RESUMO
Hemispherotomy is an effective disconnection technique for the treatment of different forms of drug-resistant epilepsy due to encephalopathies with unilateral hemispheric involvement.1-8 We describe the case of a 6-year-old child affected by Rasmussen encephalitis who underwent right vertical parasagittal hemispherotomy.9 The goal of the procedure was to isolate the basal ganglia region by interrupting the interhemispheric and intrahemispheric white matter connectivity. The main surgical steps include the transcortical approach to the lateral ventricle, the posterior callosotomy, the fimbria-fornix incision, the laterothalamic vertical incision, the anterior callosotomy, the frontobasal disconnection, and the transcaudate lateral incision to the anterior temporal horn.7,10 At 10-month follow-up, the patient was seizure free with a stable left hemiparesis. The antiepileptic therapy was progressively interrupted. The video describes the main surgical steps, using both intraoperative videos and advanced three-dimensional modeling of neuroimaging pictures. Patient' parents consented to the procedure. The participants and any identifiable individuals consented to publication of his/her image. Approval from the ethics committee was acquired.
RESUMO
Craniopagus separation requires careful planning and a multi-staged surgical approach, managed by a multidisciplinary team. Despite growing experience on surgical management, the long-term restoration of the cranial defect has been rarely discussed so far. Several alloplastic materials have been proposed as effective and safe solutions for cranioplasty even for pediatric patients, allowing for bone generation, good aesthetic results, and low complication rates. We report, for the first time, on a separated craniopagus child who underwent successful implant of a tailor-made system based on the combination of calcium phosphate ceramic reinforced with a titanium mesh.

Vertical hemispherotomy is an effective treatment for many drug-resistant encephalopathies with unilateral involvement. One of the main factors influencing positive surgical results and long-term seizure freedom is the quality of disconnection. For this reason, perfect anatomical awareness is mandatory during each step of the procedure. Although previous groups attempted to reproduce the surgical anatomy through schematic representations, cadaveric dissections, and intraoperative photographs and videos, a comprehensive understanding of the approach may still be difficult, especially for less experienced neurosurgeons. In this work, we reported the application of advanced technology for three-dimensional (3D) modeling and visualization of the main neurova-scular structures during vertical hemispherotomy procedures. In the first part of the study, we built a detailed 3D model of the main structures and landmarks involved during each disconnection phase. In the second part, we discussed the adjunctive value of augmented reality systems for the management of the most challenging etiologies, such as hemimegalencephaly and post-ischemic encephalopathy. We demonstrated the contribution of advanced 3D modeling and visualization to enhance the quality of anatomical representation and interaction between the operator and model according to a surgical perspective, optimizing the quality of presurgical planning, intraoperative orientation, and educational training.
RESUMO
The outbreak of the Covid-19 pandemic has seriously affected our society. Governments have difficult situations by adopting strict and severe mitigation measures in order to contain the pandemic spreading. These decisions influenced significatively people's behavior changing their habits and routines. This study offers a statistical analysis of the incidence of the Maxillo-Facial traumas in Tuscany southern area, during the pandemic lockdown. The statistical analyzed has been obtained comparing the maxillo-facial trauma occurrence during the Italian lockdown between the 9th of March and the 18th of May 2020 in comparison with same period of the five previous years. KEY WORDS: Covid-19, Italian covid-19, Maxillofacial surgery, Maxillofacial trauma, Pandemic, Surgery management, Trauma incidence in Italy.

Meningiomas as anatomo-pathological entities were first described in the sixteenth century, but it was Harvey Cusching who in 1922 proposed to identify them with the term "meningioma". They are the most common intracranial tumors, occur between middle and late age and prefer female sex. The symptoms depend on their position with respect to the brain regions. These are mostly benign neoplasms, but there are atypical and even malignant forms. Plaque meningioma refers to a specific macroscopic aspect of the meningioma, due to diffuse dural involvement and usually with extracranial extension. We report here a case of plaque convex meningioma with typical grade I. Key Words: En plaque, Meningioma, WHO Meningioma.

BACKGROUND: Glomus tumors, or glomangiomas, are benign vascular tumors typically seen at distal extremities. These tumors differ from paragangliomas and classically present in the female population between the 4th and 5th decade. Intracranial localizations have not been described in literature in the adult population. CASE DESCRIPTION: We present a case of a 32 year-old woman with a 3 months history of progressive left-sided visual loss and headache. A pre-operative MRI showed a homogeneously enhancing lesion extending from the left cavernous sinus to middle cranial fossa at first suspected to be a cavernous sinus meningioma. Eventually, histopathological analysis concluded for a glomangioma diagnosis. Post-operative RT was also performed. CONCLUSIONS: From our experience it is very important for clinical management considering glomangiomas in differential diagnosis of a homogeneously enhancing extra axial mass. Subtotal resection followed by radiation therapy determined no recurrence of the disease up to 7 years. KEY WORDS: Glomangioma, Glomus tumor, Soft-tissue tumor.

