Osteoplastic Pterional Craniotomy: Success Rate of Surgery in Patient Aspect.

Aim: To evaluate the effect of osteoplastic pterional craniotomy on temporal hollowing and its sequelae.

Material And Methods: A total of 97 patients who underwent pterional craniotomy for an aneurysm were analyzed retrospectively. Of these 97 patients, 63 underwent surgery via the conventional pterional approach and 34 underwent surgery via the osteoplastic pterional approach.

Magnetic Resonance Imaging Evaluation of Multifidus Muscle in Patients with Low Back Pain after Microlumbar Discectomy Surgery.

Cross-sectional area (CSA) and signal intensity ratio (SIR) of the multifidus muscle (MFM) on magnetic resonance imaging (MRI) was used to evaluate the extent of injury and atrophy of the MFM in patients with negative treatment outcomes following microlumbar discectomy (MLD). Negative treatment outcome was determined by pain score improvement of <50% compared to baseline. Patients in groups 1, 2, and 3 were evaluated at <4 weeks, 4-24 weeks, and >24 weeks postoperatively, respectively.

Spinal Schwannomas: A Proposal for a New Classification to Aid Surgical Planning.

Background The treatment of spinal schwannomas, which is the most common nerve sheath tumor, is total microsurgical resection. The localization, size and relationship with the surrounding structures of these tumors are crucial in terms of preoperative planning. A new classification method is presented in this study for the surgical planning of spinal schwannoma.

Use of 3-Dimensional Modeling and Augmented/Virtual Reality Applications in Microsurgical Neuroanatomy Training.

Background: Understanding the microsurgical neuroanatomy of the brain is challenging yet crucial for safe and effective surgery. Training on human cadavers provides an opportunity to practice approaches and learn about the brain's complex organization from a surgical view. Innovations in visual technology, such as virtual reality (VR) and augmented reality (AR), have immensely added a new dimension to neuroanatomy education.

The possible effects of sodium fluoroscein to primary cell culture sampling in glioblastoma surgery.

•FL increases beta-galactosidase activity in GBM cell cultures.•FL cause a decrease in GBM cell numbers.•Sampling in GBM cell culture should be performed before using FL.

Surgical Treatment of Spinal Arachnoid Cysts: Cyst Excision or Fenestration?

Aim: Arachnoid cysts in the spinal canal account for 1%-3% of all spinal canal lesions. There is no consensus on surgical treatment yet. Dural defect repair is crucial in surgical treatment patients with an extradural component.

Factors Associated with Nontraumatic Spontaneous Subdural Hematomas in Pediatric Patients.

Objective: In our study, we aimed to summarize the etiology of subdural hematoma that was not traumatic and required operation in pediatric patients. The subdural hematoma characteristics, possible etiologies, and treatment, as well as the patient outcomes, were analyzed.

Methods: A retrospective examination was made of pediatric patients with subdural hematoma who were operated on at Ümraniye Training and Research Hospital.

Contralateral vs. Ipsilateral Approach to Superior Hypophyseal Artery Aneurysms: An Anatomical Study and Morphometric Analysis.

Introduction: Surgical clipping of superior hypophyseal artery (SHA) aneurysms is a challenging task for neurosurgeons due to their close anatomical relationships. The development of endovascular techniques and the difficulty in surgery have led to a decrease in the number of surgical procedures and thus the experience of neurosurgeons in this region. In this study, we aimed to reveal the microsurgical anatomy of the ipsilateral and contralateral approaches to SHA aneurysms and define their limitations via morphometric analyses of radiological anatomy, three-dimensional (3D) modeling, and surgical illustrations.

Can Posterior Midline Approach Provide Adequate Exposure for All Craniovertebral Junction Tumors?

Introduction: The surgical treatment of craniovertebral junction (CVJ) lesions remains a difficult process requiring advanced experience. The aim of this study was to present our experience and the clinical results of a posterior and posterolateral approach used for CVJ lesions in our clinic, and to discuss these in light of current literature.

Methods: Clinical, radiologic, and surgical aspects of 30 patients with CVJ tumors were retrospectively evaluated.

Role of Spinal Instability Neoplastic Score in Management of Spinal Plasmacytoma.

Objective: The decision to perform surgery in cases of spinal plasmacytoma (SP) is controversial. This study aimed to evaluate the reliability of the Spinal Instability Neoplastic Score (SINS) in evaluation of spinal instability in patients with SP.

Methods: Clinical and radiological characteristics of 10 patients with SP were retrospectively evaluated.

Reattachment of the Temporalis Muscle After Frontoorbital Advancement in Craniosynostosis Surgery.

Craniosynostosis surgery may result in temporal hollowing occasionally. Overexpansion of the normal side and undergrowth of the affected side exacerbate the problem in unilateral cases (like unicoronal synostosis). Temporalis muscle lies in the temporal fossa, and it is usually severed or detached from its origin in order to reach the lateral aspect of the fronto-orbital bar.

TRAIL-conjugated silver nanoparticles sensitize glioblastoma cells to TRAIL by regulating CHK1 in the DNA repair pathway.

Objectives: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively triggers apoptosis in cancer cells, but not in normal cells. Resistance of glioblastoma cells to TRAIL is a major obstacle for successful clinical treatment of TRAIL. Thus, there is an essential requirement for novel approaches to sensitize TRAIL resistance.

Surgical Anatomy of the Labyrinthine and Subarcuate Arteries and Clinical Implications.

Objective: To study the surgical anatomy of the labyrinthine artery (LA) and the subarcuate artery (SA), their anatomic relationships, and clinical implications, as injury of the LA can result in hearing loss.

Methods: Ten formalin-fixed, latex-colored specimens were studied (20 sides). After retrosigmoid craniotomy and neurovascular dissection under microscopic magnification, 4-mm 0° and 30° endoscopic lenses were used to improve visualization.

Spontaneous cervical epidural hematoma with hemiparesis mimicking cerebral stroke.

Aim. Spontaneous cervical epidural hematoma (SCEH) is defined as an epidural hematoma that does not have an etiological explanation. The most common site for SCEH is cervicothoracic area.
