Infantile subglottic hemangiomas. An update.

Between 1913 and 1985, 323 cases of infantile subglottic hemangiomas have been reported in the English language literature. The purpose of this study is to review these cases, to report The Johns Hopkins Hospital experience with ten additional cases, and to compare the various methods of treatment in an attempt to identify the regimens associated with the best outcome. The majority of the patients presented before the age of 6 months with respiratory distress, most commonly inspiratory stridor. There was a 2:1 female to male preponderance. The diagnosis was established by endoscopy in the majority and confirmed by biopsy in one third, without serious bleeding complications. A plethora of treatment methods have been described, including the following: corticosteroids, tracheotomy, radiation therapy, radioactive implant therapy, surgical excision, cryotherapy, and carbon dioxide laser. These methods were reviewed and their results compared to our own. We conclude that several methods are effective, each having its advantages and disadvantages. We believe that immediate tracheotomy should be performed in cases with severe airway obstruction. Smaller lesions may be vaporized with the carbon dioxide laser without tracheotomy if postoperative care is provided in a pediatric intensive care unit. Corticosteroids may be used alone or in combination with other modalities. External radiation therapy and injection of sclerosing agents are not advised.
