Study summary

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.

Read the detailed description

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • MRI examination of the head confirmed the medullary infarction.
  • Those who have not significantly improved swallowing function after standardized rehabilitation treatment for more than 2 weeks (FOIS remains unchanged or decreases)
  • Video-fluroscopic swallowing study (VFSS) indicated incomplete/non-opening of the cricopharyngeal muscle
  • Based on Fiberoptic endoscopic evaluation of swallowing, the hyoid bone moves upward more than half the height of the C3 cone
  • Vital signs are stable
  • The patient himself or his family voluntarily signed a written form.

Exclusion criteria

Exclusion Criteria:

  • Brain MRI showed that there were lesions in other areas outside the medulla oblongata
  • People who have suffered from stroke in the past
  • Patients with severe cognitive impairment, mental illness and severe cardiopulmonary disease
  • Abnormal throat structure
  • Malignant tumor patient
  • Patients with other neuromuscular diseases
  • Infection or wound at the injection site
  • Botulinum toxin allergic person
  • Hemorrhagic tendency and coagulation dysfunction
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Functional 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

  2. 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

Secondary outcomes

  1. 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

  2. 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

  3. 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

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 14, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
