Thyroplasty surgeries include a group of surgical techniques to treat spasmodic dysphonia/laryngeal dystonia by modifying the cartilage surrounding the larynx. These adjustable and reversible procedures involve manipulating the cartilage by implanting wedges or shims to hold the tissue in place. A number of variations of this procedure are currently used and are effective for restoration of the voice after paralysis or in changing the pitch of the voice.