BACKGROUND: Gunshot injuries of the viscerocranium are rarely reported. Penetrating wounds to the cranio-maxillofacial region pose a significant challenge for surgeons as they often comprise serious soft tissue, bone and cerebral defects. We present a case report of a 42-year old female with a gunshot wound to the viscerocranium after suicidal attempt. Series of image of the disease course are available. CASE DESCRIPTION: A 42-year-old female presented with gunshot wound to the viscerocranium after a suicidal attempt. At the arrival GCS was 8/15 and general examination showed the inlet wound in the submental region whereas the outlet one in the left temporal skull area. After first rescue procedures, ICP was monitored before proceeding surgically. Due to massive hemorrhage, embolization of ianternal maxillary artery was performed. Afterwards, tracheostomy, surgical reduction of multiple maxillo-facial fractures and ocular avulsion were performed. In a second time, ICP monitoring and CT scan revealed ICH signs due to intraparenchimal injures. The patient underwent to a second surgical procedure, consisting of bifrontal decompressive craniectomy. The patient was discharged on 20th post-op day to a rehabilitation center. She returned to our department after 4 months to perform a craniomaxillofacial recostruction. She presented 15 in GCS, left ptosis, left VII cranial nerve deficit, decannulated, KPS 100%. CONCLUSION: A step-to-step multidisciplinary approach both with Neurosurgeons and Maxillo-facial surgeons is mandatory in Cranial Gunshot Injuries where extensive damage is linked to a higher mortality. KEY WORDS: Cranial gunshot inuuries, Cranial reconstruction, Maxillofacial reconstruction.

OBJECTIVE: In the last 2 decades, the endoscopic endonasal approach in the treatment of clival chordomas has evolved to be a viable strategy to achieve maximal safe resection of this tumor. Here, the authors present a multicentric national study, intending to analyze the evolution of this approach over a 20-year time frame and its contribution in the treatment of clival chordomas. METHODS: Clival chordoma cases surgically treated between 1999 and 2018 at 10 Italian neurosurgical departments were included in this retrospective study. Clinical, radiological, and surgical findings, adjuvant therapy, and outcomes were evaluated and compared according to classification in the treatment eras from 1999 to 2008 and from 2009 to 2018. RESULTS: One hundred eighty-two surgical procedures were reviewed, with an increase in case load since 2009. The endoscopic endonasal transclival approach (EETA) was performed in 151 of 182 cases (83.0%) and other approaches were performed in 31 cases (17%). There was an increment in the use of EETA, neuronavigation, and Doppler ultrasound after 2008. The overall postoperative complication rate was 14.3% (26 of 182 cases) consisting of 9 CSF leaks (4.9%), 7 intracranial hemorrhages (3.8%), 5 cases of meningitis (2.7%), and 5 cerebral ischemic injuries (2.7%). Gross-total resection (GTR) was achieved in 93 of 182 cases (51.1%). Extent of resection (EOR) improved in the second era of the study. Signs and/or symptoms at presentation worsened in 27 cases (14.8%), and the Katz Index worsened in 10 cases (5.5%). Previous treatment, dural involvement, EETA, and intraoperative Doppler ultrasound correlated with GTR. Patients received adjuvant proton beam radiation in 115 of 182 cases (63.2%), which was administered more in the latter era. Five-year progression-free survival (PFS) and overall survival (OS) were 62.3% and 73.5%, respectively. GTR, EETA, proton beam therapy, and the chondroid subtype correlated with a better survival rate. The mean follow-up was 62 months. CONCLUSIONS: Through multicentric data collection, this study encompasses the largest series in the literature of clival chordomas surgically treated through an EETA. An increase in the use of this approach was found among Italian neurosurgical departments together with an improved extent of resection over time. The satisfactory rate of GTR was marked by low surgical morbidity and the preservation of patient quality of life. Surgical outcome was reinforced, in terms of PFS and OS, by the use of proton beam therapy, which was increasingly performed along the period of study.
RESUMO
BACKGROUND: Pituitary tumors are a heterogeneous group of lesions that are usually benign. Therefore, a proper understanding of the anatomy, physiology, and pathology is mandatory to achieve favorable outcomes. Accordingly, diagnostic tests and treatment guidelines should be determined and implemented. Thus, we decided to perform a multicenter study among Italian neurosurgical centers performing pituitary surgery to provide an actual depiction from the neurosurgical standpoint. METHODS: On behalf of the SINch (Società Italiana di Neurochirurgia), a survey was undertaken with the participants to explore the activities in the field of pituitary surgery within 41 public institutions. RESULTS: Of the 41 centers, 37 participated in the present study. The total number of neurosurgical procedures performed in 2016 was 1479. Most of the procedures were performed using the transsphenoidal approach (1320 transsphenoidal [1204 endoscopic, 53 microscopic, 53 endoscope-assisted microscopic] vs. 159 transcranial). A multidisciplinary tumor board is convened regularly in 32 of 37 centers, and a research laboratory is present in 18 centers. CONCLUSIONS: Diagnosing pituitary/hypothalamus disorders and treating them is the result of teamwork, composed of several diverse experts. Regarding neurosurgery, our findings have confirmed the central role of the transsphenoidal approach, with preference toward the endoscopic technique. Better outcomes can be expected at centers with a multidisciplinary team and a full, or part of a, residency program, with a greater surgical caseload.
