What are the symptoms of facial nerve injury?

Facial nerve injury, also known as facial nerve palsy, is divided into central facial nerve palsy and peripheral facial nerve palsy. Peripheral facial nerve palsy is a disease characterized by facial expression muscle movement disorder, which is a common and frequent disease, not limited by age, and is mostly manifested as paralysis of facial expression muscles on the affected side, the disappearance of forehead wrinkles, the enlargement of eye fissures, the flat nasolabial folds, the downward slope of the corners of the mouth, and the drooping of the corners of the mouth and the crooked face when smiling or showing teeth. The affected side cannot wrinkle the forehead, frown, close the eyes, puff up and pout, etc., the cheeks and whistle are leaked because the lips on the affected side cannot be closed, and the food residue is often retained in the tooth and cheek space of the affected side when eating, and saliva often flows down from the side, and the tear spots turn outward with the lower eyelid, so that the tears cannot overflow according to the normal drainage.

If there is a head trauma or nerve damage in the process of surgery, it is easy to cause facial nerve damage, facial nerve damage will make the patient have a change in appearance, and even cause facial paralysis, facial nerve injury should be diagnosed as soon as possible**, in addition to the more obvious symptoms just mentioned, what are the three symptoms of facial nerve injury?

1. After facial nerve injury, the most typical symptom of the patient is the severe loss of motor function of several expression muscles such as the forehead, eyes, nose, lips, etc., so the patient has no way to accurately achieve certain expressions and even have strange expression symptoms on the appearance. The coordination of several expression muscles may also be too disordered, so the face will also jump unconsciously. Some patients also have different heights on both sides of the eyebrows, local paralysis of facial muscles, and inability to frown and stare at the eyes.

2. After facial nerve damage, the patient's face will be too swollen, and even cause bleeding from the fundus. It is suggested that hyperbaric oxygen can be used to improve the hypoxic state of nerve fibers, and at the same time, hyperbaric oxygen can also relieve edema, enhance the phagocytic ability of cells, and gradually improve the nerve control function of the face.

3. If the patient has facial nerve injury, the chewing ability will also be affected, because the muscles of the face and the muscular ability of the jaw are almost completely lost after the injury, so they cannot chew when eating. There may also be drooling, leakage of air and slurred pronunciation at the corners of the mouth.

In case of facial nerve injury, it is recommended to take conservative**, such as taking hormone drugs to reduce edema and help nerve recovery, or you can also use nerve nutrition drugs such as vitamin B1 and B12 to assist**. If conservatively** does not work, surgery** such as facial nerve decompression, or facial nerve anastomosis or grafting** is required. After the system, facial nerve damage can generally receive good results.

Nerve damage is divided into central nervous system damage and peripheral nerve damage, and the manifestations are different, as follows:

1. Central nervous system damage:

1. The patient's brain consciousness is dysfunctional, consciousness decreases, and symptoms of drowsiness, lethargy, coma, and delirium appear;

2. Cognitive function decline, manifested as memory and calculation decline, speech function, visuospatial disorders, etc.;

3. The patient is paralyzed on one side of the limb and has sensory impairment, and some patients present with aphasia, transient impairment of consciousness or transient general amnesia;

4. Seizures, the patient has symptoms such as convulsions of the limbs, dizziness, nausea, vomiting, difficulty swallowing, and choking on drinking water;

5. Spinal cord lesions, manifested as paralysis of one limb and numbness of the hemisphere, and patients will also present with crossover symptoms, manifested as numbness on one side and weakness of one limb or deep sensory impairment;

6. Symptoms of paraplegia, autonomic nerve disorder below the level of nerve damage, manifested as incontinence.

2. Peripheral nerve damage: manifested as numbness, pain, weakness, and atrophy.

Nerve damage depends on what kind of nerve damage it is. There are many types of nerves, and the symptoms of different nerve injuries are different. If the nerves that control the muscles of the limbs are damaged, the muscles will be paralyzed, leading to immobility and muscle atrophy.

If the sensory nerve is damaged, it can lead to loss and loss of sensation in the innervated area, resulting in loss of touch and pain and temperature. If it is cranial nerve injury, it will lead to nerve dysfunction of cranial nerves, such as olfactory nerve damage leading to loss of smell, optic nerve damage can lead to vision loss, vision loss and even blindness, and oculomotor nerve damage will affect the activity of the eyeball, resulting in double vision when seeing, auditory nerve damage, hearing loss, tinnitus and other symptoms.
