Spastic squint is a slowly progressive disease of unknown etiology, starting with neck discomfort, a “drop pillow”, neck stiffness, forced head position, and head flexion to the left or right. The disease itself does not usually cause death. However, the patient’s quality of life is severely affected and extremely painful, and some patients even suffer from depression as a result. A small number of patients may recover spontaneously. Some patients can get Botox to relieve the problem, but many patients feel that the effect of Botox is short-lived and hope to find a treatment method that can sustain the effect. Since the application of the surgical treatment of the brain pacemaker, it has brought a blessing to many patients with spastic squint, and more and more patients are now receiving the surgical treatment of the brain pacemaker. According to the doctor, the principle of pacemaker surgery is to regulate the abnormal impulses of neurons in the brain in order to improve the disease. The surgical procedure includes two steps: implantation of stimulating electrodes and implantation of neurostimulator. In the pre-surgery stage, a stereotactic head frame is installed on the painted head, magnetic resonance imaging is done, and under the high-resolution magnetic resonance image, the neural nuclei needed for the surgery are determined and the location of the target point is calculated, and after the positioning is completed, the patient enters the operating room. Two holes are punched in the patient’s head, an electrophysiological recording system is inserted, the surgical target is accurate, and then a brain pacemaker stimulation electrode is inserted, and then a stimulation generator is implanted, usually under the clavicle or in the armpit. After the surgery is completed, the patient recovers for a period of time, comes to the hospital for brain pacemaker turn-on, sets the parameters, adjusts to the appropriate parameters, the patient is comfortable, and the symptoms improve. This procedure is minimally invasive, relatively safe, and reversible and adjustable to enable the patient to remain in a good state and be able to live and work better.
