New Botox-Like shot may give voice disorder patients months of relief

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 previously been helped by standard Botox injections received a single DAXI injection into their voice box muscles. The goal was to see if DAXI could provide longer-lasting voice improvement, potentially reducing the need for repeat injections every few months.
