    Abstract Background: Extramedullary anterior cervical canal tumors can be challenging lesions to reach. The posterolateral trans dentate approach offers an alternative route.
    Method: Classic posterior laminoplasty is done to expose the medulla; the dentate ligament is identified as a fibrous structure running from the lateral pial surface of the medulla to the lateral dura between nerve roots spaces. Once the ligament is cut, the medulla can be gently rotated to access the anterior cervical canal. Intraoperative neurophysiological stimulation is mandatory.
    Conclusion: This approach allows a safe route, without the need for corpectomies. It should be considered especially in children where multilevel corpectomies could be challenging.

    Abstract Background: CNS ganglioneuroblastoma in an extremely rare embryonal tumour, specifically in the pediatric population. Bad prognosis is documented due to aggressiveness and absence of protocolized treatment at the moment.
    Clinical description: We present the case of a 5-year-old boy who presented with sudden loss of consciousness. CT scan was performed showing a large posterior fossa lesion with several intraventricular focal lesions, suggesting metastases, the largest one located inside the III ventricle. The patient underwent a posterior fossa resection of the lesion and a subtotal resection of the III ventricle lesion, with adjuvant chemotherapy. The evolution was poor and the patient finally died 3 months after diagnosis.
    Conclusion: Ganglioneuroblastoma is extremely likely to recur quickly and extensively. There is little knowledge about treatment options but is documented that gross total resection followed by adjuvant radiotherapy and chemotherapy is the best management in these patients.

    Abstract Objective: Endoscopy-assisted craniosynostosis surgery (EACS) yields excellent surgical outcomes by minimizing blood loss, operative time, and hospital stays. Postoperative helmet therapy (PHT), commonly employed for head shape correction, involves frequent adjustments, potential complications, and high costs. Given the rising cost of helmet therapy, reduced insurance coverage, and limited availability in low- and middle-income countries, understanding success rates without helmet use is crucial. The present study analyses the anthropometric results of the first EACS series without PHT.
    Methods: A retrospective analysis of a single-center series involving 90 consecutive patients who underwent EACS without PHT from 2012 to 2022 was conducted, with a follow-up exceeding 3 years. The study exclusively included patients with nonsyndromic isolated sagittal synostosis, with 33 meeting the criteria. Craniometric measurements were obtained from preoperative, 1-year postoperative, and the latest computed tomography scans. For isolated sagittal synostosis cases, the cephalic index (CI) was calculated (CI >75 for excellent results, CI 70-75 for good results, and <70 for poor results). Collected data encompassed patient sex, age, and follow-up time.
    Results: The mean age was 84.8 ± 45.3 days (2.79 ± 1.49 months) within a range of 3-172 days. The preoperative mean CI was 68 ± 42, increasing to 76 ± 6 1 year postoperatively (mean difference +8 ± 6.3; P = 0.0001). Seventy-one percent of patients achieved excellent results, 23% good (CI = 70-75), and 6% poor. Reintervention was unnecessary.
    Conclusions: EACS without PHT demonstrates favorable anthropometric results, cost reduction, and simplified postoperative management.

    Abstract Background: Surgical decompression to the optic-chiasmatic region in craneofacial fibrous dysplasia (CFD) must be performed safely to improve or stabilize visual loss.
    Method: We describe a technical nuance when facing on a huge, deformed skull with potentially imbricated dura mater. Craniectomy was performed in concentric arches allowing to expose surgical field and elevated step by step. Bilateral micro-decompression was performed after without difficulties.
    Conclusions: Decompressing both optic nerves using this technique is safe and relatively simple to perform.

    Abstract Background: The presigmoid approach classically includes the ligature and section of the superior petrosal sinus to get a wider visibility window to the antero-lateral brainstem surface. In some cases, the separation of this venous structure should not be performed.
    Method: We present our experience getting safely to a pontine cavernous malformation through a conventional mastoidectomy presigmoid approach preserving an ingurgitated superior petrosal sinus because the association with an abnormal venous drainage of the brainstem.
    Conclusions: When sectioning the superior petrosal sinus in classical presigmoid approaches is contraindicated, its preservation could also offer good surgical corridors to get to small-medium anterior and lateral brainstem cavernous malformations.

