Most patients with primary facial muscle spasm develop after middle age, with more women. The twitching of the orbicularis oculi muscle is most easily noticed in the early stage of the disease, which gradually and slowly extends to the other facial muscles on one side of the face.
Twitching of the orofacial muscles is manifested as involuntary twitching of one side of the face. The twitching is paroxysmal and irregular, with varying degrees, and can be aggravated by fatigue, mental tension and voluntary movement. So what are the examinations needed for the twitching of the orofacial muscles?
1, electromyography examination The functional state of peripheral nerves, neurons, neuromuscular junction and muscles themselves can be determined by electromyography examination. EMG can not only diagnose the degree of nerve damage and estimate the prognosis, but also identify whether the muscle atrophy is neurogenic or myogenic, or disuse atrophy.
2, cerebrospinal fluid lysozyme cerebrospinal fluid lysozyme test can reflect a more sensitive indicator of the functional status of phagocytes. Elevated: septic meningitis, brain tumor or blood-brain barrier disruption Significantly elevated: tuberculous meningitis Increased significantly Reduced: viral encephalitis 3. The level of CaM in CSF is increased in patients with cerebral infarction, and the magnitude of the increase is related to the infarct area. The person who needs to be tested is a person with heavy cranial injury.
4.Cerebrospinal fluid glutamine Cerebrospinal fluid glutamine test is significant for people with impaired liver function, respiratory distress, chest pain, vomiting and convulsions.
5, cerebrospinal fluid calcium Cerebrospinal fluid calcium test is important for people with stiff neck, severe headache, loss of appetite, confusion, vomiting, convulsions, lethargy, sleepiness, sensitivity to light, small blood spots on the skin, skin rash and other symptoms.
6.Cerebrospinal fluid potassium The cerebrospinal fluid potassium test is important for people with high fever (>40℃), stiff neck, severe headache, loss of appetite, unconsciousness, vomiting, convulsions, lethargy, sleepiness, sensitivity to light, small blood spots on the skin, skin rash and other symptoms.
7.Blood routine Blood test is used to determine the disease by observing the change in quantity and morphological distribution. It is one of the common auxiliary examinations for doctors to diagnose the disease.
