Facial muscle spasm and blepharospasm in the face onset but two conditions, are prone to misconceptions. Then the next for you to introduce the introduction. Blepharospasm occurs in middle-aged and elderly women, often bilateral lesions, progressive progression, 2/3 for women, most of the stabilization in 3-5 years, manifested as frequent and involuntary transient eyes, eyes tightly wrinkled, both eyes spasmodic or tonic eyelid closure, at the same time due to the orbicularis oculi muscle long-term severe spasm will cause eyebrow ptosis, ptosis and eyelid skin relaxation, and other secondary lesions. These patients often have good vision, but are unable to use it well because the eyes always close involuntarily. And these patients often can’t open their eyes the more they try to use them, while they can open them well when they are mentally relaxed without using them. Facial muscle spasm, also known as hemifacial spasm, is an involuntary spasm of the facial muscles, some patients are due to one side of the blepharospasm gradually extended to the same side of the corners of the mouth and the whole half of the face, the patient talking, eating, and other facial movements can be triggered or aggravated by the spasm, and can not be consciously control the spasm, the more nervous the more prone to seizures, and therefore very painful. There are many patients who can’t distinguish between blepharospasm and facial muscle spasm, just like the patient above. There is a fundamental difference between the two, the most direct difference is that the former is manifested in the bilateral eye, the latter is mostly manifested in the unilateral eye and face, there are also bilateral but very rare. Through the introduction of the above we have learned the characteristics of these two symptoms, so we recommend that patients and friends early treatment and early recovery.
