AIM: To identify independent risk factors and propose a predictor scoring system in chronic subdural hematoma (CSDH). MATERIAL and METHODS: Through retrospective analysis, we analyzed the data from 279 patients with CSDH from 2010 to 2020. Independent risk factors for recurrence were identified thro...

AIM: To determine hemispheric asymmetries in major white matter tracts using diffusion tensor imaging (DTI) metrics and morphometric measurements, as comprehensive multitract analyses remain limited. MATERIAL and METHODS: Diffusion MRI data from 102 healthy adults enrolled in the Human Connectome Pr...

AIM: To present the long-term follow-up results of dry-field maneuver in neuroendoscopy. MATERIAL and METHODS: The dry-field maneuver has been used in our clinic since 2012, leading to a retrospective review of patients undergoing neuroendoscopic procedures from 2012 to 2024. RESULTS: The dry-field ...

AIM: To evaluate the relationship between optic nerve sheath diameter (ONSD) and intracranial pressure (ICP) in patients with acute ICP elevation controlled through external ventricular drainage (EVD). MATERIAL and METHODS: In this prospective observational study, simultaneous measurements of right ...

AIM: To retrospectively analyze infants treated with early surgical management using the simple excision technique and discusses the outcomes in light of the existing literature. MATERIAL and METHODS: Ten infants with OCH who underwent surgery were included in this study. The following parameters we...

AIM: To investigate the effects of sodium nitrite on spinal cord development in early-stage chick embryos. MATERIAL and METHODS: Sixty specific-pathogen-free fertile Leghorn-type eggs at Day 0 of incubation were used. Group 1 (control) received saline, Group 2 (low-dose) was administered 0.0042 mg o...

AIM: To compare the regional tissue oxygen saturation under general, spinal, and epidural anesthesias during the posterior lumbar discectomy procedures performed in the prone position. MATERIAL and METHODS: A total of 90 patients with an American Society of Anesthesiologists score I-III were evaluat...

AIM: To present a single-center experience with posterior C1–C2 fixation for atlantoaxial instability, emphasizing an anatomy-driven approach to C2 anchorage selection, construct strategy, complications, and clinical outcomes. MATERIAL and METHODS: We retrospectively reviewed 45 patients who underwe...

AIM: To analyze the efficacy and safety of Gamma Knife radiosurgery (GKRS) in the management of thyroid cancer brain metastases (TCBM). MATERIAL and METHODS: This retrospective study analyzed patients who underwent GKRS for TCBM at two centers between September 2005 and February 2025. Patients’ clin...

AIM: To analyze the safety and effectiveness of the minimally invasive endoscopic approach in the treatment of large intraventricular tumors. MATERIAL and METHODS: We retrospectively reviewed the demographic, radiological, and surgical data of 8 patients who were operated on using the endoscope-plus...

AIM: To investigate the preoperative, early and late postoperative differences in the anterior callosal angle, lateral and third ventricle shapes of patients with pituitary macroadenoma operated via the transsphenoidal approach. MATERIAL and METHODS: Shape data of the third and lateral ventricles we...

AIM: To establish a nomogram model of Ki-67-positive grade 4 diffuse gliomas that can predict the survival rate of patients and has certain guiding values that are useful in treatment. MATERIAL and METHODS: Data from 146 patients with Ki-67-positive grade 4 diffuse gliomas was retrospectively obtain...

Grynfeltt-Lesshaft hernia is a rare type of posterolateral abdominal wall hernia that may be either congenital or acquired. Only a few cases have been reported following surgical procedures. The risk of herniation increases after surgeries involving this region due to the weakening of the musculofas...

Stereotactic radiosurgery (SRS) is an established treatment for vestibular schwannoma, offering high tumor control rates and a favorable safety profile. SRS-induced facial palsy is typically a late-onset complication, with acute-onset cases being exceedingly rare. We report the case of a 42-year-old...

Using intravenous contrast, photon-counting computed tomography angiography (PCCT-A) provides detailed images of intracranial vessels. We report a case in which PCCT-A revealed a 1.5 mm aneurysm at the bifurcation of the middle cerebral artery that was not seen on magnetic resonance angiography. Thi...

Rapid formation and recurrence of aneurysms accompanied by severe arterial stenosis following radiation therapy (RT) for nasopharyngeal carcinoma (NPC) is an uncommon clinical phenomenon. We present the case of a 51-year-old man who developed subarachnoid hemorrhage years after undergoing RT for NPC...

AIM: Chronic subdural hematoma (cSDH) is a common neurosurgical condition in elderly patients, frequently associated with trauma, anticoagulant use, and chronic comorbidities. While surgical evacuation and now middle meningeal artery embolization remain the predominant treatment options, endoscopic-...
