Muscle tension dysphonia and adductor spasmodic dysphonia are regarded as different voice disorders. When voice symptoms and laryngeal endoscopic findings are similar or voice symptoms are lost during medical examination, it is difficult for therapists to differentiate between these two voice disorders. The role of the speech-language-hearing therapist in discriminating between them is to improve the functional factors by voice therapy and supplement the diagnosis. When attempting certain facilitation techniques in trial therapy, a good response suggests that voice therapy should be performed first. However, in cases where it is difficult to choose an appropriate facilitation technique or patients have psychological problems, intervention by a speech-language-hearing therapist may not be successful. It is important to collect and share the therapeutic effects on difficult-to-distinguish cases and collaborate with specialists in the psychosomatic medicine department.
