How do you test for hypoglossal nerve damage?

The hypoglossal nerve can be examined by asking a patient to protrude their tongue, move their tongue laterally, and place their tongue against their cheek to resist the opposing force of the examiner’s hand resting on the external cheek.

What causes hypoglossal nerve palsy?

1 Numerous causes of isolated hypoglossal nerve palsy have been described. Intracranial neoplasms, skull base neoplasms, and vertebral trauma have classically been reported as the most frequent causes, accounting for up to 50% of cases.

What happens if hypoglossal nerve 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). Such damage causes paralysis, fasciculations (as noted by a scalloped appearance of the tongue), and eventual atrophy of the tongue muscles.

How do you test CN XII?

Cranial Nerve 12 – Motor The 12th CN is tested by having the patient stick out their tongue and move it side to side. Further strength testing can be done by having the patient push the tongue against a tongue blade. Inspect the tongue for atrophy and fasciculations.

What is hypoglossal palsy?

Hypoglossal Nerve in Neurologic Disorders: Progressive bulbar palsy and advanced MND can cause severe tongue atrophy and an inability for the tongue to be protruded leading to the inertia of the tongue. Fasciculations frequently occur with atrophy in the case of motor neuron disease.

Is tongue paralysis curable?

There isn’t a cure for permanent paralysis. The spinal cord can’t heal itself. Temporary paralysis like Bell’s palsy often goes away over time without treatment. Physical, occupational and speech therapy can accommodate paralysis and provide exercises, adaptive and assistive devices to improve function.

What causes 12th cranial nerve palsy?

Disorders of the 12th cranial nerve (hypoglossal nerve) cause weakness or wasting (atrophy) of the tongue on the affected side. This nerve moves the tongue. Hypoglossal nerve disorders may be caused by tumors, strokes, infections, injuries, or amyotrophic lateral sclerosis.

Can hypoglossal nerve damage be repaired?

Repair of Hypoglossal Nerve Injury Similar to facial nerve repairs, the ideal management involves establishment of a tension-free anastomosis (Avitia & Osborne, 2008). Although this is preferably performed with end-to-end anastomosis if possible, the use of interposition grafts can be used.

Can tongue paralysis be cured?

The condition is irreversible. Paralysis can affect any part of the body. It can be: Partial (paresis): You can control some muscles, but not all.

What is the normal function of the hypoglossal nerve XII?

The hypoglossal nerve enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles. These muscles help you speak, swallow and move substances around in your mouth.

Can the hypoglossal nerve be repaired?

How do you cure a paralyzed tongue?
