What issue does unilateral vocal fold paralysis primarily present?

Unilateral vocal fold paralysis primarily presents with issues related to laryngeal closure. This condition occurs when one of the vocal folds cannot move properly, leading to an incomplete closure of the larynx during phonation. As a result, individuals may experience a range of vocal disturbances, including hoarseness, breathiness, and reduced vocal intensity. The inability of the vocal folds to come together fully affects the efficiency of sound production and can also compromise airway protection during swallowing, increasing the risk of aspiration.

While articulation, speech fluency, and breath support can be impacted as a secondary consequence of vocal fold paralysis, the main issue at hand is the inability of the affected vocal fold to close effectively. Understanding this primary issue is crucial for diagnosis and treatment, as speech-language pathologists will often focus on improving vocal fold function and facilitating better laryngeal closure to enhance communication and safety.
