There are three main type of treatments: medical treatments, voice therapy and surgical treatments. When necessary, certain voice disorders use a combination of treatment approaches. A medical treatment involves the use of botulinum toxin (botox) or anti-reflux medicines, for example. Botox is a key treatment for voice disorders such as Spasmodic Dysphonia. Voice therapy is mainly used with patients who have an underlying cause of voice misuse or abuse. Laryngologists also recommend this type of treatment to patients who have an organic voice disorder - such as vocal fold nodules, cysts or polyps as well as to treat functional dysphonia. Certain surgical treatments can be implemented as well - phono microsurgery (removal of vocal fold lesions performed with a microscope), laryngeal framework surgery (the manipulation of the voice box), as well as injection augmentation (injection of substance to vocal folds to improve closure). Surgical treatments may be recommended for patients having an organic dysphonia.
