Unilateral Vocal Fold Immobility in Children.

Unilateral vocal fold paralysis (UVFP) in children may cause dysfunction in voice, swallowing, and breathing, thus influencing all components of laryngeal function. UVFP in children is usually the result of iatrogenic injury. The approach to patients with suspected UVFP should involve a detailed patient history, a focused physical examination with flexible nasopharyngoscopy, and relevant imaging if the cause of UVFP is uncertain. Management aims to strengthen voice, decrease aspiration, and improve quality of life. Laryngeal reinnervation is becoming more common, potentially offering permanent improvement in vocal and swallowing function through increasing bulk and tone to the paralyzed vocal fold.
