Muscle Tension Dysphonia/Vocal Strain

Muscle Tension Dysphonia (MTD), or vocal strain, are both terms used to describe a voice disorder that is associated with the way a person uses their voice, where excessive muscular effort is used for to produce voice. MTD can either be the primary diagnosis, when nothing else is seen to be problematic in the larynx (voice box), or it may be a compensation for structural difficulties, such as polyps, cysts or glottal incompetence (where the vocal folds don’t fully meet when speaking).
