AIM: To analyze the evolution in the management of airway infantile hemangioma(AIH) and to report the results from 3 pediatric tertiary care ***: A retrospective study of patients with diagnosis of AIH and treated in 3 pediatric tertiary care institutions from 1996 to 2014 was performed. RESULTS: Twenty-three patients with diagnosis of AIH were identified. Mean age at diagnosis was 6 mo(range, 1-27). Single therapy was indicated in 16 patients and 7 patients received combined therapy. Two therapeutic groups were identified: Group A included 14 patients who were treated with steroids, interferon, laser therapy and/or surgery; group B included 9 patients treated with oral propranolol. In group A, oral corticosteroids were used in 9 patients with a good response in 3 cases(no requiring other therapeutic option), the other patients required additional treatment options. Cushing syndrome was observed in 3 patients. One patient died of a fulminant sepsis. Open surgical excision and endoscopic therapy were performed in 11 patients(in 5 of them as a single treatment) with a response rateof 54.5%. Stridor persisted in 2 cases, and one patient died during the clinical course of bronchial aspiration. In group B, oral propranolol was used in 9 patients(in 8 of them as a single treatment) with a response rate of 100%, with an mean treatment duration of 7 mo(range, 5-10); complications were not observed. CONCLUSION: Our experience and the medical literature support the use of propranolol as a first line of treatment in AIH.
