to reduce hemangioma size; however, whether a difference in safety exists is not clear. All of these results were based on moderate- to low-quality evidence, thus further randomized, controlled trials with large populations of children are needed to further evaluate these therapies. This review concluded that for now, no evidence challenges oral propranalol as the standard systemic therapy for treatment of these lesions. Other systemic therapies which may be effective for IH treatment include vincristine, interferon, and other agents with antiangiogenic properties. Vincristine, which requires central venous access for administration, is traditionally used as a chemotherapy agent, but has been demonstrated to have efficacy against hemangiomas and other childhood vascular tumors, such as kaposiform hemangioendothelioma and tufted angioma. Interferon-alpha 2a and 2b, given by subcutaneous injection, has shown efficacy against hemangiomas, but may result in spastic diplegia in up to 20% of treated children. These agents are rarely used now in the era of beta-blocker therapy. Intralesional corticosteroid (usually triamcinolone) injection has been used for small, localized hemangiomas, where it has been demonstrated to be relatively safe and effective. Injection of upper eyelid hemangiomas is controversial, given the reported risk of retinal embolization, possibly related to high injection pressures. Topical timolol maleate, a nonselective beta blocker available in a gel-forming solution approved for the treatment of glaucoma, has been increasingly recognized as a safe and effective off-label alternative for treatment of small hemangiomas. It is generally applied two to three times daily. Surgery Surgical excision of hemangiomas is rarely indicated, and limited to lesions which fail medical therapy (or when it is contraindicated), which are anatomically distributed in a location which is amenable to resection, and in which resection would likely be necessary and the scar will be similar regardless of timing of the surgery. Surgery may also be useful for removal of residual fibrofatty tissue (following hemangioma involution) and reconstruction of damaged structures. Laser Laser therapy, most often the pulsed dye laser (PDL), plays a limited role in hemangioma management. PDL is most often used for treatment of ulcerated hemangiomas, often in conjunction with topical therapies and wound care, and may speed healing and diminish pain. Laser therapy may also be useful for early superficial IHs (although rapidly proliferating lesions may be more prone to ulceration following PDL treatment), and for the treatment of cutaneous telangiectasias which persist following involution. Prognosis In the involution phase, an IH finally begins
