CT-guided facial nerve radiofrequency treatment for intractable area spasm The figure shows a female patient with intractable area spasm, with a history of more than 4 months, who was ineffective in conservative treatment with acupuncture, drugs and physiotherapy, and was admitted to the hospital and underwent CT-guided minimally invasive interventional facial nerve radiofrequency treatment, and the spasm disappeared 1 day after treatment, with no recurrence after 3 months of follow-up. Area spasm knowledge popularization: facial muscle spasm is manifested as involuntary twitching of facial muscles, involuntary closing of the eyes on the sick side when showing teeth, contraction of the frontal muscles on the patient’s side when trying to close the eyes, tearing when eating irritating food, flushing of the temporal skin, local heat, sweat secretion and other phenomena. Causes of facial muscle spasm: 1, vascular factors: mainly due to the formation of vascular loops or ectopic compression of the anterior inferior cerebellar artery and posterior inferior cerebellar artery to the facial nerve, but also may be due to other variant large arteries such as vertebral artery, basilar artery pulsatile compression. 2. Non-vascular factors: Non-vascular occupying lesions in the pontocerebellar angle, such as granulomas, tumors and cysts, can also produce facial muscle spasm. Other factors such as: A. Displacement of normal blood vessels due to occupancy. B. Direct compression of the facial nerve by the occupancy. C, the influence of abnormal blood vessels of the occupancy itself such as seminal artery malformation, meningioma, aneurysm, etc. 3, the presence of compression factors in the exiting brainstem area of the facial nerve is a possible factor in the generation of facial muscle spasm. Facial muscle spasm treatment: Facial muscle spasm is mostly caused by local blood vessels that nourish the nerve due to inflammation, cold and other factors and spasm, neural tissue edema, compression, early use of facial nerve block, nerve dehydration, nerve repair and other treatments to promote local edema, inflammation, and promote the recovery of facial nerve function as soon as possible. For patients with intractable spasm, minimally invasive treatment such as facial nerve radiofrequency or nerve decompression can be performed.
