    Abstract:
    Infantile subglottic hemagioma is a rare vascular malformation involving the subglottic larynx and although present from birth, symptoms will not be noted until later in infancy (due to tendency to enlarge). Typically presents with a progressive crouplike illness that begins a few weeks after birth and the infant develops inspiratory stridor, which becomes expiratory as the obstruction increases. Although benign lesions which involute spontaneously, they may demand the attention of an ENT surgeon to maintain a secure airway. We report a case of a 3-month-old female patient (full term, normal delivery) who was referred to us for investigation of respiratory distress. Endoscopic examination revealed a hemangioma at the left lateral wall of the subglottic larynx while the rest of the airway was normal. The infant was treated with a combination of steroids (dexamethazone 0.5 mg x 3 per os) and interferon A-2a (650.000 IU subcutaneously, every other day, for 12 months) and had fast improvement of her symptoms. Repeated endoscopy 3 months after the diagnosis reveal impressive remission of the subglottic hemangioma. Throughout the years, a variety of treatments have been proposed and utilised for subglottic hemangioma. Interfron 2-alpha, drug acting by interference with angiogenesis, is very effective in treating subglottic hemangiomas without the need for tracheostomy. Its side effects are generally not serious. As congenital subglottic hemangiomas have tendency towards spontaneous regression, conservative treatment seems more appropriate compared to more aggressive treatment that carry substantial risks of long term complications.
