Personal protective equipment (PPE) use is recommended in all surgeries. The authors have experienced varying degrees of field of view (FOV) loss under the surgical microscope with different PPE.

Women in Neurosurgery: Gender Differences in Authorship in High-Impact Neurosurgery Journals through the Last Two Decades.

Objective: Despite common gender disparities in authorship across the vast majority of specialties, the presence of a similar lack of equality in neurosurgery literature is not published yet. Therefore the authors examined the changes in representation of women among the first and senior (last) authors of original articles in high-impact neurosurgical journals between 2003 and 2018.

Methods: Data regarding women proportions among the first and senior authors were collected from the issues of Neurosurgery and Journal of Neurosurgery published in 2003, 2008, 2013, and 2018.

Hyperbaric oxygen therapy in the treatment of malign edema complication after arteriovenous malformation radiosurgery.

A 16-year-old female patient with headache was admitted to our hospital. Radiological examination showed a Spetzler-Martin Grade III arteriovenous malformation (AVM) located at the left frontal lobe. Volume-staged stereotactic radiosurgery (SRS) treatment performed in two fractions at three-month intervals and post-procedural period were uneventful.

Management of Neonatal Facial Paralysis due to Cerebellopontine Angle Arachnoid Cyst: A Case Report.

Arachnoid cysts are benign, cerebrospinal fluid-filled collections that can be located in the brain or spinal cord. Arachnoid cysts form approximately 1% of all intracranial lesions. They are accepted as arachnoid developmental anomaly and arise from membrane splitting or duplication.

Can the Etiopathogenesis of Chiari Malformation Be Craniocervical Junction Stabilization Difference? Morphometric Analysis of Craniocervical Junction Ligaments.

Objective: The craniocervical junction permits a certain amount of mobility for the cervical spine. The biomechanical properties of occipital bone-atlas joint mainly depend on the bony structure, and atlas-axis joint biomechanical properties mainly depend on ligamentous structure. The underlying etiologic factor of Chiari malformation (CM) is debatable.

Clinical and surgical outcomes of upper lumbar disc herniations: a retrospective study.

Background/aim: Upper lumbar disc herniation (LDH), generally involving L1?L2 and L2?L3 level herniation, is less common than lower LDH and, in this retrospective study, the clinical and radiological findings of patients who suffered from upper LDH and were operated on due to this pathology were reviewed. Materials and methods: Data regarding neurological and radiological findings of patients operated on between January 2005 and December 2013 were retrospectively collected. During this period, 3494 patients had surgery for LDH, and 129 of these patients had disc herniation at the upper levels.

Intramedullary dermoid cyst infection mimicking holocord tumor: should radical resection be mandatory?-a case report.

Background: Dermoid cysts are benign lesions which contain epidermal and dermal elements. Dermoid cysts usually contain a dermal sinus tract but this is not mandatory. Dermoid cysts can manifest by spinal cord infection without a dermal sinus tract.

Retrospective Analysis of 449 Intracranial Meningioma Patients Operated Between 2007 and 2013 at a Single Institute.

Aim: Meningioma literature has many large surgical case series, which have been references of text books and neurosurgical practice. Many of those series were published when stereotactic radiosurgery (SRS) was not so common or these series were in terms of World Health Organization (WHO) 2000 classification. In this study, we aimed to make an update to the current literature using WHO 2007 classification system.

Bilateral Optic Pathway Ganglioglioma: The Fifth Case in the Literature.

Gangliogliomas are mixed tumors which contain both glial and neuronal elements. The optic pathway is a very rare location for gangliogliomas, with less than 23 cases reported in the literature. Bilateral involvement of the entire optic pathway was reported in only 4 cases before.

Trigeminal neuralgia associated with cerebellopontine angle lipoma in childhood.

Cerebellopontine angle lipomas are rare and more rarely associated with trigeminal neuralgia especially in childhood. Medical treatment provides relief from the pain; however, the effect may not be permanent. Surgical treatment is associated with a high morbidity rate; therefore, surgery should be considered only in intractable cases.

Direct venous spinal reabsorption of cerebrospinal fluid: a new concept with serial magnetic resonance cisternography in rabbits.

Object: For nearly 100 years it has been believed that the main reabsorption of CSF occurs in arachnoid projections into the superior sagittal sinus, but a significant number of experiments and cases conflict with this hypothesis. According to recently published studies, CSF is permanently produced and absorbed in the whole CSF system. Clusters of arachnoidal villi, which are speculated to have a role in the reabsorption of CSF, have recently been revealed in the dorsal root of the spinal nerves.
