ClinConnect Summary

This clinical trial is investigating how advanced imaging techniques can help better understand and diagnose hemifacial spasm (HFS), a condition where one side of the face experiences involuntary muscle contractions. The researchers want to see if new methods of MRI, which create 3D images of the facial nerve and surrounding blood vessels, can provide clearer details about nerve compression caused by nearby blood vessels. They also aim to evaluate certain measurements of the facial nerve to see if they can predict how severe a patient's symptoms might be.

To be eligible for this study, participants should have been diagnosed with primary HFS, experiencing involuntary spasms on one side of their face for at least a year. People with other causes for their symptoms, such as tumors, or those with certain medical devices like pacemakers, will not be included. If you qualify and choose to participate, you can expect to undergo advanced MRI scans, which will help researchers gather important information about your condition to improve future treatment options.

Eligibility criteria

• Inclusion Criteria:
• • Primary HFS patients according to medical history and typical facial muscle spasms that are unilateral, involuntary, and had intermittent contractions innervated by the ipsilateral facial nerve. The patient has 1 year disease duration at least.
• Exclusion Criteria:
• • Secondary causes of HFS, such as tumors or cysts compressing the facial nerve in the cerebellar pontine cistern; Precarious general health status; Percutaneous lesions or surgical treatments; Cardiac pacemaker or metal implants.
