Dysphagia is an important complication in patients with medullary infarction, the incidence rate is 57%-69%. Compared with other brain infarctions, the medulla oblongata involves multiple swallowing-related nerve nuclei, and the possibility of brain remodeling after injury is small. Dysphagia has become a prominent clinical problem in patients with medullary infarction, which can lead to malnutrition, decrease the quality of life of patients and affect the prognosis of the disease. Solving this clinical problem is particularly important for patients with medullary infarction. The incidence of UES opening disorder in patients with medullary infarction is as high as 80%, and the clinical problem of UES opening disorder is enthusiastically studied at home and abroad. At present, the intervention measures include balloon dilatation, surgical incision and botulinum toxin injection. Balloon dilatation is easy to cause mucosal edema and damage, and cricopharyngeal myotomy often has complications such as local infection, massive hemorrhage and local nerve injury. There is no significant difference between the success rate of UES botulinum toxin injection and surgical incision. Among the above measures, UES botulinum toxin injection has a good clinical application prospect, but the drug dosage and injection method are still not unified in clinic. In particular, how to accurately locate has become a hot topic in current research. On this basis, this study uses ultrasound combined with balloon localization to inject UES botulinum toxin and make clinical observation.
Under the ultrasound combined with balloon fixation, two injection sites were selected from the left upper esophageal sphincter, and 30U was injected respectively, and one injection site was selected from the right side, and 30U was injected. In addition, the patient also received routine swallowing training once a day for 30 minutes.

RECRUITINGFunctional Oral Intake Scale
According to whether the patient can eat by mouth and the degree of dependence on nasal feeding tube, it is divided into 7 grades, corresponding to 1-7 points respectively. The higher the score, the better the swallowing function.
Time frame: day 1 ，day 14，day28 and day 180
Rosenbek penetration-aspiration scale
Based on the results of Videofluroscopic swallowing study (VFSS), the cases of leakage and aspiration were divided into 8 grades, corresponding to 1-8 points respectively. The higher the score, the better the swallowing function.
Time frame: day 1 and day 14
Murray secretion scale
Based on Fiberoptic endoscopic evaluation of swallowing (FEES), the accumulation position of oropharyngeal secretions was described and divided into 4 grades. The higher the score, the worse the swallowing function.
Time frame: day 1 and day 14
yale pharyngeal residue severity rating scale
Based on Fiberoptic endoscopic evaluation of swallowing (FEES), the main indicators include the location of the residue (epiglottic valley and pyriform sinus) and the amount of residue, which is divided into 5 grades. The higher the score, the worse the swallowing function.
Time frame: day 1 and day 14
fiberoptic endoscopic dysphagia severity scale
Based on Fiberoptic endoscopic evaluation of swallowing (FEES), Eat different foods and observe whether penetration aspiration and protective reflex occur. The highest score is 6, which means that saliva accumulates with penetration or aspiration, and the lowest score is 1. When eating soft solid food, there is no leakage or aspiration, and there is little or moderate residue in epiglottic valley or pyriform sinus. The higher the score, the worse the swallowing function.
Time frame: day 1 and day 14
