Background:
Oral propranolol can effectively activate and accelerate infantile hemangioma (IH) involution; however, could the final outcome of oral propranolol treatment for IHs commensurate that of spontaneous involution?
Objective:
This study aimed to investigate the long-term therapeutic effect of oral propranolol for IHs.
Methods:
We present an individual matching comparative study with (1) oral propranolol therapy for mixed and deep IHs on the lips, nose, and parotid and (2) lesion type- and lesion location-matched untreated IHs as controls. Patients' follow-up photographs were assessed by 3 surgeons blinded of their treatment. Outcome measures were the quantification of the degree of sequelae ranging from 1 to 4 and the age at which IH achieved involution arrest.
Results:
Ten groups of oral propranolol and untreated patients with matched lesions were assessed. Average age at which lesions stabilized and reached no change in appearance was 1.7 years old and 6.3 years old for propranolol group and untreated group ( t = 5.663, P < 0.001). There was no significant difference in the quantified degree of sequelae for oral propranolol group and untreated group upon follow-up (1.60 vs 1.40, respectively; t = 1.259, P = 0.240).
Conclusions:
Oral propranolol therapy accelerates IH involution but does not have a superior effect than spontaneous involution on the overall outcome of problematic IHs.
