About this study

Official title: Does Bilateral Botulinum Toxin A in Patients With Hemifacial Spasm Improve Facial Symmetry Unilateral and Bilateral Injection of Botulinum Toxin A in Patients With Hemifacial Spasm? A Prospective, Randomized, Controlled Study

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.

Read the detailed description

Hemifacial spasm patients who received botulinum toxin A injection were divided into two groups.Patients of unilateral group were injected to the affected side and the dose of botulinum toxin A was 2.5-3.75 units/per site. Patients of bilateral group were injected to the affected side with dose of 2.5-3.75 units/per site and the normal side was injected with dose of 1.25 units/per site.

3 scales for measurement were used.

Study groupRoleWhat they receive
unilateral injection groupPlacebo comparatorPatients of unilateral group were injected botulinum toxin type A to the affected hemiface.
Receives: Drug: Botulinum Toxin Type A
bilateral injection groupExperimentalPatients 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.
Receives: Drug: Botulinum Toxin Type A

What is being measured

The primary outcome is the main question the study is designed to answer.

  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

    Measured: up to 6 months

Secondary outcomes (4)
  1. Symmetry Scale for Hemifacial Spasm

    Symmetry Scale for Hemifacial Spasm consists of resting symmetry and symmetry of voluntary movement. Total score =Resting symmetry score + Symmetry of voluntary movement score

    Measured: up to 6 months

  2. Facial Clinimetric Evaluation Scale

    Facial Clinimetric Evaluation Scale consists of six parts:facial movement,facial comfort,oral function,eye comfort,lacrimal control and social function. Total score = facial movement + facial comfort + oral function + eye comfort + lacrimal control + social function.

    Measured: up to 6 months

  3. The effective duration of botulinum toxin A

    degree of amelioration in spasm and the effective duration of botulinum toxin A

    Measured: up to 6 months

  4. Adverse events

    Adverse events, including stiff face, difficulty drinking and eating, difficulty controlling parotid and so on.The onset and duration of adverse events.Whether to take intervention to ameliorate adverse events and the efficacy of the intervention

    Measured: up to 6 months
