Salvage posterior atlantoaxial fixation techniques: A retrospective study.

Object: Since the atlantoaxial region have critical neurovascular anatomy and limited bone surface for fusion, the application and choice of salvage fixation techniques are highly important. To discuss alternative posterior atlantoaxial fixation surgery techniques.

Methods: We retrospectively surgical records of 22 patients that posterior atlantoaxial fixation techniques were applied.

Effects of Modified Osteoplastic Pterional Craniotomy on Temporal Muscle Volume and Frontal Muscle Nerve Function.

 Pterional craniotomy is a surgical approach frequently used in aneurysm and skull base surgery. Pterional craniotomy may lead to cosmetic and functional problems, such as eyebrow drop due to facial nerve frontal branch damage, temporal muscle atrophy, and temporomandibular joint pain. The aim was to compare the postoperative effects of our modified osteoplastic craniotomy with classical pterional craniotomy in terms of any change in volume of temporal muscle and in the degree of frontal muscle nerve damage.

Lateral transorbital approach: an alternative microsurgical route for supratentorial cerebral aneurysms.

Objective: Transorbital approaches for neurosurgery have recently attracted attention and several anatomical studies have aimed to improve these techniques, but significant deficiencies in clinical practice remain, especially for aneurysm surgery. The authors present an alternative microsurgical route and the results of an analysis of patients with intracranial aneurysms who underwent a lateral transorbital approach (LTOA) using lateral orbito-zygoma-sphenotomy (LOZYGS).

Methods: The clinical and surgical results of a series of 54 consecutive patients with 1 or more aneurysms who underwent surgery via LTOA are reported.

oil and thymoquinone reduce oxidative stress in the brain tissue of rats exposed to total head irradiation.

To evaluate the antioxidant and radio-protective effects of oil (NSO) and thymoquinone (TQ) on radiation-induced oxidative stress in brain tissue. Fifty-four Sprague-Dawley rats were divided into six groups to test the radio-protective effectiveness of oil and thymoquine administered by either orogastric tube or intraperitoneal injection. Appropriate control groups were also studied.

Tegmento-vermian dysplasia: radiologic features of a novel described anatomic variation.

Here we present the incidental radiological findings of a case that has a huge pontine tegmental cap orienting posteriorly towards the fourth ventricle and continues with the inferior vermis, accompanied by a midline anterior midbrain cleft. Having knowledge about this variation will prevent a misdiagnosis of a posterior fossa tumor and eventual unnecessary biopsy or operation.

Cavernous hemangiomas of the third ventricle: Alternative surgical routes in two cases.

Cavernous Hemangiomas (CH) arise from any part of the cerebrum. Intraventricular lesions are rare and pure third ventricular localization is rare for CHs. Cavernomas of the ventricles may present with bleeding or signs associated with hydrocephalus.

The surgery and early postoperative radicular pain in cases with multifocal lumbar disc herniation.

Persistence of postoperative radicular pain after surgery for multifocal disc herniation (MFDH) is a clinical problem. This study aims to evaluate the effects of a combined treatment approach compared with unilateral stabilization on early postoperative radicular pain in patients with MFDH.Age, sex, level of operation, clinical findings, and radicular pain visual analogue scale (VAS) scores before surgery in the early postoperative period and at 3 months after surgery were retrospectively reviewed for 20 cases of multifocal lumbar disc herniation.

Relationship of biological factors to survival in spinal gunshot injuries.

Background: Gunshot injuries are the third leading cause of spinal injuries, after falls from a significant height and traffic accidents. Severity of spinal damage from gunshot injury depends upon certain mechanical and biological factors. The aim of the present study was to investigate the effect of biological factors on survival in cases of spinal gunshot injury.

Outcomes and demostration of cranial firearm injuries: A multicenter retrospective study.

Background: Cranial firearm injuries (CFAI) are associated with significant morbidity and mortality.This study was aimed to determine the factors affecting mortality of CFAI cases managed in our institution by a retrospective analysis of CT scans and clinical data.

Methods: This multicenter retrospective study examined two hundred and nineteen patients presenting to neurosurgery clinics after CFAI between January 2012 and November 2014.

Removal of large hydatid cysts with balloon-assisted modification of Dowling's method: technical report.

Background: Delivery of hydatid cysts, especially large ones, without rupture is very important and there is still no 100% successful method.

Methods: After the hydatid cyst was reached, starting near the surface working around the cyst toward the base, a Foley probe was advanced and, in the region of desired dissection, the balloon of the Foley probe was inflated, and adhesion bands were freed to allow dissection.

Conclusions: We believe our balloon-aided dissection technique is a method that increases the chances of delivering hydatid cysts, with no calcification and secondary infection, without rupture.

Spondylodiscitis: evaluation of patients in a tertiary hospital.

Introduction: Spondylodiscitis (SD) is an uncommon but important infection. The aim of this work was to study the risk factors, bacteriological features, clinical, laboratory and radiological findings of SD, and to shed light on the initial treatment.

Methodology: A total of 107 patients who underwent treatment for SD were evaluated.

Upper cervical spinal cord gunshot injury without bone destruction.

Introduction: This report describes a rare case of the gunshot injury of the spine and spinal cord.

Presentation Of Case: A rare case of the bullet lodged intra-durally in the upper cervical region without damaging the vertebrae or the spinal cord. The bullet was removed as microneurosurgical and duraplasty was performed.

Radiation-modifying abilities of Nigella sativa and thymoquinone on radiation-induced nitrosative stress in the brain tissue.

To investigate Nigella sativa oil (NSO) and Thymoquinone (TQ) for their antioxidant effects on the brain tissue of rats exposed to ionizing radiation. Fifty-four male albino Wistar rats, divided into six groups, were designed as group I (normal control group) did not receive NSO, TQ or irradiation; group II (control group of TQ) received dimethyl sulfoxide and sham irradiation; group III (control group of NSO) received saline and sham irradiation; group IV (irradiation plus NSO group) received both 5 Gray of gamma irradiation to total cranium and NSO; group V (irradiation plus TQ group) received both irradiation and TQ; group VI (irradiation alone group) received irradiation plus saline. Alterations in nitric oxide (NO·) and peroxynitrite (ONOO(-)) levels, and nitric oxide synthase (NOS) enzyme activity were measured by biochemical methods in homogenized brain tissue of rats.
