Introduction: Bilateral vocal cord immobility (BVCI) is a leading cause of stridor and airway obstruction in neonates which may arise idiopathically, as a result of birth trauma, or in the setting of Central nervous system lesions such as Arnold-Chiari malformation. Although many children with BVCI may be managed conservatively, surgical intervention may be necessary in those patients with ongoing upper airway obstruction. Many interventions have been described including, tracheostomy, cordotomy, cricoid splitting procedures, and arytenoidectomy. Vocal cord suture lateralization has the advantage of being both reversible and less morbid than other surgical interventions for BVCI. This study describes a novel variation of the suture lateralization procedure which aids in correct placement of the suture thus minimizing multiple needle passes and associated laryngeal edema.
Methods: A retrospective chart review was undertaken of five patients undergoing suture lateralization of the vocal cord for BVCI at a single institution over a 10 year period. Post-operative voice and swallow outcomes were recorded.
Results: Of five patients undergoing this procedure four returned to normal diet. One was diagnosed with a progressive neurological disorder and was persistently fed via gastrostomy tube. Three of the five patients spontaneously recovered vocal cord function and went on to have normal voice after suture removal.
Conclusion: Suture lateralization is a safe and effective means of alleviating upper airway obstruction in BVCI. It has the advantages of being reversable and minimally invasive; however, optimal suture placement is both vital and challenging. The novel technique described in this study allows identification of landmarks as and aid to suture placement thus reducing the need for multiple needle passes into the lumen of the larynx.
