The most common type of facial spasm surgery is microvascular decompression, which includes the process of exposing the field, incising, taking bone flaps, and finding the facial nerve and responsible blood vessels. 1. Exposure of the surgical field: Before the surgery, the nurse will remove part of the patient’s hair behind the ear to facilitate the surgical operation. 2. Incision: After the surgeon washes his hands and disinfects the towel, he makes a small, long incision in the occipital bone behind the ear. 3. Bone flap removal: After the skin behind the ear is cut, the muscles, blood vessels and other tissues are separated, the occipital bone is exposed, and several small openings are drilled into the occipital bone with a milling drill, and then the bone flap is removed with a scalpel. 4. Finding the facial nerve and responsible blood vessels: After the bone flap is removed, the facial nerve and responsible blood vessels are found under the microscope. 5. Separate the blood vessels and responsible nerves: A special shock-absorbing material spacer is used to separate the responsible blood vessels from the nerves, and then the cranium is closed layer by layer to end the surgery. It should be noted that the speed of symptomatic improvement of postoperative myasthenia varies. Surgical treatment and postoperative management should be carried out under the guidance of specialized physicians.
