Internal carotid arterial dissection is a relatively rare condition that can cause neck pain and/or ischemic symptoms. Cranial nerve palsy caused by internal extremely rare. A 39-year-old male massaged his with fingers. He experienced transient pain. After one week, he demonstrated hypoglossal palsy. The radiological studies revealed extracranial dissection. Cervical self-massage may and For th...

chwannomas are tumon arising Ilom the myelin-producing Schwann cells of the peripheral sensory nervous system. Of those occuning in the head and neck region, most are infracranial. lnvolvement of cranial nerves containing motor fibers alone is uncharacteristic. Schwannomas of the l2th cranial nerve are rare, with most originating intracranially, although some may extend extracranially with prol...

Vascular compression is a known cause of cranial nerve dysfunction in a variety of disease states including trigeminal neuralgia, hemifacial spasm, and hypoglossal neuralgia.(1,2.)

Purpose. Hypoglossal nerve palsy after use of the laryngeal mask airway (LMA) is an exceptionally rare complication. We present the first case of unilateral hypoglossal nerve palsy after use of the LMA Supreme. Clinical Features. A healthy 67-year-old female was scheduled for a hallux valgus correction under general anesthesia combined with femoral and sciatic nerve blocks. A size 4 LMA Supreme...

In this study we aimed to examine a role for interleukin 6 (IL-6) and its receptor (IL-6R) in peripheral nerve regeneration in vivo. We first observed that cultured mouse embryonic dorsal root ganglia exhibited dramatic neurite extension by simultaneous addition of IL-6 and soluble IL-6R (sIL-6R), a complex that is known to interact with and activate a signal transducing receptor component, gp1...

If normal, eupneic breathing fails, gasping is recruited. Serotonin was proposed as essential for gasping, based on findings using an in vitro mouse preparation. This preparation generates rhythmic activities of the hypoglossal nerve that are considered to be akin to both eupnea and gasping. In previous studies, gasping of in situ rat and mouse preparations continued unabated following blockers...

We have examined the time course of the neuronal death and regeneration of rat axotomized hypoglossal nerve with various conditions of the nerve resection, and established a useful system to measure neurotrophic activities of bioactive substances. In this system, neuronal death can be evaluated by counting surviving neurons in the nucleus of hypoglossal neuron at the brain stem, and the degree ...

This article describes a case of prominent emissary veins of the hypoglossal canal protruding into the cerebellomedullary cistern mimicking disease, such as a nerve sheath tumor. The diagnosis and differentiation in this instance were confirmed by MR angiography and a review of alternative imaging planes. A diagnosis of hypoglossal canal lesions should be made with caution, as these lesions are...

Following an upper respiratory tract infection, a teenage girl developed an isolated right XII nerve palsy; subsequently she was shown to have infectious mononucleosis. After 24 weeks her tongue had virtually recovered.
