    Hemifacial spasm is characterized by involuntary contractions on one side of the face, typically caused by vascular compression at the nerve exit zone.

  • 2

    Current grading systems for hemifacial spasms are complex and overlapping, making patient self-assessment essential for evaluating symptom changes.

  • 3

    Facial recognition and tracking technologies can objectively quantify and classify hemifacial spasms, improving treatment outcome assessments.

  • 4

    The study utilized preoperative video analysis to measure spasm amplitude and frequency using advanced facial tracking software and techniques.

  • 5

    Standardized measurement parameters were established to evaluate hemifacial spasms, focusing on the percentage change in facial distances during contractions.
