Vocal Fold Paralysis

Vocal fold paralysis is a condition that can significantly impact your ability to speak, breathe comfortably, and swallow safely. At AOO | ENT Specialists of the Rockies, we understand how distressing voice changes or breathing difficulties can be. Our experienced ENT team provides comprehensive evaluation and advanced treatment options to help restore function and improve quality of life.

What Is Vocal Fold Paralysis?

Vocal fold paralysis occurs when one or both vocal folds (also called vocal cords) cannot move properly due to nerve dysfunction, joint disruption, or tumor involvement. The vocal folds are located in the larynx (voice box) and play a critical role in producing sound, protecting the airway during swallowing, and regulating airflow for breathing.

When a vocal fold is paralyzed, it may remain partially or completely open or closed. This can lead to a weak, breathy voice, difficulty projecting speech, problems swallowing food or liquids, and, in some cases, shortness of breath. Vocal fold paralysis may affect one side (unilateral) or both sides (bilateral), with symptoms varying depending on severity.

What Causes Vocal Fold Paralysis?

Vocal fold paralysis is most often caused by damage or disruption to the nerves that control the larynx. Common causes include:

• Surgical injury: Procedures involving the neck, chest, thyroid, spine, or heart can sometimes affect the recurrent laryngeal nerve.
• Viral infections: Certain viral illnesses may cause inflammation or temporary nerve damage.
• Nerve injury or trauma: Accidents or direct trauma to the neck or chest.
• Tumors or growths: Masses in the larynx, neck, chest, or brain may compress the nerves controlling vocal fold movement or directly impact the vocal folds
• Neurological conditions: Disorders such as stroke or neurodegenerative disease.
• Idiopathic cases: In some patients, no clear cause is identified.

Understanding the underlying cause is essential for determining the most effective treatment approach.

Symptoms of Vocal Fold Paralysis

Symptoms can range from mild to severe and may include:

• Hoarseness or a weak, breathy voice
• Voice fatigue or difficulty speaking for long periods
• Reduced ability to project the voice
• Frequent throat clearing
• Choking or coughing when swallowing
• Sensation of food or liquid “going down the wrong way”
• Shortness of breath, especially during exertion
• Noisy breathing (in bilateral cases)

If symptoms persist for more than four weeks, evaluation by an ENT specialist is strongly recommended.

How Vocal Fold Paralysis Is Diagnosed

Early diagnosis plays a crucial role in protecting the airway and improving long-term outcomes. At AOO | ENT Specialists of the Rockies, diagnosis may include:

• In-office laryngoscopy and stroboscopy to visualize vocal fold movement
• Voice evaluation to assess sound quality and vocal strength
• Imaging studies such as CT or MRI scans to evaluate the nerve pathway and laryngeal architecture
• Swallowing assessment when aspiration is a concern

This comprehensive approach allows our specialists to pinpoint the cause and tailor treatment to each patient’s needs.

Treatment Options at AOO | ENT Specialists of the Rockies

Treatment for vocal fold paralysis depends on the cause, severity of symptoms, and whether nerve recovery is expected. Our team takes a personalized, patient-centered approach, often combining multiple therapies for optimal results.

Voice Therapy

Voice therapy with a speech-language pathologist is sometimes offered. Therapy focuses on strengthening the surrounding muscles, improving breath support, and learning safe swallowing techniques.

Injection Laryngoplasty

Injection laryngoplasty involves placing a filler material next to the paralyzed vocal fold to help it move closer to the midline.

• Temporary injections are often used when nerve recovery is expected.
• Longer-lasting injections may be recommended for more persistent paralysis.

This minimally invasive procedure can significantly improve voice quality and swallowing function immediately.

Medialization Thyroplasty

For patients with long-term or permanent vocal fold paralysis, medialization thyroplasty may be recommended. This surgical procedure places a small implant through the thyroid cartilage to reposition the vocal fold, providing lasting voice improvement and airway protection.

Reinnervation Surgery

Reinnervation procedures aim to restore nerve input to the paralyzed vocal fold. While movement may not fully return, preservation of muscle tone can enhance voice strength and stability over time. This option is often considered in select patients, particularly younger individuals.
