Anatomy of the Petrosphenoidal Ligament and Its Relationship with the Abducens Nerve in Newborn Cadavers.

Aim: To examine the anatomy of the petrosphenoidal ligament (PSL), and its relationship with the abducens nerve (AN) in newborn cadavers.

Material And Methods: Using 10 formalin-fixed newborn cadavers, 20 PSLs and ANs on both sides were examined. The structure of each PSL, its morphometric features, and its relationship with the AN were evaluated.

An atypical anatomical variation of the petrosphenoidal ligament in a newborn cadaver.

Purpose: To report an atypical anatomical variation of the petrosphenoidal ligament in a newborn cadaver and to discuss its clinical significance.

Methods: During a study of ten newborn cadavers, the skull base was dissected to reveal the anatomy of the petrosphenoidal ligament and its relationship with the abducens nerve. An atypical anatomical variation was observed, and this is described.

Nitric oxide synthase inhibitors protect cerebellar Purkinje cells from zinc-induced cell loss in adult rat.

Zinc is an important trace element in biological systems; however, excessive extracellular zinc could lead to neuronal cell death following ischemia, seizures, and brain trauma. In this study, we investigated whether the intracortical injection of zinc sulphate (200 μg/kg, i.c.

Volumetric evaluation of the paranasal sinuses in normal subjects using computer tomography images: a stereological study.

Objective: The size and shape of paranasal sinuses are especially relevant when considering endoscopic sinus surgery. For this reason, the size of the paranasal sinuses has been the subject of many studies, none of which has used stereological methods to estimate the volume. In the present stereological study, we estimated the volume of paranasal sinuses of normal males and females.

The average values of the nasal anthropometric measurements in 108 young Turkish males.

Objective: The aim of the study was to describe the average values of the nasal anthropometric measurements in young Turkish male population.

Methods: Study group consisted of 108 volunteer young Turkish males whose age were 18-30 years (mean age 22.31 year).

The effects of section thickness on the estimation of liver volume by the Cavalieri principle using computed tomography images.

Estimation of liver volume using routine CT scans has been described previously. We have, however, not found a gold standard study which analyzes the effect of section thickness on the estimation of liver volume using CT images. In the present study, five normal livers obtained from cadavers were scanned using a Spiral CT Scanner (Xpress/GX Toshiba, Tocigi-Ken) in the horizontal plane.

Unbiased estimation of the liver volume by the Cavalieri principle using magnetic resonance images.

Objective: It is often useful to know the exact volume of the liver, such as in monitoring the effects of a disease, treatment, dieting regime, training program or surgical application. Some non-invasive methodologies have been previously described which estimate the volume of the liver. However, these preliminary techniques need special software or skilled performers and they are not ideal for daily use in clinical practice.

A deep femoral artery passing in front of the femoral vein.

It is known that a different ramification pattern can occur as a function of the development of the arteries of the lower limb. During a routine dissection, a variation of the deep femoral artery was found passing in front of the femoral vein in the left lower limb of a 43-year-old male cadaver. This case is reported because of its rare occurrence in the literature.
