What is vocal cord paralysis in children?

Vocal cord paralysis develops when one or both of the vocal cords (vocal folds) fail to move. The vocal cords are two small muscle and tissue bands inside the larynx (voice box). Their movement is essential in breathing, speaking, and closing off the airway during swallowing. When they are paralyzed, they cannot open or close properly, leading to various symptoms.

What are the symptoms of vocal cord paralysis in children?

Symptoms vary depending on whether one (unilateral) or both (bilateral) vocal cords are affected, and the child’s age.

Unilateral Vocal Cord Paralysis (One cord):

• Hoarse voice
• Breathiness
• Weak cry (in babies)
• Noisy breathing (stridor), especially with exertion or crying
• Coughing or choking while eating
• Chronic respiratory infections

Bilateral Vocal Cord Paralysis (Both cords): A more severe condition where both cords remain partially closed, blocking the airway.

• Severe breathing difficulty requiring urgent medical attention
• Loud, high-pitched stridor
• Weak or absent cry
• Cyanosis (bluish skin from lack of oxygen)
• Feeding and aspiration issues

Why does vocal cord paralysis occur in children?

There may be multiple causes, or it can be idiopathic (unknown). Common causes include:

• Birth trauma: Often damages the vagus or recurrent laryngeal nerve during delivery.
• Neurological disorders: Such as Chiari malformation, hydrocephalus, or other brain abnormalities.
• Surgery: Operations on the chest or neck may unintentionally injure vocal cord nerves.
• Infections: Certain viral infections may involve the nerves.
• Tumors: Rarely, tumors in the head, neck, or chest may press on nerves.
• Idiopathic: No identifiable cause is found in many cases.

How is vocal cord paralysis in children diagnosed?

Diagnosis typically includes:

• Detailed medical history including birth, surgeries, illnesses
• Physical exam of breathing, voice, and neurological signs
• Laryngoscopy: A flexible or rigid scope is used to view vocal cord movement during breathing and phonation
• MRI: To identify neurological or structural causes
• Esophagram: A barium swallow test to evaluate for aspiration
• Neurologic evaluation: If a brain-related cause is suspected

What is the treatment for vocal cord paralysis in children?

Treatment depends on the cause, severity, and whether one or both cords are paralyzed.

Observation: Many unilateral cases recover on their own within 6–12 months, especially those caused by birth trauma.

Supportive care includes:

• Feeding modifications to reduce aspiration risk
• Voice therapy with a speech-language pathologist

Surgical treatments:

For Bilateral Vocal Cord Paralysis:

• Tracheostomy: Creates an alternate airway in severe cases
• Posterior cordotomy or arytenoidectomy: Removes part of the vocal cord/cartilage to widen the airway
• Laryngeal reinnervation: Newer surgery that re-routes a nerve to restore movement or tone

For Unilateral Vocal Cord Paralysis (if persistent):

• Injection laryngoplasty: Bulks up the paralyzed cord for better closure
• Medialization thyroplasty: Surgically pushes the paralyzed cord to the midline to improve voice and reduce aspiration

What is the prognosis for children with vocal cord paralysis?

• Unilateral cases, especially from birth trauma, often improve over time. Many children recover voice and feeding function with minimal intervention.
• Bilateral cases have a more guarded prognosis. Surgical procedures may improve breathing, but some children may require long-term tracheostomy. Voice and feeding may also be affected.

Can vocal cord paralysis recur in children?

Recurrence is uncommon if the underlying issue is resolved (e.g., after viral recovery or tumor removal). If related to ongoing neurological disorders, new or worsening paralysis may occur. Postoperative paralysis may rarely recover but is often permanent.

What are the long-term implications for a child with vocal cord paralysis?

• Voice issues like hoarseness or breathiness
• Breathing challenges, especially in bilateral paralysis
• Feeding and aspiration risks
• Developmental delays in some cases due to neurological or respiratory complications
• Psychosocial impact, especially in older children—voice or breathing differences can affect self-esteem
