Vocal cord paresis

Vocal cord paresis, also known as vocal fold paresis, is a health condition characterized by the weakness or paralysis of one or both vocal cords. This condition can significantly affect a person's ability to speak and breathe.

Causes

Vocal cord paresis can be caused by a variety of factors. These include nerve damage due to surgery, viral infections, neurological disorders, or stroke. In some cases, the cause of vocal cord paresis may be unknown, a condition referred to as idiopathic vocal cord paresis.

Symptoms

The symptoms of vocal cord paresis can vary depending on the severity of the condition and which vocal cord is affected. Common symptoms include hoarseness, breathy voice, difficulty speaking loudly, voice fatigue, and frequent throat clearing. In severe cases, individuals may experience difficulty swallowing or breathing.

Diagnosis

Diagnosis of vocal cord paresis typically involves a physical examination and a review of the patient's medical history. Additional tests such as laryngoscopy, electromyography, and imaging studies may also be used to confirm the diagnosis and determine the extent of the paresis.

Treatment

Treatment for vocal cord paresis often involves speech therapy to improve voice quality and control. In some cases, surgical intervention may be necessary to reposition the affected vocal cord and improve voice and swallowing function. Medications may also be used to treat underlying conditions contributing to the paresis.

Prognosis

The prognosis for individuals with vocal cord paresis varies depending on the underlying cause and the severity of the condition. With appropriate treatment, many individuals can regain normal or near-normal voice function.
