Optic nerve sheath diameter measurement for prediction of postdural puncture headache.

Purpose: Intracranial hypotension due to cerebrospinal fluid leak is mainly the causal factor for the pathophysiology of postdural puncture headache (PDPH). In this study, we aimed to evaluate the effectiveness of optic nerve sheath diameter (ONSD) measurement in predicting the development of PDPH in patients undergoing spinal anesthesia.

Methods: According to the American Society of Anesthesiology (ASA) physical classification I-III, 83 patients aged 18-65 years scheduled for spinal anesthesia for elective surgery were included in the study.

Endoscopic Evacuation of Subdural Collections.

Aim: Intraoperative use of the endoscope is a hot topic in neurosurgery and it gives broader visualization of critical and hardlyreached areas. Endoscope-assisted surgical approach to chronic subdural haematoma (SDH) is a minimally invasive technique and may give an expansion to the regular method of burr-hole haematoma drainage.

Material And Methods: Endoscope-assisted haematoma drainage with mini-craniotomy was performed over a 24-month period, and prospectively collected data is reviewed.

Surgical anatomy of the cavernous sinus, superior orbital fissure, and orbital apex via a lateral orbitotomy approach: a cadaveric anatomical study.

Background: Tumors of the middle fossa or cavernous sinus (CS), or intraorbital tumors, can penetrate each other through the superior orbital fissure (SOF) or neighboring tissue. These complicated pathologies are often treated with highly invasive surgical procedures. In this article, we demonstrate surgical anatomic dissections of the CS, SOF, orbital apex (OA), and dura mater extending to the periorbita from the middle fossa, by performing an epidural dissection via a lateral orbitotomy approach, and discuss findings that may provide guidance during surgery in these regions.

Comparison of Stabilization and Fusion Methods with Xenograft Plate Screws After Anterior Lumbar Corpectomy in Dogs.

Aim: Fusion development is the primary goal in spinal surgeries that are conducted for the treatment of vertebral body pathologies such as trauma, tumor and infection. Stabilization using metal plate screws together either with an autograft, allograft or xenograft is used. We evaluated fusion development in stabilizations that were carried out with xenograft (XG) with XG plate-screw (XPS) and XG with metal plate-screw (MPS) systems in dogs" lumbar vertebrae (L5-7 segment) in terms of radiological, biomechanical and histopathological aspects.

General versus epidural anesthesia for lumbar microdiscectomy.

This study was a retrospective analysis of 850 lumbar microdiscectomy (LMD) under epidural anesthesia (EA; n=573) or general anesthesia (GA; n=277) performed by the same surgeon and paid by invoice to the Social Security Institution of the Turkish Republic between April 2003 and May 2013. Although GA is the most frequently used method of anesthesia during LMD, the choice of regional anesthetia (epidural, spinal or a combination of these) differs between surgeons and anesthetists. Studies have reported that EA in surgery for lumbar disc herniation may be more reliable than GA, as it enables the surgeon to communicate with the patient during surgery, but few studies have compared the costs of these two anesthetic methods in LMD.

A Turkish study on menarche and menstrual experiences and their effects on attitudes towards menopause.

The purpose of this study was to investigate women's menarche and menstrual experiences and their effects on attitudes towards menopause. This research was planned as cross-sectional. A total of 300 women who had applied for a physical examination at the Maternity and Gynecology and Children's Hospital of Ordu province of Turkey were recruited for the study using the convenience sampling method.

Intraocular neuromuscular choristoma: a case report and literature review.

Background And Importance: Neuromuscular choristomas (NMCs) are rare benign tumors of the peripheral nerves. Although histopathological characteristics of this unusual lesion have been recognized, in this regard, neuroimaging findings have not been well described previously. We report the first intraconally located NMC affecting the oculomotor nerve, with histopathological and radiological characteristics.

Anatomical study of the cavernous sinus emphasizing operative approaches.

Aim: The aim of this article is to describe the microsurgical anatomy of the cavernous sinus, the triangles, and the osseous relationships in the region with special attention to the relationships important in surgical approaches on the intracavernous structures.

Material And Methods: Fifty cavernous sinuses obtained from twenty-five cadaver heads were studied in detail using magnification. Stepwise dissections of the cavernous sinuses performed to demonstrate the intradural and extradural routes, anatomy of the triangles and osseous relationships in the region.

Urodynamic findings in the tethered spinal cord: the effect of tethered cord division on lower urinary tract functions.

Purpose: The aim of this study is to evaluate the effect of division of the tethered spinal cord urodynamically in spinal dysraphic cases.

Methods: Between 1995-1997, 20 cases (11 males, 9 females) aged from 5 months to 13 years with TSC were investigated. 13 cases (65%) were classed as belonging to the myelomeningocele group and 5 cases (35%) to the spina bifida occulta group.

Complications of brain tissue pressure monitoring with a fiberoptic device.

Seventy-five patients with intracranial hypertension whose Glasgow Coma Score (GCS) was 8 or below and in whom intracranial pressure (ICP) was monitored were examined for complications of this procedure. In 20 of the 75 patients we used only an intraparenchymal fiberoptic ICP monitoring transducer, while, in the remaining 55 patients, who required CSF drainage, a ventricular drainage set (VDS) was used in addition to ICP monitoring. The duration of monitoring with the ICP transducer alone was approximately 5.
