosurgery as a primary treatment, whilst the remaining 31 underwent irradiation as an adjuvant therapy to surgery. The authors found that gamma knife was associated with significant disease suppression and control of tumour volume in the majority of the sample, concluding that this platform is a valuable adjunct to the management of petroclival meningiomas. However, large-scale prospective studies are required to confirm these findings and motivate real change in practice.

Skull base surgery of the Orbit and Cavernous Sinus

Written by

A key consideration to successful complex skull base surgery is the anatomy. Tailoring the approach towards every single lesion defines the flow of the surgery. The ability to operate successfully within cavernous sinus and around the orbit largely depends on an improved understanding of the anatomy and pathology in the parasellar region. Dr. Johnny Delashaw explains in detail every single structure on the way to the lesion and how to deal with it without harming nearby vessels and nerves.

Skull Base Congress Website

Written by

Skull Base Congress is a global community of skull base surgeons with a principal objective to facilitate the exchange of educational resources about skull base surgery. After the website registration (basic profile available for free or premium) the user can interact with all the members and have access to different types of materials related to a single clinical case: anatomy spotlight, surgical theatre, quiz and journal club. The aim of Skull Base Congress is to make the learning process fun and effective.


Arachnoid cysts are typically asymptomatic incidental findings, with an estimated prevalence of 2.3%. They are thought to arise from a congenital splitting of the arachnoid mater with CSF subsequently filling this space. Arachnoid cysts are most frequently found in the middle fossa, and may be stratified according to the Galassi classification. In this article, the authors present two cases of women presenting with dysphagia, dysarthria, and tongue weakness and atrophy. MRI confirmed the diagnosis of arachnoid cyst of the hypoglossal canal, and both patients underwent surgical resection. The lesion was approached via the ipsilateral occipital condyle - this is the first report of such an approach being used to access arachnoid cysts of the occipital condyle.
