Which voice disorder may result from conditions like laryngeal cancer or vocal nodules?

The selection of structural as the correct answer relates to the nature of voice disorders that result from physical changes or abnormalities in the larynx or other structures involved in voice production. Structural voice disorders occur when there is a tangible alteration in the anatomy of the vocal folds or the surrounding tissues, which can happen due to conditions such as laryngeal cancer or the presence of vocal nodules. These nodules are benign growths that form on the vocal cords due to vocal abuse or misuse, which contribute to a change in voice quality.

In the case of laryngeal cancer, the cancerous growth can affect the vibratory function of the vocal folds, leading to hoarseness, breathiness, or loss of voice, all indicative of a structural disorder. Understanding that structural problems involve physical obstructions or changes in the vocal mechanism is essential in distinguishing them from functional disorders, which are related to behavioral or psychological issues, and neurological disorders, which stem from nerve or muscle problems affecting voice production.

Thus, recognizing that structural disorders are linked to identifiable changes in laryngeal anatomy clarifies why this answer is appropriate when discussing the consequences of specific medical conditions affecting the voice.
