3. Clinical manifestations of sequela of facial paralysis:
Secondary hemifacial spasm, facial muscle joint movement (mouth-eye linkage), crocodile tears syndrome (crocodile tears sign), facial atrophy, facial tension, dull complexion, rabbit eye sign, dry eyes, dry nose, dry mouth, auditory allergy, mouth opening, jaw joint ringing, croaking noise when eating on the primary side of the skull, diplopia of eyes, tight neck and scalp, alopecia, smaller eyes on the affected side, etc. Facial scalp and neck are afraid of cold, facial muscles are stiff, tears are shed in the wind, the color of "Lee's Wind Mass" becomes darker, and facial sensation is abnormal (all soreness and numbness are called pain and discomfort).
1), secondary hemifacial spasm:
The main manifestations are paroxysmal involuntary spasms or convulsions that occur in certain facial expression muscles, such as eyes, mouth corners and platysma. , mostly unilateral, both sides participate.
2), facial muscle joint movement (mouth-eye linkage):
When blinking, the upper lip of the affected side moves upward, and when speaking, the lower eyelid of the affected side moves downward.
3), crocodile tears syndrome (crocodile tears):
Patients with sequela of facial paralysis shed tears when chewing food. At this time, there will be sequelae of facial paralysis in large and small eyes. You can search online for pictures of large and small eyes of facial paralysis sequelae. The sequela of facial paralysis is uncomfortable eyes. This is because the mouth-eye interaction of facial paralysis sequelae corresponds to gland atrophy.
4), facial muscle atrophy:
Facial muscle atrophy refers to the reduction of the volume, weight and function of parenchymal cells, tissues or organs that have developed normally. Protein synthesis of atrophic cells decreased, but decomposition increased, so as to adapt to their living environment with low nutritional level. Facial muscle atrophy belongs to denervated atrophy (facial nerve can regulate facial muscle metabolism). When the nerve trunk is damaged, the corresponding tissue will shrink due to the loss of neuromodulation. ) and disuse atrophy (facial muscles can't move for a long time, and nerve receptors lack centripetal stimulation, so centrifugal impulses are reduced, leading to gradual reduction of blood supply and substance metabolism and atrophy).
5), facial tightness:
Facial muscles atrophy, solid cells become smaller due to malnutrition, cell gaps become narrower, and they lose their due elasticity.
6) The face is black;
After facial muscle atrophy, the function is low, the blood flow becomes smaller, the facial muscle loses its luster and becomes dull and withered.
7), rabbit eye sign:
When the sequela of facial paralysis is particularly serious, the upper and lower eyelids atrophy and eversion, and the eyeballs are red, which looks like rabbit eyes, also called "rabbit eye sign". At this time, the eye fission is large.
8) Dry eyes, dry nose and dry mouth:
The sequela of facial paralysis is caused by gland atrophy.
9), auditory allergy:
The mechanism of auditory hypersensitivity (hyperacusia) is that tensor tympani, which keeps the tympanic membrane tense, is innervated by medial pterygoid nerve, a branch of trigeminal nerve, and stapedius muscle is innervated by facial nerve. These two muscles are antagonistic and keep balance. When facial paralysis occurs, the stapedius muscle is paralyzed. Therefore, the tensor tympani is relatively tense, and the tension of the tympanic membrane is high, and the small voice produces strong vibration, resulting in hyperhearing, which is seen in facial nerve lesions above the stapedius muscle branch. Some people will also have facial paralysis with tinnitus and even deafness. It varies from person to person.
10), the mandibular joint ring, when talking or eating, the primary side skull makes a "cough, cough, cough" sound:
It is caused by atrophy of mandibular joint muscles.
1 1), eyes diplopia:
Atrophy of eyeball on the affected side of sequela of facial paralysis is a phenomenon that one object is regarded as two objects, because the muscles on one side of the face are severely atrophied and the eyes cannot converge equally, so that the image of the watched object cannot be imaged on the symmetrical point of the retina of both eyes. This visual impairment has brought extreme discomfort to patients. Although one eye has normal vision, two eyes have blurred vision, nausea and vomiting, headache, dizziness and unsteady gait. They like to close one eye involuntarily, or take compensatory head position to eliminate or alleviate symptoms, and then cause torticollis or general discomfort. Severe symptoms may be misdiagnosed as brain tumors, increased intracranial pressure, etc., and unnecessary expensive examinations are done in neurology.
12), tight neck and tight scalp:
Neck and scalp muscles atrophy, solid cells become smaller due to malnutrition, cell gaps become narrower, and they lose their due elasticity.
13), alopecia:
After the scalp muscle atrophy, the function is low, the blood circulation is reduced, and the hair follicle can not get enough nutrition.
14), the eyes and face of the affected side of the external auditory canal become smaller, the nose inclines to the affected side, and the upper and lower teeth cannot be centered;
Muscle atrophy of the affected side, coupled with incomplete recovery of paralysis, inconsistent muscle tension on both sides.
15), both eyebrows cannot be raised to the same height;
The affected forehead muscles are still partially paralyzed.
16), face, scalp and neck are afraid of cold;
Face, scalp and neck are afraid of cold because wind evil in these parts brings less heat energy through blood.
17), facial muscle stiffness:
Facial muscle stiffness is caused by facial muscles full of pathogenic wind, qi stagnation and blood stasis, and phlegm coagulation and toxin accumulation.
18), crying in the wind:
Tears in the wind are caused by partial paralysis of eyelids, inflexible eyelid movement and limited blink reflex, which can not protect the eyeball normally, resulting in excessive stimulation of eyes by wind, sand, sunlight and bacteria.
19), the color of "Lee's Wind Mass" darkens:
The color of "Lee's Wind Mass" darkens, the spider's legs become thinner, shorter and flatter, and the color gradually deepens. There are purple and black patches scattered like stars in the sky below the wind.
20) Abnormal facial sensation (all soreness and numbness are called pain and discomfort):
All sensory abnormalities, discomfort, especially tenderness, are signs of incomplete cure. Traditional Chinese medicine says, "General principles do not hurt, general principles do not hurt". According to the "Lee's standard" after facial paralysis treatment, it can be cured: "The eyes are the same size, the mouth is not crooked when laughing, the eyebrows are raised as high, the mouth is not thirsty, the eyes are not afraid of the wind, and the cold face is not tight in cold weather." And whether the "Li Feng Tuan" has completely disappeared.
