Protracted phonation with an improper style can cause laryngeal diseases or voice disorders, such as contact ulcer, vocal cord nodule, vocal cord polyp, phonasthenia ("myasthenia laryngis" by Jackson1), and so on (Brodnitz2,3; Froeschels4; Green5; Holinger and Johnston6; Jackson7; Jackson and Jackson8; Luchsinger and Arnold9; Murphy10; Peacher and Holinger11; von Leden and Moore12).
