Voice disorders can have a significant negative impact on a person's daily life and quality of life. Vocal cord paralysis, as one of many disorders, occurs due to damage to the recurrent laryngeal nerve (RLN), which consequently fails to innervate the vocal cord, resulting in its paralysis. It can be unilateral or bilateral, with unilateral being much more common and it falls within the scope of a speech therapist's work. Paralysis causes dysphonia and, in some cases, dysphagia. The symptoms of dysphonia are very prominent and may manifest as breathiness, roughness, general hoarseness, and the person often develops hyperfunctional compensatory mechanisms. Given the long course of the RLN, it can be injured in various ways, making the etiology very diverse, and sometimes the cause is unknown. After assessment and diagnosis, involving both an otorhinolaryngologist and a speech and language pathologist, the appropriate therapy is selected. In addition to medical treatment, the involvement of an SLP for voice therapy is encouraged to optimize voice rehabilitation outcomes. Voice therapy does not necessarily have to be conducted only postoperatively; preoperative therapy is common in this area and can sometimes eliminate the need for invasive procedures. In most cases, speech therapy combines behavioral techniques focused on different aspects of voice production and indirect techniques such as providing vocal hygiene instructions. The literature mostly shows positive outcomes of voice therapy, however there are issues with heterogeneity between studies.
