Vocal cord injection in children with unilateral vocal cord paralysis

Unilateral vocal cord paralysis (UVCP) in children is uncommon and rarely leads to serious sequelae. However, on rare occasions, it can present with severe aspiration and dysphonia. Several therapeutic techniques have been used in adults with UVCP, but the reported alternatives in children have been much more limited. Observation and speech therapy are the standard treatment. We describe three children with UVCP and severe aspiration who were treated with vocal cord injection. The treatment indications, clinical courses, and outcomes of the three cases are detailed. The injection of vocal cords in children is discussed, with an emphasis on those aspects unique to the management of UVCP in pediatric patients. Alternative surgical treatment modalities are also presented. Vocal cord injection is an effective and viable therapeutic option for the management of UVCP in certain pediatric patients with severe aspiration and dysphonia.
