Ricardo Mingarini Terra, Juliano Ribeiro Andrade, Alessandro Wasum Mariani, Rodrigo Gobbo Garcia, Jose Ernesto Succi, Andrey Soares, Paulo Marcelo Zimmer
The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as neurosurgery and cardiovascular surgery, it has rarely been explored in thoracic surgery. Our objective was to discuss the possible applications of this technology in thoracic surgery, through the reporting of three cases...

BACKGROUND: Pediatric low-grade gliomas (LGGs) account for approximately half of all pediatric central nervous system tumors. The low-grade gliomas' first line of treatment is gross total resection. However, when gross total resection is not possible, options for adjuvant therapy are limited. MRI-guided laser ablation (magnetic resonance-guided laser interstitial thermal therapy (MRgLITT)) offers a new option for treatment in selected cases. We present a description of the current MRgLITT technology and an exemplary case-series review of our experience in its use in LGGs...

The technological advancement of optical approaches, and the growth of their applications in neuroscience, has allowed investigations of the physio-pathology of neural networks at a single cell level. Therefore, better understanding the role of single neurons in the onset and progression of neurodegenerative conditions has resulted in a strong demand for surgical tools operating with single cell resolution. Optical systems already provide subcellular resolution to monitor and manipulate living tissues, and thus allow understanding the potentiality of surgery actuated at single cell level...

TOPICALITY: The fast track technology means a complex of targeted measures involving rational preoperative preparation, minimally invasive surgery, regional anesthesia and short-acting anesthetics, and early postoperative rehabilitation. Elucidating the possibility of applying the fast track technology in neurosurgery, in particular in spinal surgery, is extremely topical. This is associated with the epidemiological data and the fact that minimally invasive techniques used in neurosurgery are highly expensive...

Neuronavigation, a ubiquitous tool used in neurosurgery, is rarely used in maxillofacial reconstructive surgery despite it offering many advantages without any disadvantage to the patient. The present report describes one patient with complex gun-shot wound facial injury and one patient with a rare malignant peripheral nerve sheath tumor involving the skull base, in which neuronavigation was used to improve the accuracy of bony reduction and minimize surgical invasiveness. Although neuronavigation is not necessary for all maxillofacial surgery, it can be a useful adjunct in complex maxillofacial reconstruction and maxillofacial tumor resection...

The subspecialty of craniofacial surgery emphasizes skeletal exposure, preservation of critical structures, and provision of a superior cosmetic result. In recent decades, an emphasis on minimally invasive neurosurgical exposure has paved the way for increased collaboration between neurosurgeons and craniofacial surgeons.The 1990s saw the growing popularity of an eyebrow incision for orbital roof craniotomies in neurosurgery to address lesions in the anterior skull base. Disadvantages of this approach included conspicuous scarring above the brow skin, risk of injury to the frontal branch of the facial nerve, and numbness from supraorbital or supratrochlear nerve transection...

We retrospectively studied the anamnesis, in particular the etiology, the clinical picture, and computed tomography/magnetic resonance imaging/ultrasound data, in the dynamics of a heterogeneous group of 127 patients with neurological and psychiatric pathological conditions. We were interested in the reasons for the occurrence, the clinical value of various neuroimaging abnormalities in the white matter of the brain, including the periventricular zone, the communication of their occurrence with the possible exit of CSF outside of the limits of the ventricular system...

Neuronavigation has become an essential neurosurgical tool in pursuing minimal invasiveness and maximal safety, even though it has several technical limitations. Augmented reality (AR) neuronavigation is a significant advance, providing a real-time updated 3D virtual model of anatomical details, overlaid on the real surgical field. Currently, only a few AR systems have been tested in a clinical setting. The aim is to review such devices. We performed a PubMed search of reports restricted to human studies of in vivo applications of AR in any neurosurgical procedure using the search terms "Augmented reality" and "Neurosurgery...

OBJECTIVE: The management of pineal region tumors depends on the histologic subtypes. Two minimally invasive techniques are available: endoscopic intraventricular biopsies and stereotactic biopsies. The recent Southampton and Lille series are the largest endoscopic and stereotactic series of pineal region tumors reporting both diagnosis rate and accuracy rate, respectively; we elaborated on these results in the light of other recent studies. METHODS: We compared the Southampton endoscopic series with the Lille series, reflecting our 25-year experience of stereotactic biopsies, and the metadata of the literature for both approaches, as reported in the 2013 Report of the French-Speaking Society of Neurosurgery on tumors of the pineal region...

Spinal surgery under Eastern-African circumstances is technically demanding and associated with significant complications, such as blood loss, infection, and wound breakdown. We report a spinal trauma case that was performed using minimally invasive surgery (MIS) and navigation, and hypothesize that these newer techniques may enable surgeons to perform effective spinal surgery with minimal complications and good outcomes.  During the 2014 First Hands-on Neurotrauma Course held in Dar es Salaam, Tanzania, we successfully performed three minimally invasive and two-dimensional (2D) navigated spinal surgeries to decompress and stabilize patients with complete and incomplete spinal injuries...

Current optical approaches are progressing far beyond the scope of monitoring the structure and function of living matter, and they are becoming widely recognized as extremely precise, minimally-invasive, contact-free handling tools. Laser manipulation of living tissues, single cells, or even single-molecules is becoming a well-established methodology, thus founding the onset of new experimental paradigms and research fields. Indeed, a tightly focused pulsed laser source permits complex tasks such as developing engineered bioscaffolds, applying calibrated forces, transfecting, stimulating, or even ablating single cells with subcellular precision, and operating intracellular surgical protocols at the level of single organelles...

Symptomatic intracranial arachnoid cysts are commonly treated using neuroendoscopy. Cysts located within the posterior fossa may present a greater surgical challenge to the neurosurgeon due to the numerous vital neurovascular structures located within this confined space. Adding neuronavigation during endoscopy helps a neurosurgeon to visualize and utilize both anterior and posterior corridors safely to access and manage these lesions. We present three symptomatic posterior fossa arachnoid cysts that were treated successfully using minimally invasive neuronavigation-guided endoscopic neurosurgery utilizing the anterior transfrontal transaqueductal, anterior transfrontal transtrigonal, and posterior suboccipital infratentorial supracerebellar approaches...

Percutaneous endoscopic lumbar discectomy(PELD)has been used as a standard surgical technique for lumbar disc herniation at the Southern TOHOKU Healthcare Group since its introduction in 2009. We present our clinical experiences with PELD for 6 years and discuss the decision-making process for its surgical indication with a review of the pertinent literature. PELD can be performed under both local anesthesia and general anesthesia, and requires only a stab wound for surgery and 3 days of hospitalization. Our surgical results showed generally satisfactory outcomes; however, a salvage surgery was required for 10 of the 96 patients(10...

OBJECTIVE In appropriate candidates, the treatment of medication-refractory mesial temporal lobe epilepsy (MTLE) is primarily surgical. Traditional anterior temporal lobectomy yields seizure-free rates of 60%-70% and possibly higher. The field of magnetic resonance-guided focused ultrasound (MRgFUS) is an evolving field in neurosurgery. There is potential to treat MTLE with MRgFUS; however, it has appeared that the temporal lobe structures were beyond the existing treatment envelope of currently available clinical systems...
