Spasmodic laryngitis, also known as spasmodic dysphonia, is a voice disorder that affects the muscles in the throat responsible for speaking. It causes sudden and involuntary contractions of the vocal cords, leading to a strained or shaky voice. There are several synonyms for spasmodic laryngitis, including adductor spasmodic dysphonia, abductor spasmodic dysphonia, and laryngeal dystonia. These terms describe the different types of spasms that can occur in the voice box, leading to a range of symptoms from breathy or whispery speech to a strained and creaky voice. While there is no known cure for spasmodic laryngitis, treatments such as speech therapy and Botox injections can help manage the symptoms and improve vocal function.
