Unilateral vocal cord paralysis UVCP in children is a rare and challenging disorder for the pediatric otolaryngologist. The overall etiology differs from that in adults, iatrogenic causes are the commonest, followed by traumatic - birth or intubation trauma and neurologic causes. Management strategies used for adults have evolved and been utilized in children, with increasing reports of surgical intervention over the last decade. However, number of children treated remains small with no long-term follow-up.
Treatment of Unilateral Vocal Fold Immobility
Idiopathic bilateral vocal cord paralysis in infants: Case series and literature review
Bilateral paralysis is a severe condition and often remains of unknown etiology. We report our experience of congenital idiopathic bilateral vocal fold paralysis in newborns and infants, and discuss the therapeutic options. Study design: Retrospective review. Methods: A retrospective review was carried out at a single tertiary referral center over a year period of children presenting with congenital idiopathic bilateral laryngeal paralysis CIBP.
Vocal cord paralysis: anatomy, imaging and pathology
Skip to main content. Vocal fold paralysis also known as vocal cord paralysis is a voice disorder that occurs when one or both of the vocal folds don't open or close properly. Single vocal fold paralysis is a common disorder. Paralysis of both vocal folds is rare and can be life threatening. The vocal folds are two elastic bands of muscle tissue located in the larynx voice box directly above the trachea windpipe see figure.
Vocal cord paresis , also known as recurrent laryngeal nerve paralysis or vocal fold paralysis , is an injury to one or both recurrent laryngeal nerves RLNs , which control all muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing. The primary larynx-related functions of the mainly efferent nerve fiber RLN, include the transmission of nerve signals to the muscles responsible for regulation of the vocal folds ' position and tension to enable vocalization, as well as the transmission of sensory nerve signals from the mucous membrane of the larynx to the brain. A unilateral injury of the nerve typically results in hoarseness caused by a reduced mobility of one of the vocal folds. It may also cause minor shortages of breath as well as aspiration problems especially concerning liquids.
