Propranolol for Surgeons in the Treatment of Infantile Hemangiomas

Beta-blocker (Propanolol or Timolol maleate) treatment of infantile hemangiomas (IH) is a safe and effective treatment in the outpatient setting. The authors report a single surgeon's initial experience with setting up an outpatient service of beta-blocker treatment for head and neck IH at a tertiary children's hospital.

A prospective study of children with head and neck IHs commenced in January 2015 with the end point being December 2018. Each child started either oral propranolol (2 mg/kg/day) or topical Timolol 0.5%.

Thirty-eight patients commenced a beta-blocker during the study duration. The mean age at time of starting therapy was 9 months (range 3 weeks to 116 months). Four patients were older than 12 months at commencement. The mean duration of treatment was 9 months. The response to treatment was excellent or complete in 29% (n = 11), good in 50% (n = 18) and mild in 10% (n = 4). The non response rate was 10% (n = 4). No major adverse effects occurred but 29% (n = 11) experienced minor side effects.

Low dose propranolol and topical Timolol is been safe and easy to use for surgeons who may not be regular prescribers or unfamiliar with treating children with IHs with beta-blocker therapy. In patient monitoring is unnecessary and parents can be taught easily to recognise side effects. Treating children from the start builds a trusting relationship with the family before the child requesting cosmetic revision of the fibro-fatty remnant.
