Summary

This study tested a new type of botulinum toxin injection (DAXI) for people with adductor spasmodic dysphonia, a condition that causes the voice to spasm and sound strained. 22 adults who had already been helped by standard Botox injections received one DAXI injection. The goal was to see if DAXI could ease voice symptoms and last longer than the usual 3-month treatment cycle.
