Expanded endoscopic endonasal approach to the inframeatal area: anatomic nuances with surgical implications.
Background/Objective: The inframeatal area represents a challenging region for skull base surgeons. Various surgical corridors have been described to access this area and are frequently used in combination. Recent studies describe the expanded endoscopic endonasal approach (EEA) as an established route for midline regions particularly medial to the internal carotid arteries (ICA). We sought to evaluate the accessibility, maneuverability and freedom of movement of the expanded endoscopic endonasal approach to the inframeatal region. (Source: World Neurosurgery)

Clinical and Radiological Features of Osteoporotic Spine Fracture with Delayed Neurological Compromises
Osteoporotic spine fractures (OSFs) with delayed neurological compromises (NC) have been increasingly reported. Although several studies have addressed that the pathomechanism of NC involves nonunion and segmental instability, the risk factors still remain unclear. Therefore, the purpose of this study is to assess the radiological and clinical features of OSFs with delayed NC. (Source: World Neurosurgery)

A novel malleable continuous suction tube made of ultrathin stainless-steel foil enclosed between two ultrafine mesh layers: technical note
Bloodless dry fields are indispensable for successful and safe neurosurgical operations using microscopes. Appropriate irrigation and suction systems are needed to obtain clear surgical fields. We invented a novel malleable continuous suction tube to address this need. (Source: World Neurosurgery)

Intracranial meningeal Rosai –Dorfman disease mimicking multiple meningiomas: Three case reports and a literature review
Rosai-Dorfman disease (RDD) is a benign, self-limiting and non-neoplastic histiocytic proliferative disorder with a poorly defined pathogenesis. Central nervous system involvement is extremely rare, particularly in cases with multiple intracranial masses. There is no consensus on the optimal treatment and management of RDD.

Proton Magnetic Resonance Spectroscopy (H1-MRS) Study of the Ketogenic Diet on Repetitive Mild Traumatic Brain Injury in Adolescent Rats and Its Effect on Neurodegeneration
A ketogenic diet (KD) improves cellular metabolism and functional recovery after moderate-to-severe traumatic brain injury. Here, we evaluated the changes of neurochemical metabolites after KD therapy for repetitive mild traumatic brain injury (rmTBI) and its possible role in neurodegeneration.

Susceptibility-weighted imaging of deep venous congestion in petroclival meningioma
Protecting the venous drainage route in cases with petroclival meningioma (PCM) is important, as PCM progression, as well as a transpetrosal approach, disturbs the venous drainage route; the transpetrosal approach is associated with a superior petrosal sinus venous route impairment risk. The intracranial veins, which do not have a venous valve and have anatomical anastomosis, form a bypass route. It is unknown whether venous congestion occurs in PCM cases.

Intracranial Arterial Tortuosity according to the Characteristics of Intracranial Aneurysms
and Purpose: Intracranial aneurysm (IA) is the leading cause of subarachnoid hemorrhage. The pathomechanisms of IA are poorly understood but can be related to arterial tortuosity resulting from underlying systemic factors leading to arterial wall weakening. We aimed to analyze the tortuosity of the intracranial artery in an IA cohort, hypothesizing that the tortuosity of intracranial arteries will differ depending on the characteristics of the IA.

Transclival Venous Circulation: An Anatomical Study
The clivus is a small and central area of the basal cranium with limited surgical access and high morbidity associated with pathologies of its surrounding structures. Therefore, a thorough knowledge and understanding of the anatomy in this region is crucial for the success treatments and interpretation of imaging. As to our knowledge, there is no extant cadaveric examination of the transclival veins, the present study was performed. (Source: World Neurosurgery)
