A general term for surgical treatments aimed at improving vocal function. In addition to removal of vocal cord nodules, polyps, and benign tumors, and midline vocal cord fixation and intracordal injection for recurrent laryngeal nerve paralysis, various surgical methods for laryngeal cartilage have also been devised (called laryngeal functional surgery). These techniques are also used for repair and reconstruction after laryngectomy for malignant tumors. In this case, careful consideration must be given not only to vocal function, but also to respiratory function and the defense function of the lower airway during swallowing.
