Effect of clival bone growth on the localization of the abducens nerve at the petroclival region: a postmortem anatomical study.

Purpose: To investigate the effect of the clival bone pattern on the abducens nerve (AN) localization in the petroclival region between the Pediatric and Adult Groups.

Methods: This study used 12 pediatric and 17 adult heads obtained from the autopsy. The length and width of the clivus and the length of the petrosphenoidal ligaments (PSLs) were measured.

Comparison of Thalamus Volume on Magnetic Resonance and Cadaveric Section Images.

Aim: To measure and to compare the volume of thalamus using magnetic resonance imaging (MRI) and the anatomical sections.

Material And Methods: In this study, 13 brain specimens were used. First, the images were taken in 3 mm sections on MRI, the thickness of the thalamus was measured.

Analysis of biochemical laboratory values to determine etiology and prognosis in patients with subarachnoid hemorrhage: a clinical study.

Objectives: The aim of this study was to establish prognostic and predictive markers in patients with subarachnoid hemorrhage (SAH) using simple laboratory methods.

Methods: A retrospective examination was made of patients with SAH diagnosed secondary to isolated head trauma, isolated anterior communicating artery aneurysm rupture, and angiography-negative SAH. Age, gender, Glasgow Coma Scale (GCS) scores, and Fisher's grade scores, Glasgow Outcome Scale (GOS) scores, leukocyte count, neutrophil count, lymphocyte count, platelet count, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio results (PLR) were evaluated.

Research on the Effects of Levetiracetam in Spinal Cord Injury Model in Rats: An Experimental Study.

Despite advances in spinal biomechanic research, surgical techniques, and rehabilitation processes, no significant improvement has been identified in the treatment of spinal cord injury (SCI) and neurological recovery. This study was designed to investigate the potential therapeutic effects of methylprednisolone and levetiracetam on SCI. In this study, 42 male Wistar Albino rats, each weighing 300-350 g, were separated into three main groups: control group, acute and subacute stage groups.

An Evaluation of the Quality of Sleep Before and After Surgical Treatment of Patients with Cervical Disc Herniation.

Objective: It has been reported in recent studies that 50-80% of patients with cervical disc hernia have concomitant sleep disorders. The aim of this study was to evaluate the quality of sleep before and after surgical treatment in patients with cervical disc hernia and to assess the effects on treatment.

Methods: The study included 32 patients performed discectomy and fusion with an intervertebral cage through the right anterior cervical approach.

Sonoelastographic evaluation of the sciatic nerve in patients with unilateral lumbar disc herniation.

Objective: The aim of this study was to compare strain elastography (SE) and shear wave elastography (SWE) findings of the sciatic nerve in patients with unilateral lumbar disc herniation (LDH) and healthy control subjects.

Materials And Methods: The study group included patients with complaints of unilateral sciatica for 3-12 months, with foraminal stenosis due to one level of LDH (L4-L5 or L5-S1). An age- and gender-matched control group was formed of healthy subjects.

Evaluation of posterior clinoid process pneumatization by multidetector computed tomography.

In the present study, we investigated the types and ratio of posterior clinoid process (PCP) pneumatization in paranasal sinus multidetector computed tomography (MDCT). Paranasal MDCT images of 541 subjects (227 males, 314 females), between 15 and 65 years old, were included into the study. Pneumatization of anterior clinoid process and pneumatization types (I, II, or III) were evaluated in the males and females.

Investigation of the calcification at the petroclival region through Multi-slice Computed Tomography of the skull base.

Objectives: The aim of this paper was a retrospective investigation of calcification at the petroclival region using Multi-slice Computed Tomography (MSCT).

Methods: One hundred thirty skull bases were reviewed. The images were acquired with a 64 slice CT (MSCT).

The Presence of Clival Foramen Through Multidetector Computed Tomography of the Skull Base.

Objectives: Technological advancements in the diagnostic radiology recently permitted reviewing the normal anatomy through multidetector computed tomography (MDCT) imagination. The aim of this paper is retrospectively investigation of the clival foramen and canal through MDCT.

Materials And Methods: One hundred eighty-six MDCT scans were reviewed.

Spinal gas accumulation causing lumbar discogenic disease: a case report.

Vacuum disc phenomenon is seen frequently with degenerative disc disease and is characterized by the collection of gas in the disc space. Although the accumulation of gas within the disc space does not have clinical significance, symptoms may develop when occurring within the spinal canal. We present a 60-year-old female patient with low back and left leg pain occurring for 3 months before admission to our clinic.

Poloxamer-188 and citicoline provide neuronal membrane integrity and protect membrane stability in cortical spreading depression.

Under pathological conditions such as brain trauma, subarachnoid hemorrhage and stroke, cortical spreading depression (CSD) or peri-infarct depolarizations contribute to brain damage in animal models of neurological disorders as well as in human neurological diseases. CSD causes transient megachannel opening on the neuronal membrane, which may compromise neuronal survival under pathological conditions. Poloxamer-188 (P-188) and citicoline are neuroprotectants with membrane sealing properties.

Importance of the perforating arteries in the proximal part of the PICA for surgical approaches to the brain stem and fourth ventricle--an anatomical study.

Objective: The purpose of this study is to examine the perforating arteries (PAs) in the proximal part of the posterior inferior cerebellar artery (PICA) for surgical approaches to the brain stem and fourth ventricle, and to stress their importance in microsurgical procedures.

Methods: Twenty-six adult cadaver obtained from routine autopsies were used. During the examination, the PAs and the segmental structure of the proximal part of the PICAs and their relation to the neighbouring anatomical structures were demonstrated.

Subarachnoid, subdural and interdural spaces at the clival region: an anatomical study.

Aim: We aimed to show the significance of the anterior pontine membrane as a determining structure between the subdural and subarachnoid space in the clival region.

Material And Methods: Five adult cadaver heads and five cerebral hemispheres were used. The skull vault and hemipheres were removed by sectioning through the pontomesencephalic junction.

Symptomatic spontaneous pneumocephalus after spinal fusion for spondylolisthesis.

Symptomatic spontaneous pneumocephalus after a spinal fusion for spondylolisthesis without injury to the dura mater is rare. There are only a few reports of tension pneumocephalus after spinal operations published in English. We present a patient who developed tension pneumocephalus without recognised dural injury during surgery.
