Experience with 5% ethanolamine oleate for sclerotherapy of oral vascular anomalies: A cohort of 15 consecutive patients

Abstract

Purpose: To describe the effectiveness and safety of a sclerotherapy protocol with 5% ethanolamine oleate (EO) at 0.1 mL/3 mm for oral vascular anomalies (OVAs). Our hypothesis is that EO applied at a concentration of 5% may decrease the number of sessions necessary for clinical healing.

Materials and methods: We describe a cohort of 15 consecutive patients. OVAs <20 mm were included. Clinical data of the OVAs were collected. Descriptive and bivariate statistical analyses were performed.

Results: Fifteen of the 19 OVAs were varicosities and the lower lip was the most affected site (n = 7). The median size was 6 mm, and one session was required in 89.5% of cases for clinical healing within 28 days. The pain/burning score was low (<2) for most lesions (63.1%) and the degree of satisfaction was high (>8) for all OVAs. The number of applications, final volume of drug and time to resolution differed significantly according to the size of the anomaly.

Conclusion: The protocol with 5% EO was shown to be effective and safe to treat OVAs <20 mm, and with a decrease in the number of sessions, volume and time to resolution, without complications and with high patient satisfaction.
