What symptom does hypoglossal nerve damage have?

summary

Hypoglossal nerve is the last pair of twelve pairs of cranial nerves, and its injury is very common in clinic. It is often combined with medullary lesions and clinical manifestations of posterior cranial nerves, and sometimes appears as a single injury. The single injury of hypoglossal nerve may occur in the retromandibular space, submandibular region, oral cavity or mandibular horizontal branch. Nerve paralysis caused by contusion, bleeding and infiltration of local anesthesia around the nerve is usually temporary, or only slight remains are left. Nerve contusion or rupture showed paralysis of lingual muscle on the affected side. The tip of tongue tilted to the affected side when extending the tongue, and then atrophied. Now let's talk about the symptoms of hypoglossal nerve injury.

What symptom does hypoglossal nerve damage have?

The first is simple peripheral hypoglossal nerve injury, unilateral hypoglossal nerve paralysis, lingual muscle paralysis on the affected side, tongue tip leaning to the affected side, lingual muscle atrophy on the affected side; Both sides of hypoglossal nerve paralysis is complete paralysis of the tongue muscle, tongue at the bottom of the mouth can not be extended, and speech, dysphagia.

Second: hypoglossal nerve injury (bulbar palsy) with posterior group brain nerve injury. Posterior group brain nerves (glossopharyngeal nerve, vagus nerve, accessory nerve, hypoglossal nerve) all originate from the medulla oblongata, and they are closely related to each other. Middle pivot hypoglossal nerve injury (nuclear and supranuclear) and peripheral hypoglossal nerve injury of skull base combined with posterior group brain nerve injury are often combined in the clinical manifestations of medulla oblongata related lesions, and appear in the form of medulla oblongata paralysis, which is one of the most common and important types of hypoglossal nerve injury.

Third: unilateral or bilateral tongue movement disorder, followed by atrophy of the tongue muscle and muscle fibrillation; The lips are often weak and can not inflate, that is, the use of fingers to close the nostrils often still can not inflate the gills, can only inflate the gills when pressing the lips. The palatal arch paralysis and sucking reflex disappeared. Tongue atrophy with or without tongue muscle fibrillation and abnormal brainstem reflex.
