Platysma synkinesis and botulinum toxin

What is it about?

Facial synkinesis is a well-known disabling occurrence after severe facial palsy. Platysma muscle, innervated by the facial nerve, can be involved in synkinesis as well. The aim of our study was to evaluate the presence of platysma synkinesis and their clinical evolution after onabotulinumtoxinA (Botox®) injections.

Why is it important?

Platysma involvement represents a recurring and symptomatic problem in patients affected by synkinetic recovery after facial palsy, but has been little investigated so far. In this study data of sixty-nine patients are reported, for a total of 124 sessions. After onabotulinumtoxinA injections a reduction in platysma synkinesis and related symptoms occurred.
