Supplementary Material for: Topical Timolol Maleate 0.5% for Infantile Hemangioma: Its Effectiveness Compared to Ultrapotent Topical Corticosteroids - A Single-Center Experience of 278 Cases

<i>Background:</i> Infantile hemangioma (IH) may have implications on parental distress and cosmetic disfigurement. To date, ultrapotent corticosteroids are used as a treatment of choice for superficial IH. However, due to their side effects and sometimes lack of IH regression, it is necessary to find alternative topical therapies. Timolol maleate 0.5% solution and gel are nonselective β-blockers that could inhibit proliferation and trigger regression of IH. <i>Objective:</i> To evaluate the efficacy of topical ultrapotent corticosteroids and timolol maleate 0.5% solution and gel for superficial IH. <i>Patients and Methods:</i> The study design was prospective. Two hundred and seventy-eight patients diagnosed as having superficial IH were enrolled from the outpatient clinic of the Department of Dermatology and Venereology, Dr. Sardjito Hospital, Yogyakarta, Indonesia, from January 2009 to December 2014. Patients were divided into three groups: A = treated with topical ultrapotent corticosteroid, B = timolol maleate 0.5% solution and C = timolol maleate 0.5% gel. Patients were followed for 6 months to evaluate the lesion. Lesion size was measured from scaled photodocumentation with the software program ImageJ®. <i>Results:</i> There were significant differences in IH size after treatment with timolol maleate 0.5% solution compared with ultrapotent corticosteroids (p < 0.001) and timolol maleate 0.5% gel compared with ultrapotent corticosteroids (p < 0.001). There was no significant difference in IH lesions after treatment with timolol maleate 0.5% solution versus gel (p = 0.744). <i>Conclusion:</i> Timolol maleate 0.5% solution and gel were significantly superior to topical ultrapotent corticosteroids in size reduction of superficial IH.
