About this trial

This is an interventional treatment trial for Hemifacial Spasm focused on measuring botulinum toxin A

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • clinical diagnosis of hemifacial spasm
  • Scott grading III to IV
  • hemifacial spasm duration of half or more years
  • last botulinum toxin A application at least 3 months before the start of the study

Exclusion Criteria:

  • history of facial trauma, congenital facial asymmetry, facial nerve microsurgical decompression
  • bilateral hemifacial spasm
  • allergies to botulinum toxin A or to any component of the drug
  • previous treatment with botulinum toxin A fewer than 3 months
  • the use of drugs that could interfere with neuromuscular transmission or spasm

Arms of the Study

Arm 1

Arm 2

Arm Type

Placebo Comparator

Experimental

Arm Label

unilateral injection group

bilateral injection group

Arm Description

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

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.

Outcomes

Primary Outcome Measures

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

Secondary Outcome Measures

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

5. Study Description

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.
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.
