The hypoglossal nerve can be damaged at the hypoglossal nucleus (nuclear), above the hypoglossal nucleus (supranuclear), or interrupted at the motor axons (infranuclear).
Amyotrophic lateral sclerosis (ALS) 2. These areas are all connected to the ninth cranial nerve, also called the glossopharyngeal nerve. Usually, one side of the tongue is affected, and when the person sticks out his or her tongue, it deviates or points toward the side that is damaged. The hypoglossal nerve can be damaged at the hypoglossal nucleus (nuclear), above the hypoglossal nucleus (supranuclear), or interrupted at the motor axons (infranuclear). The hypoglossal nerve is usually tested by asking the patient to stick out their tongue, and move it from side to side. We reviewed the pathophysiological causes of hypoglossal nerve injury and discuss the associated clinical and procedural characteristics of affected patients. Multiple sclerosis 3. The following mechanisms of injury have been proposed in published cases: pressure to the lateral roots of the tongue during routine intubation using the McIntosh blade with hyperextension of the head, 5and a difficult intubation in which cricoid pressure or forceful laryngoscopy are used, 10which can result in hypoglossal nerve injury. Multiple cranial neuropathies are commonly caused by tumors, trauma, ischemia, or infections.While diagnosis can usually be made based on clinical features, further investigation is often warranted to determine the Hypoglossal nerve damage from surgical causes is uncommon, occurring in only 0.42% of functional neck dissections.

In much rarer instances it The twelve cranial nerves, the hypoglossal nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column There were rightsided cerebellar signs Thereafter, the trigeminal and oculomotor nerve roots were harvested for further processing Quais so os nervos cranianos? If the symptoms are accompanied by acute pain, a possible cause may be dissection of the internal carotid artery. The most common causes of bulbar palsy include brainstem strokes and tumors. The most proximal portion of the small intestine is the duodenum.Its name is derived from the Latin duodenum digitorum, meaning twelve fingers length.It runs from the pylorus of the stomach to the duodenojejunal junction..
Mobilization of the hypoglossal nerve is commonly necessary, especially when a high carotid bifurcation is present. We report two cases of male patients who developed persistent idiopathic isolated unilateral hypoglossal nerve palsy. Such damage causes paralysis, fasciculations (as noted by a scalloped appearance of the tongue), and eventual atrophy of the tongue muscles. In this light, a proximal injury to the hypoglossal nerve may also involve the IX, X, XI complex and cause a complex neuropathy with oropharyngeal signs and symptoms and hoarseness as well as tongue weakness. The patient's symptoms began to abate 5 days later. The traction was reduced, and a corticosteroid was administered.
