The extradural minipterional pretemporal approach for the treatment of spheno-petro-clival meningiomas Abstract Background Cavernous sinus and petroclival region is an anatomically complex region in close relationship with important neurovascular structures. As such, the surgical treatment of spheno-petro-clival (SPC) meningiomas represents an operative challenge, in which several routes and its combinations might be used. Methods We describe in detail the surgical technique of the extradural minipterional pretemporal approach (eMPT-P) to the SPC region and highlight the main anatomical key elements involved in this approach as well as the technical aspects for avoiding surgical complications. Conclusion The eMPT-P is a versatile approach that uses the extradural route, and thereby reduces brain retraction, while provides a good angle of exposure of the SPC region.

How I do it? Lumbar cortical bone trajectory fixation with image-guided neuronavigation Abstract Background Cortical bone trajectory was described in 2009 to reduce screw loosening in osteoporotic patients. Since then, it has demonstrated improvements in biomechanical and perioperative results compared to pedicle screws, and it have been described as a minimally invasive technique. Method We describe our experience with the technique assisted by 3D neuronavigation and review some of the complications and tools to avoid them together with limitations and pitfalls. Conclusion Cortical bone trajectory guided by 3D neuronavigation helps to reduce the need for radiation and incidence of complications.

How I do it: tapered rod placement across the cervicothoracic junction for augmented posterior constructs Abstract Background Posterior instrumentation techniques are commonly employed for cervicothoracic fixation. The pedicles of the upper thoracic vertebrae can typically accommodate larger diameter screws than the subaxial cervical vertebrae. In many construct systems, this requires the use of a tapered rod, which can be technically challenging to place. Method Using a three-dimensionally printed biomimetic spine simulator, we illustrate the stepwise process of instrumentation and tapered rod placement across the cervicothoracic junction (CTJ). Conclusion Tapered rod systems can augment the biomechanical stability of cervicothoracic constructs. Ease of rod placement across the CTJ hinges upon a systematic method of instrumentation.

Ictal swearing network confirmed by stereoencephalography: a case report Abstract Ictal swearing, characterized by episodic utterance of deistic, visceral and other taboo words and phrases, is a rare manifestation of epilepsy. Limited manifestation of that elucidate neural network about manifestation of. Here we report a 43-year-old right-handed man who has suffered from refractory epilepsy manifestation of ictal swearing. The stereoencephalography(SEEG) investigation located the seizure onset zone in left orbito-frontal cortex and the involvement of left orbito-frontal and right hippocampus in the propagation of epileptic activities. Surgical resection has made the patient seizure-free. The present case gives us better understanding of these ictal phenomena and helps to optimize the placement of SEEG electrodes in refractory epilepsy patient with ictal swearing.
