Facial muscle spasms, also known as facial twitches, manifest as involuntary twitching on one side of the face. The twitches manifest in varying degrees of paroxysmal and irregularity and may be exacerbated by fatigue, mental stress and anger. The onset of the disease usually begins in the orbicularis oculi muscle and then involves the ipsilateral half of the face. The disease mostly occurs after middle age and can occur in both men and women. Most primary facial spasms occur after middle age. At the beginning of the course of the disease, most of them are paroxysmal involuntary twitches of the orbicularis oculi muscle on one side, which gradually spread to the other muscles of one side of the face. In severe cases, it also includes the ipsilateral vastus cervicis muscle, but less frequently involves the frontalis muscle. The degree of spasticity varies from paroxysmal to rapid and irregular. The initial spasm is relatively mild and lasts only a few seconds. Thereafter, the spasm may gradually increase to several minutes or longer, while the intervals become progressively shorter and the spasm progressively more intense. In severe cases, the muscles stiffen, resulting in inability to open the ipsilateral eye and tilting the corner of the mouth to the ipsilateral side. Twitching symptoms are often exacerbated by fatigue, stress and anger. The convulsions last from a few seconds to ten minutes with indeterminate intervals. Patients feel distracted and unable to work or study, which seriously affects their physical and mental health. Most tics stop after sleep. Bilateral lateral muscle spasms are rare, and if they occur, the patient may be suffering from a different condition called blepharospasm. The pathogenesis and treatment of eyelid spasms is completely different from that of facial spasms. In a small number of cases, the twitching is accompanied by ipsilateral tinnitus and hearing loss. If you find any of these symptoms in your life, please go to a regular hospital as soon as possible and register with a neurosurgeon, so that the specialist can improve the examination and develop a treatment plan based on the patient’s specific symptoms and signs.
