NCT03306940

Brief Summary

Hemifacial spasm patients who received botulinum toxin A injection were divided into two groups. Group A received unilateral injection while group B received bilateral injection. Patients completed follow-up A researcher record facial videos and analyzed facial symmetry and completed 3 scales.

Outcome Measures

Primary Outcomes (1)

  • Sunnybrook Facial Grading System

    Sunnybrook Facial Grading System consists of resting symmetry, symmetry of voluntary movement and synkinesis. Total score = Symmetry of voluntary movement score - Resting symmetry score - Synkinesis score

    up to 6 months

Secondary Outcomes (4)

  • Symmetry Scale for Hemifacial Spasm

    up to 6 months

  • Facial Clinimetric Evaluation Scale

    up to 6 months

  • The effective duration of botulinum toxin A

    up to 6 months

  • Adverse events

    up to 6 months

Study Arms (2)

unilateral injection group

PLACEBO COMPARATOR

Patients of unilateral group were injected botulinum toxin type A to the affected hemiface.

Drug: Botulinum Toxin Type A

bilateral injection group

EXPERIMENTAL

Patients of bilateral group were injected botulinum toxin type A to the affected hemiface and normal hemiface. The intervention of the bilateral group was that the normal side was injected.

Drug: Botulinum Toxin Type A

Interventions

patients were injected to the normal side with dose of 1.25 units/per site

Also known as: Chinese botulinum toxin type A
bilateral injection groupunilateral injection group
