A case of subglottic hemangioma: a new technique of surgical removal.

Congenital malformation of the larynx are life-threatening anomaly for newborns and infants. Although tumorous lesions in these malformations (especially subglottic hemangioma) are extremely rare, when they do occur some definitive attempts should be made to treat them in infancy. This report concerns a case of subglottic hemangioma with marked stridor and sternal retractions which had begun in the third month of age in a six month-old male. In the excision of the hemangioma a new technique is employed. That is: the excision through the laryngofissure was made under surgical microscope. Assuming that careful removal of the subepithelial hemangioma and closure of the overylaying epithelia would help to maintain the mucosa and thereby avoid excessive scarring, the hemangiomatous tissue was completely removed while preserving the overlaying epithelial layer.
