MUSCLE TENSION DYSPHONIA

External laryngeal muscles:Myelohyoid, sternohyoid, omohyoid,thyrohyoid, cricothyroid, digastrics- Laryngeal framework/position

- Otherwise normal larynx on endoscopy- Voice "gives out," weak and breathy. Adaptive compensationfrom glottic incompetence / excessive laryngeal muscle tension

Internal laryngeal muscles:Thyroarytenoid, cricothyroid,

cricoarytenoid- Sound production

Innervated by CN X