    Abstract Split cord malformation (SCM) is a term used for all double spinal cords. It represents 3.8%-5% of spinal dysraphisms. Pang et al.'s embryological theory proposes the formation of an "accessory neurenteric canal" that communicates with the yolk sac and amnion. To the authors' knowledge, only three cases of diastematobulbia (basicranial SCM) associated with a spur or dermoid have been reported in the literature.The case patient is a newborn girl with an occipitocervical meningocele and dermal sinus associated with an anomaly of notochordal development in the transition between the medulla oblongata and the spinal cord (diastematobulbia) without a bony septum or dermoid cyst. The patient also has agenesis of the atlas and an absence of corticospinal tract decussation. This patient underwent reconstruction of the occipital meningocele and dermal sinus excision.To the authors' knowledge, this is the first described case of type II diastematobulbia (basicranial SCM), without a dermoid cyst. The authors analyzed the embryological errors present in the case patient and considered the option of further surgical treatment depending on the evolution of the patient's condition. At the time of this report, the patient had shown normal psychomotor development. However, this fact may only be due to the patient's young age. Considering that after initial untethering the patient remained clinically asymptomatic, conservative and close surveillance has been and continues to be the proposed treatment.

    Abstract Introduction: Posthemorrhagic hydrocephalus in preterm infants is a serious entity related to high mortality and morbidity. Neuroendoscopic lavage (NEL) is a suitable alternative for the management of this pathology. However, as with every endoscopic technique, it requires some experience and several cases to master.
    Methods: We present a descriptive study of some technical nuances, tips, and tricks that have been learned in the last 8 years with over a hundred NELs performed in preterm infants. These variations are classified into 3 categories according to their temporal relationship with the surgical procedure: preoperative stage, intraoperative stage, and postoperative stage. We include a brief description of each one and the reasons why they are included in our current clinical practice.
    Results: Twenty tips and pearls were described in detail and are reported here. Preoperative, intraoperative, and postoperative variations were exposed and related to the most frequent complications of this procedure: infection, cerebrospinal fluid leak, and rebleeding.
    Conclusions: NEL is a useful technique for the management of germinal matrix hemorrhage in preterm infants. These technical nuances have improved the results of our technique and helped us to prevent complications related to the procedure.

    Abstract Background: Endoscopic approaches for craniosynostosis are a growing field in pediatric neurosurgery. In metopic synostosis, previous reports for complete fronto-orbital remodeling have proposed an intervention with multiple incisions (bregmatic, tarsal, and preauricular) to open frontonasal and frontoethmoidal synostotic sutures, and orbital roof.
    Methods: We propose a technique to complete all these osteotomies with a unique incision anterior to the bregmatic fontanel under 3D endoscopic vision, and review possible complications, limits, and pitfalls.
    Conclusions: Under endoscopic assistance, a complete fronto-orbital remodeling could be completed with a unique incision without mayor drawbacks.

    Abstract Purpose: Due to the generalization of new microsurgical equipment, intraoperative fluorescence techniques have extended in neurosurgical practice, mainly in neurovascular and neuro-oncology patients. The aim of identifying pathological tissue and also differentiating from the normal brain helps neurosurgeons to approach other kinds of intracranial entities such as infections.
    Methods: It is described in the case of an 11-year-old patient who underwent a subdural empyema by performing a craniotomy and evacuation of the purulent collection. After a non-optimal evolution, a frontobasal meningoencephalitis was assessed with cerebral involvement and associated intracranial hypertension. Indocyanine green (ICG) was used in reintervention for demonstrating a great damage of cortical vascularization around the infected area as well as fluorescein (FL), which identified a large area of avascularized tissue.
    Results: Both techniques allowed a selective excision of the affected brain parenchyma while preserving viable parenchymal areas. Radiological evolution and clinical outcome were good.
    Conclusions: The identification of vascular patterns in brain lesions and the recognition of viable or necrotized tissues are suitable for a selective resection of the parenchyma, minimizing morbidity. Clinical outcome is related to a safe and effective management of inflammatory and infectious processes.
