Position of the hyoid and larynx in people with muscle tension dysphonia.

Objectives/hypothesis: To determine whether radiographic measures of hyoid position, laryngeal position, and hyolaryngeal space during phonation were different for people with primary muscle tension dysphonia (MTD) as compared to control participants without voice disorders.

Study Design: Prospective, quasi-experimental research design.

Methods: Twenty participants, 10 with primary MTD and 10 without voice disorders who were age and sex matched were studied radiographically while producing phonation.
