Our hypothesis is that EO applied at a Accepted 9 November 2018 concentration of 5% may decrease the number of sessions necessary for clinical healing. Available online 16 November 2018 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. Keywords: Results: Fifteen of the 19 OVAs were varicosities and the lower lip was the most affected site (n ¼ 7). The Ethanolamine median size was 6 mm, and one session was required in 89.5% of cases for clinical healing within 28 days. Sclerotherapy < > Varicose vein The pain/burning score was low ( 2) for most lesions (63.1%) and the degree of satisfaction was high ( 8) fi fi Vascular malformation for all OVAs. The number of applications, nal volume of drug and time to resolution differed signi - cantly 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. © 2018 European Association for Cranio-Maxillo-Facial Surgery.

Vascular anomalies 2007; Drolet et al., 1999). Vascular malformations (VMs) are present are currently divided into two groups: tumors and vascular at birth and affect both females and males. Their incidence in the malformations (Sham and Sultana, 2012; Colleti et al., 2014; head neck region ranges from 14% to 65% (Haggstrom and Drolet, Fowell et al., 2017). 2007; Kobayashi et al., 2013).

The proposal of the current study was to use 5% EO without (Greene, 2012; Sigaux et al., 2015).

Protocol outcome assessment 2005; Costa et al., 2011; Dilsiz et al., 2009). Previous studies have shown the effectiveness of different concentrations of EO (1.25%, Demographic data of the patients (gender, age, and ethnicity) 2.5%, and 5%) for OVA treatment (Johann et al., 2005; Costa et al., were obtained.
