Which technique is NOT recommended for treating muscle tension dysphonia?

Vocal fold surgery is not recommended for treating muscle tension dysphonia because this condition is primarily related to the function and coordination of the muscles involved in voice production rather than a structural issue with the vocal folds themselves. Muscle tension dysphonia typically arises from excessive muscle tension in the laryngeal and surrounding areas, which can often be addressed through conservative, non-invasive techniques focused on vocal function and muscle relaxation.

In contrast, techniques such as yawn-sigh, laryngeal massage, and digital manipulation aim to alleviate tension and improve vocal function through more natural and therapeutic means. These approaches seek to reduce muscle strain by promoting relaxation and better vocal habits, which are essential steps in treating muscle tension dysphonia effectively.
