Intralesional betamethasone versus oral propranolol for localized infantile hemangiomas of the lip.

Infantile hemangiomas (IHs) of the lips are associated with an increased risk of incomplete involution and ulceration, causing disfigurement. Treatment with oral propranolol (OPT) has credible efficacy but takes months to complete. Thus, this study aimed to investigate the efficacy of intralesional betamethasone injection (IBI) as an alternative treatment for protruding localized IHs of the lips. To investigate the efficacies of OPT and IBI, we designed a prospective, noninferiority, parallel-group study. The primary outcome assessed was treatment response rate. Secondary outcome assessments included lesion size changes and surgical rate. Additionally, complication rates and treatment durations of OPT and IBI were compared. The treatment response rate of IBI was not inferior to that of OPT (95.7% vs. 76.0%, respectively; a difference of 19.7%, 95% confidence interval [CI], -4.4% to 41.6%). The average surgical rate in the IBI group was significantly lower than that in the OPT group (8.7% vs. 40%, respectively; p = 0.012), and the average duration of treatment for IBI was shorter than that of OPT (2.1 months vs. 6.3 months, respectively; p < 0.001). There were no severe adverse drug events in either group. If not managed properly, small, localized lip IHs may cause disfigurement in a child. Our study demonstrated that IBI is as effective as OPT in treating protruding localized lip IHs. Moreover, IBI treatment has a shorter duration and lower surgical rate than OPT. With proper care, IBI is an effective treatment modality for small and localized lip IHs.
