The Hypoglossal Nerve in Carotid A rterial Reconstructions • The importance of hypoglossal nerve in performing carotid arterial reconstructions has been illustrated by two case reports. Unilateral palsy is troublesome but bilateral damage may result in upper airway obstruction. Simple surgical maneuvers consisting of division of the sternocleidomastoid artery and vein and freeing up of the desc...

The activity of the hypoglossal nerve was recorded during pharyngeal loading in sleeping dogs with chronically implanted cuff electrodes. Three self-coiling spiral-cuff electrodes were implanted in two beagles for durations of 17, 7, and 6 mo. During quiet wakefulness and sleep, phasic hypoglossal activity was either very small or not observable above the baseline noise. Applying a perpendicula...

We report a case of isolated hypoglossal nerve paralysis caused by a dural arteriovenous fistula. Diagnosis is discussed with emphasis on conventional and MR angiography. The anatomy of the hypoglossal nerve is reviewed along with more common causes of pathologic conditions.

PURPOSE To illustrate and describe the appearance of both long-standing and relatively recently occurring motor denervation of the hypoglossal nerve and of the third (mandibular) division of the trigeminal nerve (V3), with emphasis on findings particular to MR imaging. METHODS Findings from 11 patients with V3 denervation and from seven patients with hypoglossal denervation resulting from a v...

Isolated unilateral hypoglossal nerve palsy (IUHNP) is rare because of its complex course and close adjacent structures. Prostate cancer a very cause reported scarcely. We herein report the first case metastatic prostate presented with IUHNP in Korea, which shows good clinico-radiological correlation.

A case of an isolated hypoglossal nerve palsy is reported. The differential diagnosis is discussed, in the context of the requirement for careful scrutiny of the entire course of the hypoglossal nerve on imaging, to detect underlying pathology remote from the tongue, and to avoid unnecessary invasive diagnostic procedures prompted by the appearance of a 'pseudomass' of the weak tongue both clin...

OBJECTIVE Hypoglossal-facial neurorrhaphy has been widely used for reanimation of paralyzed facial muscles after irreversible proximal injury of the facial nerve. However, complete section of the hypoglossal nerve occasionally results in hemiglossal dysfunction and interferes with swallowing and speech. To reduce this morbidity, a modified technique with partial section of the hypoglossal nerve...

AbsractA rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. The superior root of the Ansa cervicalis was formed by the C1 ventralramus. It accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. Moreover the C1 ventral ramus formed fromthe sheath and joined the inferior root from C2 and C3 ventr...

OBJECTIVES To report a case of paraganglioma arising from the hypoglossal nerve and review the anatomy, clinical features, and literature to date. STUDY DESIGN Case report and review of the literature. METHODS Case records including paper and electronic chart and imaging reports were reviewed and summarized for the index case. A literature search was performed using pubmed keywords paragang...
