Botulinum toxin A for spasmodic dysphonia

For the treatment of

Spasmodic dysphonia

Commissioning position

This intervention is commissioned if spasmodic dystonia:

  • is interfering with independent functioning (e.g. communication, nutritional intake) OR
  • is painful.

Summary of rationale

Botulinum toxin has been in longstanding use for the treatment of Spasmodic dysphonia. The limited evidence of its effectiveness mainly relates to the most common Adductor form of Spasmodic dysphonia. Suitable dosage of Botulinum toxin is determined individually after a titration period.

Surgical interventions have been studied but currently lack evidence of superior effectiveness.

Speech therapy is also used but is more likely to be effective alongside Botulinum toxin injections.
