Minimally invasive radiofrequency treatment for facial muscle spasm Facial muscle spasm, also known as facial muscle twitching. It is a condition of involuntary twitching of the half side of the face. The twitching is paroxysmal and irregular, with varying degrees, and can be aggravated by fatigue, mental stress and voluntary movements. At present, symptomatic treatment is generally used, but the effect is not satisfactory. The pain department of our hospital adopts radiofrequency technology for minimally invasive treatment of facial muscle spasm, and the efficacy is remarkable. The treatment of facial muscle spasm by radiofrequency minimally invasive is simple and easy, and can be done on an outpatient basis, using a special radiofrequency cannula needle stabbed in the direction of the stem mammary foramen, finding and locating the facial nerve trunk under nerve stimulation, and causing a certain degree of thermal denaturation of the nerve through temperature-selective radiofrequency thermal coagulation, under the monitoring of facial nerve function, in order to reduce the nerve fibers conducting abnormal impulses. In the past two years, we have relieved the pain of dozens of patients with persistent facial muscle spasm for many years, which is highly praised by the patients who have recovered.
