Minimally invasive treatment of benign oral vascular lesions: A retrospective study

Background: The ethanolamine oleate (EO) in different concentrations has been used in sclerotherapy of oral benign vascular lesions (OBVLs). The aim of the present study was to define demographic and clinical characteristics of patients with OBVLs treated with 5% EO. Material and Methods: A retrospective study was conducted of cases treated by sclerotherapy from 1992 to 2022, and medical records of 52 patients with OBVLs were analysed. Thus, 44 cases with complete data were selected and described. Categorical data were analyzed using the chi-square test, with the significance level set at 5% (p < 0.05). Results: Mean age was 52.89 years (range seven to 82 years). The female sex was predominant (77%) and brown was the most common skin color (54%). Most lesions occurred on the lower lip (65.9%), tongue (11.4%), buccal mucosa (9.1%), upper lip (6.8%) and palate (25%.3%). Approximately 73% of the lesions were <= 1 cm, > 1 <= 2 cm (18.2%,) and > 2 cm (9.1%). Complete regression of the lesions occurred in 97.7% of the cases, with no case of recurrence and no need for complementary surgery. All patients were satisfied with the treatment. Conclusions: Sclerotherapy with 5% EO is a safe and effective method for the treatment of OBVLs.
