The results of a clinico-anatomic study of the auricular branch of the vagus nerve (ABVN) and Arnold's ear-cough reflex are presented. The frequency of the ear-cough reflex was found to be 2.3% (12 out of 514 patients). It was bilateral in 3 cases (0.6%). The reflex was elicited by palpation of the postero-inferior wall of the external acoustic meatus (EAM)(More)
OBJECT The vascularization pattern of the anatomy of the distal anterior cerebral artery (ACA) remains a subject of debate. The authors provide detailed information about the distal ACA and shed light on issues concerning it that have not previously been adequately discussed. METHODS Fifty adult human brains (100 hemispheres) were obtained during routine(More)
BACKGROUND Advances in microsurgical techniques made possible the removal of advanced jugular foramen (JF) lesions, which once had been accepted as unoperable. However, successful surgery requires detailed knowledge of the JF anatomy. METHODS Sixteen jugular foramina in eight formalin-preserved adult cadavers were scanned with axial and coronal high(More)
We aim to evaluate the mechanisms responsible for complications during trigeminal rhizotomy via foramen ovale puncture. Ten dry skulls and 10 skull-base specimens were investigated in the present study. In cadaveric skull-base specimens, the anatomical relationships between the foramen ovale, mandibular nerve and Gasserian ganglion and the surrounding(More)
OBJECTIVE Although several clinical applications of transpedicular screw fixation in the cervical spine have been documented recently, few anatomic studies concerning the cervical pedicle are available. This study was designed to evaluate the anatomy and adjacent neural relationships of the middle and lower cervical pedicle (C3-C7). The main objective is to(More)
BACKGROUND The precentral gyrus (PG) is the primary motor area and is one of the most eloquent brain regions of neurosurgical interest. Although the arterial supply to the PG is generally known, contributions from different arterial branches such as the anterior cerebral artery (ACA), posterior cerebral artery (PCA), and middle cerebral artery (MCA) have(More)
Posterior transpedicular screw fixation has been widely used for the management of unstable lumbosacral spine caused by trauma, degenerative conditions, congenital defects and neoplasms. Knowledge of the pedicle diameters of the first sacral vertebra is crucial for safe placement of the screws. Thirty dry sacral specimens (18 male, 12 female) were used for(More)
STUDY DESIGN Measurements of the length of pediculocorporeal screw trajectory were performed on bony sacra. Outer interforaminal distances of the first sacral vertebra were measured on bony sacra and anteroposterior sacral radiographs. OBJECTIVES To demonstrate the correlation of the length of pediculocorporeal screw trajectory of the first sacral(More)
BACKGROUND PRF treatment has recently been described as minimally neurodestructive alternative to radiofrequency heat lesions. Patients with some pain syndromes in whom the pain could not be controlled by alternative techniques may be treated using PRF. In the present study, our main goal was to evaluate and compare the ultrastructure of peripheral nerve(More)
BACKGROUND The pterion, the most commonly used neurosurgical landmark, is defined as the junction of frontal, parietal, and greater wing of the sphenoid and the squamous part of temporal bones. Our aim was to identify the variations of the pterion which may be a potential surgical pitfall. METHODS Both sides of 300 adult skulls were examined but 110 sides(More)
