Otolaryngologists are frequently confronted with the management of cervical tumors. Neurogenic tumors concern, especially, the cranial, sympathetic, or peripheral nerve sheathes. These tumors are benign and grow slowly. The involvement of the cervical part of the phrenic nerve is exceptional, and only 2 cases are reported in the literature. We describe the first case of a cervical schwannoma in...

Silver, I., B. Li, J. Szalai, and M. Johnston. Relationship between intracranial pressure and cervical lymphatic pressure and flow rates in sheep. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R1712–R1717, 1999.— Previous reports from our group demonstrated that about one-half of the total volume of cerebrospinal fluid (CSF) removed from the cranial vault in sheep is transport...

This study was aimed, by means of the retrograde tracing technique, at disclosing the distribution of efferent neurones innervating the porcine oviduct. The fluorescent retrograde tracer Fast Blue was injected into the wall of the right oviduct in six juvenile pigs during laparotomy performed under anaesthesia. After a recovery period of 3 weeks the animals were reanaesthetised, perfused with 4...

The distribution of choline acetyltransferase (ChoAcTase)-like immunoreactivity in the superior cervical ganglion and the stellate ganglion was analyzed with immunohistochemistry. A dense network of ChoAcTase-immunoreactive nerve fibers was observed in both ganglia studied. The ChoAcTase-positive fibers were found in all parts of the ganglia but had a differential distribution, giving rise to a...

BACKGROUND Pulsed radiofrequency treatment has recently been described as a non-neurodestructive or minimally neurodestructive alternative to radiofrequency heat lesions. In clinical practice long-lasting results of pulsed radiofrequency treatment adjacent to the cervical dorsal root ganglion for the management of chronic radicular spinal pain have been reported without neurologic complications...

OBJECTIVE To describe the location of the dorsal root ganglion in relation to the intervertebral disc, including the "triangular" safety zone for minimally invasive surgery in the lumbar spine. METHODS Eight adult cadavers were dissected bilaterally in the lumbar region, using a posterolateral approach, so as to expose the L3L4 and L4L5 spaces, thereby obtaining measurements relating to the s...

489 Abstract: The presence and distribution of Griffonia Simplicifolia I-B4 (GSA I-B4) and Calcitonin Gene Related Peptide (CGRP) were studied in the nodose ganglion (NG) (inferior ganglion of the vagus nerve), sphenopalatine ganglion (SPG) and superior cervical ganglion (SCG) of the rat. GSA I-B4 labeling was found in all ganglia tested. Neither SPG nor SCG cell bodies stained with CGRP were u...

The associations between dimensions of the first cervical vertebra, atlas, and a representative set of craniofacial and postural variables were studied on cephalometric radiographs of a sample of 103 adult males aged 22-30 years, recorded in the natural head position (mirror position). Atlas morphology was expressed by nine variables, linear and angular craniofacial dimensions by 27 variables, ...

Ramsay Hunt syndrome is characterized by varicella zoster virus infection affecting the geniculate ganglion of the facial nerve. It typically presents with vesicles in the external auditory canal associated with auricular pain and peripheral facial nerve paralysis. Although vestibulocochlear nerve is frequently co-involved during the course of Ramsay Hunt syndrome, multiple lower cranial nerve ...
